What is a CNC Waterjet?
CNC waterjet is an automated cutting machine based on waterjet cutting technology that uses the force of highly pressurized water for material cutting.

The waterjet is controlled with Computer Numerical Control (CNC) technoogy. CNC programs are pre-written for the particular part beforehand. CNC waterjet is a fully automated, high-precision industrial cutting process.

For cutting soft materials, the force of the water is sufficient. However, for hard materials, the force of the water can lead to a slower cutting process. Therefore, abrasive material is added to the water stream to speed up the cutting action. The process is then called abrasive water jet cutting. CNC can control both pure and abrasive water jet cutting.

How Does a CNC Waterjet Cutter Work?
CNC waterjet cutting is a multistage process. The steps involved are:

1. Designing the Part
An engineering design of the part is created before cutting it. For simple cuts in a straight line, this step can be skipped. However, a detailed graphical design with the measurements is required for complex parts. The graphical design is made in Computer Aided Design (CAD) software.

2. Converting Design to CAM
A CNC waterjet machine does not understand graphical design. It understands CAM language (g-code and m-code). Therefore, the CAD design is converted to CAM in Computer Aided Manufacturing (CAM) software. The CAM file is loaded to the machine control panels.

3. Machine Setup
The operator starts the machine setup for the operations. The workpiece is clamped on the worktable. All the necessary settings are selected and preliminary checks are done.

4. Machine Startup
The machine startup process takes place according to the particular CNC waterjet model. Startup includes the generation of pressure in the hydraulic pump. The hydraulic pump provides pressurized hydraulic oil of around 50 psi to the intensifier. The intensifier increases the hydraulic pressure to 50,000 psi and even more.

5. Execution of Waterjet Cutting
Once the pressure is ready, the cutting operator starts. The water jet cutting head moves around the part while forcing the high-pressure stream of water. The G-code of the CAM file controls the movement. The stream of water is very narrow with a thickness less than a human hair.

6. Unmounting of Part
Once the machining is completed, the part is unmounted from the machine. If the part requires any further machining, the operator mounts it on the worktable again. Otherwise, the part is sent for secondary machining.

What are the Parts of a CNC Waterjet Cutter
CNC waterjet cutting machine comprises of industrial-grade parts that can handle the ultra-high erosion forces at play. The various components of water jet cutting machines are:

CNC Controller
The CNC controller is the brain behind the machine. It reads the commands provided by the software and the settings made by the operator. The combined interpretation is sent to the machine cutting head.

High-pressure Pump
A high-pressure pump creates the necessary force required for the cutting action. It is an assembly of a hydraulic pump and intensifier. The hydraulic pump creates a small pressure which is amplified by the intensifier. The cost of the water jet heavily relies on this part. High-pressure pumps come under multiple settings to adjust the pressure according to part requirements.

Cutting Head
The cutting head is the assembly that moves the stream of water around the work table. A nozzle present in the cutting head focuses the stream of water. There is a mixing chamber before the nozzle in abrasive water jet cutting. The mixing chamber mixes the abrasive material with the water stream.

Abrasive Hopper
The purpose of an abrasive hopper is to store and feed the abrasive material to the mixing chamber. A good quality abrasive hopper can deliver the abrasive material uniformly. Abrasive hoppers can generally store enough material for hours of waterjet cutting.

Gantry
The gantry is the bridge system in the waterjet cutting machine. It provides support to the cutting head and mobile parts of the machine. The gantry bridge system supports the cutting head movement in the X-axis, Y-axis, and Z-axis.

Cutting Table
The cutting table provides a stable base for mounting the workpiece. The workpiece is held securely on the cutting table. Modern waterjet cutters have the feature of underwater cutting. The workpiece can be submerged underwater to provide noiseless and splatter-free cutting.

Water Filtration System
The water filtration system purifies the water and removes any debris from it. This prolongs the life of the components used in the waterjet cutting machine. A water filtration system usually includes a softener for fixing the hardness of the water. The filtration system should be designed based on the type of water source you will use.

Control Panel
The control panel provides a medium for the operator to interact with the machine. Various settings of the waterjet machine can be selected through the control panel. Control panels also come with a display for viewing relevant information.

Software
Waterjet machines come with a software that acts as the language between the controller, the operator, and the machine. The functionality of the software can vary based on the machine. Every Techni Waterjet cutting machine comes with complimentary software. The software contains many basic cutting shapes preloaded in the system.

Different Types of CNC Water Jet Cutting Machines
CNC water jet cutting machines are available in many different configurations. The use of a particular type is based on the requirement of the operation. These different types of machines are:

One-dimensional Waterjet Cutting
One-dimensional waterjet cutting can also be seen as single-axis cutting. In this method, the waterjet cutting heads can only move in one direction. This method is used for straight linear cuts. Generally, this technique is applied to the processing of raw materials.

Two-dimensional Waterjet Cutting
Two-dimensional waterjet cutting is also known as 2-axis waterjet cutting. The cutting head can move on the X-axis and Y-axis. These machines can cut linear as well as circular cuts. However, they cannot create inclined surfaces or curved cuts in the vertical plane.

3-axis Waterjet Cutting
3-axis waterjet cutting machine can move the cutting head in the X-axis, Y-axis, and Z-axis. The X-axis is left and right movement across the worktable. The Y-axis is the top and bottom movement across the worktable. The Z-axis is the vertical movement perpendicular to the worktable.

4-axis Waterjet Cutting
4-axis waterjet cutter can move in the linear X-axis, Y-axis, and Z-axis. In addition, it can also move in the rotary A-axis. A-axis is the circular axis around the X-axis. 4-axis waterjet cutting can make curved cuts and machine five sides of the workpiece.

5-axis Waterjet Cutting
A 5-axis waterjet cutting machine is the most capable option among the different types. It can cut linearly in the X-axis, Y-axis, and Z-axis. In addition, the cutting head can also move in any two of the A-axis, B-axis, and C-axis. A-axis is rotary around the X-axis, the B-axis rotary around the Y-axis, and the C-axis rotary around the Z-axis. 5-axis cutters can create linear, curved, and inclined parts. It can also craft parts with internal features and geometries.

What Materials Can a CNC Waterjet Cut?
Waterjet cutting can cut through virtually any material except for only diamond and tempered glass. Some of the common materials that undergo waterjet cutting process are:

Metals
Metals and metal alloys commonly undergo waterjet cutting process. Some of the common metals utilizing this technique are:

Stainless Steel (all grades)
Aluminum
Carbon Steel
Mild Steel
Tool Steel
Copper
Brass
Iron
Chrome
Nickel
Titanium
Platinum
Gold
Glass
Glass can be delicate to cut through traditional means. However, waterjet cutting can pierce and smoothly cut any type of glass with ease. Some common examples are:

Plain glass
Frosted glass
Reinforced glass
Mirrors
Glassware
Stone
Waterjet cutting stone and tiles is a very common application of the method. It finds common application in kitchen countertops, flooring, cladding, and other areas. Some of the common stone and tiles cut by CNC waterjet cutting process are:

Marble
Granite
Tiles
Porcelain
Silestone
Caesarstone
Composites
Composite metals are made by fusing multiple materials together. Composites can be tough materials for conventional cutting processes. However, waterjet cutting can easily cut it. Some of the common composites cut with water jet cutting are:

Fiberglass
Fibre Reinforced Plastics
Carbon Fiber
Plastics
Water jet cutting provides a lot of benefits when cutting plastics. CNC waterjet is a cold cutting method. Therefore, plastics do not release toxic fumes on being cut with water jet cutting. Some of the common plastics that undergo water jet cutting are:

ABS
Styrene
Polythene
LHDP
UHDP
Nylon
Rubber
CNC waterjet cutting also shows exceptional performance when cutting rubber. While rubbers are soft materials, conventional cutting processes create heat which can cause the rubber to harden. However, waterjet causes no such issue. It can cut any rubber with extreme precision.

Paper Products
CNC waterjet cutting is common in the paper industry. It applies to paper, paper reams, and paper based products like cardboard. Due to the softness of paper products, pure water jet cutting is enough to accomplish the task.

Wood
CNC waterjet cutting of wood is usually implemented in the furniture industry. Water jet cutting process can create intricate shapes from wood, such as carvings. Waterjet cutting can also cut plywood without causing any delamination issues.

What is the Maximum Thickness of CNC Water Jet Cutting For Different Materials?
Waterjet can cut most materials up to 24″ in thickness. The range of maximum thickness of water jet cutting varies based on the type of material. For instance, it can cut hard metals and alloys up to a thickness 12″ to 18″ (depending on the machine). It can cut soft materials many times that thickness.

The maximum thickness does not mean that a water jet machine is limited to that value. Theoretically, the water jet cutting process can cut any thickness of any material. However, the cutting time increases significantly beyond a certain thickness. Additionally, thicker materials lead to slower cutting speed. The maximum thickness is the value after which the cutting speed and time can become unfeasible.

How Accurate is CNC Waterjet Cutting?
CNC waterjet cutting can have a tolerance as low as ± 0.002”. This makes CNC waterjet cutting one of the most accurate cutting methods. The exact tolerance of water jet cutting process depends on the particular material being cut. Maintaining the machine and doing the setup right can increase the precision of waterjet cutting.

Benefits of CNC Waterjet Cutting
The CNC water jet cutting process provides many advantages that are unmatchable with other cutting techniques. Some of these benefits are:

No Heat-affected Zones: Heat-affected zones are caused by localized heating due to cutting friction. Water is a coolant in itself. Therefore, water jet cutting causes no heat-affected zones.
Preserving Material Integrity: The material integrity remains intact due to the absence of heat zones. There are no burn marks on the material surface.
Precision: The narrow stream of water results in a very high-precision cutting process. Water jet cutting has higher accuracy than alternative cutting methods.
Edge Quality: Water jet cutting has a superior edge quality. This is the result of the material erosion that takes place on a particle level. Waterjet cut parts require no secondary finishing.
No-contact Cutting: Water jet cutting does not require the contact of the tool with the workpiece. The high-pressure stream is enough to make the incision. This reduces the tool wear and calls for less frequent tool changes.
Costs: Water jet cutting keeps the cost of operation manageable. Pure water jet cutting is a very cheap process. Abrasive water jet cutting has the cost of abrasive as the primary operational cost.
Versatile: Waterjet cutter is the most versatile cutting option out there. It can handle all cutting materials regardless of their shape or form. This includes metals, non-metals, ceramics, composites, glass, paper, etc.

What is the Cost of a CNC Waterjet Machine?
The average cost of a good CNC waterjet machine is $100,000. You can find cheaper models starting at $50,000. However, these models will lack the quality and features that any job requires. Therefore, if buying a new waterjet CNC machine, $100,000 can be a good initial investment. The exact cost of CNC waterjet cutting machine can vary based on several factors.

What is the Expected Lifespan of a CNC Waterjet Cutting Machine?
Waterjet cutting machines can easily last for over 25 years. However, some parts of the machine have a shorter lifespan and require frequent replacement. These parts include the nozzle, seals, valves, tubes, and other components dealing with the high pressure stream.

What are the Safety Considerations For a CNC Water Jet Cutting Machine?
A CNC water jet cutting machine is an industrial tool. The forces it generates can cut the hardest material. Therefore, it requires extreme safety considerations. No human tissue should come under the machine during equipment operations. The machine should be operated by skilled professionals only. The operator requires safety training on the machine before using it.

Maintenance Schedule For CNC Waterjet Cutting Machine
Following the correct maintenance process for waterjet cutter can result in high quality operation and long equipment life. Some of the important maintenance considerations are:

Check the degree of wear for parts such as nozzle before operations. A worn out nozzle can result in poor quality cuts.
Drain the pneumatic filter regulator of the machine every week.
Release the build-up gases in the waterjet machine every week. Water vapor buildup can be a common issue in a waterjet cutting tool.
Regularly clean the water strainer. The frequency depends on the type of materials you cut.
Grease the various bearings of the machine once every year.

How to Choose a CNC Water Jet Machine?
Going through a detailed buying guide for water jet machine can help in making an informed decision. Some of the important factors to consider when choosing a new water jet are:

Pump Pressure: Pump pressure depends on the type of materials you want to cut. Required cutting speed also plays a crucial role in this.
Abrasive vs. Pure Water Jet Cutting: Pure water jet cutting can be cheaper for soft materials. However, hard materials require abrasive waterjet technology.
Brand Value: It is better to go with a reputed brand, even if it costs you a little extra. Machines with good build quality can avoid downtimes and operational losses.
Spare Parts: Ensure that the spare parts for the machine are available when required.
Techni Waterjet’s G2 series is often considered the best by professionals in many different industries. These machines come with a rugged build quality and the features of waterjet machines that are twice the price range. The machines come with a complimentary software with preloaded programs for basic cut shapes.

What is the Difference Between CNC Laser and CNC Waterjet?
CNC laser and CNC waterjet both utilize Computer Numerical Control. However, there are vast differences between CNC laser and CNC waterjet cutting. The waterjet process is considerably better than laser cutting. A laser uses high-energy light rays to melt the material. This leads to adverse heat effects on the material. The materials can require secondary finishing due to burn marks.

However, the waterjet process does not create any adverse effects. Additionally, the waterjet can cut through virtually any material. CNC lasers have shortcomings in this area. Materials like plastics release toxic fumes when heated. This can damage the laser tubes, rendering CNC laser cutting unusable.

Endnotes
CNC waterjet is a breakthrough technology for cutting hard materials and soft materials. The precision and versatility of the process are very incomparable. Additionally, being a cold-cutting process, a waterjet cutter is a more attractive option than alternatives such as plasma cutting.

I use this software mainly to move videos between PC and DVD-RAM in either direction. I download videos in various formats to burn onto DVD-RAM, but as I do this only rarely I keep forgetting the exact procedure. I know I have to
(1) use the Editor to read in the video,
(2) convert it into some other format, and then
(3) use the VRCopy output option to add the converted file into an existing/empty DVD-RAM.

What I can never remember properly is the second stsge - conversion. Can anyone enlighten me?

TME2 is not a video converter. Your input video must be compliant with the output format.

After editing some MPEG files, I get an error message of
"this window size is not supported in the selected level".

What setting do I need to change?

Every so often my TMPGNC crashes during VBR, at the half-way point, AFTER creating the "log" file. Is there a way to now complete the encoding with the existing log file, so it doesn't have to do it all over again?

I saved a movie to DV after using Windows Movie Maker (WMM) to add titles. The resulting avi, whether I use WMM or Pixella to download it from the camcorder has audio at a significantly slower speed than the video when played by TMPGenc 4.0 XPress (4.2.3.193) on the clip screens, on the encode preview, and on the final encode ac3.

When I play said downloaded movie in WMM, it plays fine, and WMP plays it fine. Using TMPGenc, the movie played fine, prior to adding the WMM titles.

What do I have to do to adjust TMPGenc or do I have to fix the file?

Thanx,
Eski

Hi,

I'm trying to make a dvd file, but the output file will be 118 percent of the dvd's capacity, and I cant set it to 90 percent of the disk (looks like the function is disabled) the original file is about 900mb , I want to convert it to Pal 16:9 625 line.

thnx in advance.

Vladd.

I want to take a DVD and edit out the bits I do not want including audio.

I tried with DVDshrink reauthoring but it was not very precise particularly the sound part. Will TMPGenc edit or authoring be best?

Hello. I have recently installed Editor Premium on a powerful Dell which has been dealing with TMPG 4.0 Express and Editor 1.0 for many months without any problem. If I start a new project (or open an existing one), add some files, open the transition editor, optionally select a transition (or not) and then select OK to close the transition editor, the program displays a message "runtime error 204 at 0BOA29FC" and crashes.

TMPG Support said:
"It is possible you may have other processes in the background that is
causing a conflict with our software. Please make sure you close down
all processes that are not needed. I also recommend having the latest
.NET framework 2 and 3 and DirectX installed. Also, if you have any
codec packs or ffdshow then I suggest removing them as well."

I hardly have any startup programs. I have now run all Windows updates (including .NET fraework 3), have updated DirectX and have updated the ATI dispay driver. I'm 99.9% certain that the ffdshow codec pack has never been installed - I have been warned against it many times on the web.

Google identifies 2 oriental websites mentioning "error 204" +pegasys, but I can't understand them.

I have found kservice.exe and removed it. No improvement.

Any ideas would be most welcome. Thanks

What kind of graphics card do you have? Their spec says 3D graphics card with DirectX 9 capabilities. You could have the software DirectX 9 installed but if your card isn't directx 9 compatible then this could be a problem.

oh yah btw, you might not want to quote them...they usually have a disclaimer and might not like you using it for posting on blogs or forums.

One other thing I do know is that Runtime error is an error in memory conflict at runtime.

>What kind of graphics card do you have? Their spec says 3D graphics card with DirectX 9 capabilities. You could have the software DirectX 9 installed but if your card isn't directx 9 compatible then this could be a problem.

Thanks nTekka. My graphics card is an ATI Radeon X600 256MB HyperMemory and the spec on their website says "Full DirectX 9 support".

I'm not sure how to detect whether I have codec packs or ffdshow installed.

Thanks again. Mike

I have the same problem on two systems with TMPGEnc editor. All my frameworks are up to date. No extra codecs installed. It crashes the system every time I use a transition. Have submitted a report every time as well. Any news on this? This pudate has been a waste of money if this is not fixed at some point.

Is there any news on this? I still cannot use the transition editor.

I just purchased and installed MPEG Editor v2 Premium, did a quick test project, primarily to get the license, and make sure things worked, and they did, so I shut it down. I then tried to browse the internet using Firefox, but my firewall allerted me that TMPG MPEG Editor was tring to access the internet by sending commands to explorer.exe. The only programs that I know of that try to access the internet without the knowledge of the user, are securty threats. So when I denied access (via the firewall alert), my browser was inoprerable, unable to connect to anything. After a while trying to intercept this behaviour I was forced to de-install MPEG Editor 2 and reboot, before the internet was accessible. Is this behavior intended?

iono about that... sounds suspicious to me and I don't mean with MPEG Editor. Why would it access explorer.exe (your Windows explorer) and not iexplorer.exe (Internet explorer)... but anyway how is all that connected to Firefox and MPEG Editor 2P? give us some details...sounds like you might got a piggy back riding trojan off of MPEG Editor 2P.

I used TempEnc to removed a clip from a large video clip and it worked with any error messages - just checked the clip and there is no sound... next time I tried the same huge clip only minutes after the first time I have error "-537403781 180576" which I didn't get the first time...

I have no problem what so ever with Media Player.

What does -537403781 180576 mean??????

Only reference I found while googling is a german forum and my german is so rusty its not worth mentioning but I did see it had to be a codec problem.

This is the info I get with Gspot when I render:

DirectShow claims to be able to play the file. The following combination of filters were used:

{B:\Movie maker\RAW 20050606.avi} (Source)
{AVI Splitter} (Splitter)

{Xvid MPEG-4 Video Decoder} (Video Decoder)
{Video Renderer} (Video Renderer)

{MP3 Decoder DMO} (Audio Decoder)
{Default DirectSound Device} (Audio Renderer)

This is the audio info:
Audio Format:
Code: 0x0055
Name: WAVE_FORMAT_MPEGLAYER3 (MP3)
Vendor: ISO/MPEG

The following codecs all claim to be capable of processing this format:

--> {Fraunhofer IIS MPEG Layer-3 Codec (decode only)}
{Nero Digital Audio Decoder}
--> {MP3 Decoder DMO}

Plz help me... it works one minute and the next the file doest work with Temp anymore but it works perfect with Media Player the whole time... Plz help...

OK I tried with another huge clip to see if it worked and now I got error code... -537403781 446818...

WHAT does that code mean??? What is happening to my Temp??? Plz someone help me...

Tried yet another clip that gives me error code: -537403781 279776

SHOULD mention that all these times is it avi files and I have DivX and Xvid installed...

Also the Windows Movie Maker is giving me problems... maybe the problems are related???? MM crash and TempEnc gives me error codes...

Your under MPEG Editor 2 thread and that program doesn't support AVI format. So i'm assuming you mean TMPGEnc 2.5? How large is your video clip? dimension, bitrate, file size? What output format did you use? I think it might be your encoder, if you are using AVI Xvid or DivX for re-encoding the setting might not be correct. Those kind of errors isn't normal for TMPGEnc type of error.

The videos is different in sizes... they are sometimes around 700 Mb and sometimes smaller. Dimension, bitrate = I have no idea... not bother what those things... its more info than I need to know... I just want a piece of the large file... output is normally PAL if I understand what output means correctly... after I get those errors and keep using the program there is no sound on the finished result...

Hey Ellie,
seems like a codec issue to me. TMPGEnc doesn't support MP3, so you will need an external codec to decode it for audio. Go to videohelp.com and look for LAME MP3 codec or on freecodec.com

Are you using MPEG Editor 2 or TMPGEnc 2.5? both software are completely different and I can't help without knowing which one you have.

Hello, I start new project and import from DVD source. I want to be able to select many certain parts of the DVD to add to the project as one file. Whenever I select a part to cut out it does not cut it in the right place. It leaves a part of the frame...a very brief blip of the frame. I move the cut exactly over the head but it always cuts just a bit before or after the head leaving a bit of the frame in the final movie.

The only way I've been able to work around this is to make the selection I want and click OK, then I have to import the DVD source all over again to select another scene from the DVD. I have to do this with every scene I want to include in the final movie. This tool is suppose to be easy to use, but in reality it is not easy.

Questions:

Why won't it cut properly?

Why do I have to import the DVD source each time I want to select a scene to add to my movie?

It might be normal that there seems to be a frame left behind, it's probably just the way TME2 displays the frame. If you right click on the preview area and select thumbnail display settings > I Pictures only then you won't see that 1 remaining frame. TDA3 does a better job at displaying the frames, it can display 1 frame at a time so you don't get that remnant frame, but this doesn't affect your video.

If you want to split your chapters up then try using the Split tool next to the chapter flag on the lower left corner. It will split the video into however you want into separate clips so you don't have to re-import every time you do a cut.

Thanks for your help. Ok I see what you mean now. It doesn't include those little blips in the final encoded file. It is a bit deceiving. Why does it do that? I've not seen any other editors do that. Is there a reason?

I can only assume its the way the developer wanted to display the frames as I-picture so its easier to re-encode or they placed it that way as a flag to let the program know what is going on.

Hello... I am trying to edit some video clips... I can without problem take mpg and cut it etc... but when I choose .avi I only get video!!! The sound WONT come up!!!! I have no idea what to do... have tried everything... am I missing codecs or something???

Plz help me!!!!

I need my program to work... plz...

You may be right, probably a missing codec, either AC3, AAC or MP3. Likely MP3 because your using AVI container. Use GSpot on your source video to find out what audio it uses then download the appropriate codec online somewhere.

Let me know if i'm way off or if you run into some other problems.

I have used Gspot already and it say that I aint missing any codecs... I have no idea what is wrong... Gspot said everything is working and all codecs are in place... but I am gonna try clean regedit once and then install TMPGEnc again and if that doesnt work I will upgrade codecs anyway...

Could this problem have anything to do with the fact that I dont have Windows Media installed? I only have window media classic installed because I use other programs to watch video clips..

ooooooooooook I decided to try with "lots of stuff" option instead of custom option on codec install and now avi is showing up... damm it was codec all along... problem solved...

oooooooooooooooooooooooooook me yet again... program is now showing audio link also under video link BUT when I try to edit the clip only video ends up... still NO sound... what the heck is the problem????

before audio wasnt showing but now it is.... still need help guys...

ooooooooooooooook but this time it would help if you can tell me what audio codec your avi file uses. Probably best if you simply download a codec pack with all the codecs you ever want to use, but be warned this could cause problems later on if your unorganized. It will probably work for the meantime tho, go to www.freecodec.com and download K-Lite 3.25 Full, then load up TMPGEnc 2.5 and import your files again. Also make sure that you have DirectShow file reader enabled in the Options > Environmental settings > VFAPI Plug-in and uncheck AVI file reader so FFDShow can kick in to decode your file.

Let me know if this works.
