DeskProto offers true rotation axis machining, with the part rotating while cutting. This tutorial video covers a number of advanced rotary topics, including how to combine rotary with plain XYZ toolpaths, chaining and dummy operations. It shows both setting the DeskProto parameters and executing the resulting toolpaths on the machine.
The video features Queen Nefertiti of Egypt, including information on the "Nefertiti hack" and a download link that will allow you to machine your own version.

That's a really good tutorial Lex. It's answered so many questions I had on rotary axis machining and now I feel so much more empowered. I didn't realise you could set different parts graphically and machine them separately and also do XYZ machining on the rotary axis. If I have translated the rotary to YXZA to machine along the Y axis do I need to change this to do XYZ machining as well? Thanks for clearing up a lot of things. :-) Richard.

@Deskproto 7 жыл бұрын

Hi Richard, sorry for the slow reply, due to our company vacation period. When you have edited the postprocessor to accommodate a rotation axis parallel to Y (so swapped X and Y), the X and Y will also be swapped for normal 3-axis jobs. You then can best use two different versions of the postprocessor (and also two different machine definitions): one for 3-axis jobs and one for 4-axis jobs.

Thank you so much When you switch the cutter from roughing to finishing, how do I know a zero point in a rotary machine

@Deskproto 6 жыл бұрын

Hi Mohamed, When changing the cutter the X=0 and Y=0 do not change, only the Z=0 as the new cutter will have a different length. So you need to take care when setting the Z=0 for the first cutter: use a method that you can repeat for the second cutter. For instance by setting Z=0 a certain distance above the working table of your machine. Success !

Will the 4 Axis abilities allow me to create complex geometries? In example, can I cut on the 4th Axis, a 3-D viking longboat made of wood, or a carving of a 3D human? Front, back, and both sides of each of these projects?

@Deskproto 5 жыл бұрын

A longboat and a complete human will indeed be more complicated than the bust as shown in this video. The video shows that when machining with continuous rotation certain areas cannot be reached (in the video the areas behind the ears and below the chin). For a boat and a human figures these areas will be much larger. You can solve that by using XYZ machining from various rotation angles (this is called "indexed machining"), as shown in the video. DeskProto also offers a wizard for this type of machining.

Hi. please answer: is it possible to milling on 3 axis machine, provided that one of these axes - axis of rotation, milling the part below the axis of rotation? Thank you

@Deskproto 7 жыл бұрын

These are in fact two questions: 1. Can you use DeskProto for rotation axis machining on a 3-axis machine 2. Can you machine below the axis of rotation. 1. Yes: when rotation axis machining DeskProto does not move the Y-axis: only X, Z and A are used. So this can be applied on a 3-axis machine. 2. Yes, this is possible. When you check "Use rotation axis" DeskProto by default limits the part segment to "Upper half of geometry", so with the minimum Z at the rotation axis, as that is OK for most geometries. You can overrule that and for the Part segment select "use whole geometry". Important is that the workpiece zero point now needs to be set EXACTLY with the tip of the cutter on the rotation axis. Any small deviation will be clearly visible in the resulting part.

This is a great tutorial. But I would have liked to see how you set the work piece XY=0 and Z=0. I would also have liked to see the initial movements of the machine. Particularly after changing cutters. I tried setting my machine up for rotary. It has X and Y switched compared to DP. But the origin setting seems to get set to the chuck end rather than the tailstock. So when it starts, it tries to crash into the tailstock.

@Deskproto Жыл бұрын

This crashing the tailstock does indeed look like an error in setting the correct zero point. I agree that it would be great if we could include that in the tutorial - unfortunately we can't as the instructions depend on which machine you are using (or rather its controller). For most controllers you can move the machine to a certain location and then tell the control software that the zero point is on that location. For rotary machining with a Z=0 on the rotation axis that needs to be done before the block is loaded.

@privacytest9126 Жыл бұрын

@@Deskproto Thanks for the reply. I think I solved it by setting it to the geometry centre, as X and Z are fixed it's just the rough centre of the material block. I solved the z setting by cutting a block of wood to exactly match the centre of the rotary axis, then I use the z tool calibration to get that height automatically.

Ok I have more questions on this. How are you able to tell that you will need to add a water line? I was trying to mill out a skull out of aluminum and didnt think I would run into any issues. I then began to notice after breaking a bunch of bits that the previous cutter does not cut out certain parts of the model so when I bring in a finer cutter, it plunges too deep trying to remove material that the previous cutter did not remove. Since the plunge is pretty deep or too much for the tapered ball nose to handle, it causes my 4th axis to skip steps and loose it’s position or it breaks the bit. This is what happened when it got towards the chin area. It made me wonder why it wouldnt just start from the top and make it’s way down rather than trying to plunge all the way down.

@Deskproto 5 ай бұрын

This may of course happen, for instance for a hole in the part that is not wide enough for the roughing cutter. DeskProto does not have a trick to do this automatically. What may help is to show a simulation of the result after roughing. For rotary machining the simulation option to show all rest-material in green is not available though.

@metallicaandchimaira 5 ай бұрын

@@Deskproto would I then need to add a water line with a smaller bit if the larger cutter does not remove material by the chin because of how thick it is?

@Deskproto 5 ай бұрын

@@metallicaandchimaira That is correct: when the thick roughing cutter leaves some hole in the part unmachined because it is too thick, the small finishing cutter will go to the full depth in solid material. Using waterlines (from top to bottom) will help to prevent overloading the finishing cutter.

@Deskproto 7 жыл бұрын

Yes, you need a machine with a rotation axis (4th axis). For rotary machining the Y-axis is not used so in fact a 3-axis controller is sufficient. This is complicated though as you then need to switch between connecting the controller to the Y-axis and to the A-axis.

@Deskproto 7 жыл бұрын

Indeed when rotation axis machining in DeskProto only three axes are used: X, Z and A. This is explained in the video, where both XZA toolpaths and XYZ toolpaths are used. For XYZA toolpaths you will indeed need very expensive CAM software like Powermill.

@Deskproto 6 жыл бұрын

Hi Ismail, Indeed DeskProto assumes that the rotation axis is parallel to X. You can change that in the Machine definition in DeskProto: Options > Library of machines > OK on warning > Select your machine and press Edit. The rotation axis settings are in the Advanced settings: there you find the option that you need to check: "Machine with 4th axis parallel to Y". Use the Help button in that dialog for more information.

thanks but not found i checked in machine lib/edit/advance setting/option but no option found there shows only 4th and fifth axis setting my machine is selected Mach2 / Mach3 based machine with RotAxis - mm

@Deskproto 6 жыл бұрын

Hi Ismail, When this option is not present you will be running DeskProto V6.1: the option has been added in Version 7. So one solution is to switch to V7. A rotation axis parallel to Y is possible in V6.1 too, however it is more complicated. See www.deskproto.com/forum/forum.php?forumsubject=1&topic=176

Hello, first of all thanks for the tutorial! All very clear and useful. I didn't understand only one thing: As zero point the geometry center was set, how do I set it on the cnc (using mach3)? I always set the zero point on the surface of the geometry thinking it was the right way... Thank you very much and have a nice day!🙂

@Deskproto Жыл бұрын

Hi Jonathan, Both ways are correct: some machinists prefer the Z=0 at the outside surface of the block, some prefer the Z=0 at the rotation axis. This latter way has the advantages that the zero is the same for all blocks, and that the block size needs not be accurate. You need to set it before clamping the block on your rotation axis. You can check if it is correct by (for instance) moving op 10 mm and then machining a full circle: the diameter of the resulting part then needs to be exactly 20.0 mm. If you like you can then machine a reference block at exactly that Z=0 height, to be used the next time that you need to set this Z=0.

@Jonathan-cs9si Жыл бұрын

@@Deskproto Thank you for your kind and precise answer! Only one small step is not clear for me: once I have set the zero point without block, I move the Z axis to the necessary distance from zero (maybe Z=100), I mount the block on the rotation axis... and I start machining from the point where I left Z-axis (X=0 Y=0 Z=100)?

@Deskproto Жыл бұрын

@@Jonathan-cs9si Yes, that is exactly correct. The position of the cutter when starting the toolpaths is irrelevant (as long as it is high enough): it will simply move from where it is to the first point of the toolpath.

@@Deskproto oo ok yeah that’s what I was going to ask next. So in order to not have to do these steps can they be resolved using a tapered ball nose instead? Or can you encounter this problem again if you have a pretty thick stock? The reason I ask is because I want to use this program to do a bust of my face but I will be trying to use a 3.5in(88.9mm) diameter dowel. However, the max cutting length of my tapered ball nose is 15mm but I dont not want to use the full length or it will hit the collet. So really the cutting length would really be like 10mm.

@@metallicaandchimaira With a tapered cutter you can surely skip the semi-finish. The roughing process still will be much more efficient using a ballnose cutter: you then can use a larger distance between the toolpaths. See for instance www.deskproto.com/gallery/xmasdecoration.php (though here the total height of the part is so low that roughing could have been skipped).
