Hello,

My task is to create a turning simulation of the object shown in the attachment and then machine the object. The object will be machined on 3 axis lathe, x,z,c. The lathe is single point diamond turning machine – Nanotech 350 upl. I am looking for a proper software which will allow me to generate g-code and simulate the machining process (toolpath simulations). I was trying to do the simulation in Catia and NX but I couldn’t do it because of sinusoidal surface and software constrains. Any good proposition of CAM software that will help me with my task will be very valuable to me.
However, if there is a way to generate the turning program and simulation on Catia or NX, please go ahead and describe a way in which I could do it. Thanks, in advance for your reply.

Here are some links that show videos of the process I will need to use for this part:

I know this post is old, and I apologize for the thread necro. The commercial software that would handle this are DIFFSYS from Precitech and Nanocam3D from Moore Nanotech.

For fun I put together a program to do similar using ncplot. I haven't tested it yet so it might need a little tweaking but if someone were to run the program then I would 'expand' the program into XZC coordinates prior to running on a control. There is no tool compensation on this program, as all of the surface slope is perpendicular to the axis of rotation. If you have the money go with DIFFSYS/NanoCAM3D otherwise...
