Simulation of micro-texturing by using elliptical vibration cutting

[Vxxxxx]

Hi, I am wondering if ABAQUS is possible to realise micro-texturing simulation by using elliptical vibration cutting.
I am aware that most of the simulation for micro-texturing are done on MATLAB but I would like to simulation the cutting process by using elliptical vibration cutting.

I am wondering if I could:

Case 1: Vary and control the amplitude of my vibration during the simulation process
Case 2: Maintain the amplitude of vibration but control the tool path

OR any other suggestions that ABAQUS can do.

It would be great if someone could offer some suggestions/advice. Thank you.

Yes, it should be possible to perform such simulation in Abaqus. You can use periodic amplitude definition to model the motion of elliptical vibration cutting tool.

Hi FEA way, I am aware of period amplitude and actually I have already performed elliptical vibration cutting, but my question is that is it possible to machine a micro texture? like for example a dimple.

Right now elliptical motion of the tool isnt the problem, but how to control the tool path/vary the amplitude of the vibration to machine a micro dimple where the tool is vibrating elliptically.

Because if I couldnt control tool path/amplitude of vibration during the cutting process, I coulnt create a curve bottom, instead I will only get a flat bottom.

You can perform analyses in micro scale using Abaqus. There are some articles describing the use of this software in micro scale manufacturing operations like creating a dimple.

Another issue is obtaining the right pattern of the tool motion. This can be achieved with the right combination of boundary conditions but you may also need subroutines for some advanced paths.

Hi FEA way, Thank you for your advice!

I am wondering which subroutine should I look into? since I had no experience on working on subroutines. Thank you.

 

[FEA way]

The following subroutines can be useful for you: UAMP/VUAMP (user-defined amplitudes) and DISP/VDISP (user-defined boundary conditions). V in the subroutine name means that it’s used in Abaqus/Explicit analyses. They are all describe in the documentation

Okay Thank you very much for your info.
