ANSYS - mchining cutting forces

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of analyzing cutting forces in machining processes using ANSYS Workbench. Participants explore whether this can be effectively modeled within the software, considering the complexity of material interactions and the capabilities of ANSYS tools.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the possibility of using ANSYS Workbench for analyzing cutting forces in machining processes.
  • Another participant expresses uncertainty about the feasibility of such calculations, suggesting it may be a significant challenge for beginners and might require more than just built-in functions.
  • A different participant doubts the effectiveness of modeling cutting forces in any finite element software due to the complexity of material interactions at the cutting tool.
  • One suggestion is made to conduct physical experiments using strain gauges on the actual machine to gather data on cutting forces, which could then be compared to results obtained from ANSYS.
  • Another participant mentions that while it is possible to use ANSYS Workbench (specifically Explicit Dynamics) for this analysis, they have not been able to obtain the cutting force outputs they were seeking.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of modeling cutting forces in ANSYS, with some believing it may be too complex while others suggest it can be done with certain methods. The discussion remains unresolved regarding the effectiveness of ANSYS for this specific application.

Contextual Notes

There are limitations noted regarding the assumptions about the modeling capabilities of ANSYS and the complexity of the material interactions involved in the machining process. The discussion does not resolve these uncertainties.

Hi,

I am working to analysis cutting forces of machining process. I would like to enquire whther ANSYS workbench can do that, any idea?
Thanks,,

So, do you know what it would take to do this kind of calculation? If even possible (I'm not sure) it would be a heck of an undertaking for a beginner in ANSYS, and it would take more than just the built-in functions in Workbench...

Thnaks,,
I am asking if it's possible to solve it by applying workbench or APDL?
 
I personally don't think this can be modeled effectively in any finite element software. The complexity of the material interactions at the cutting tool will be basically impossible to successfully model.

My opinion anyway...
 
Do you have the actual machine you want to model? You could run an experiment on the machine and determine the forces, maybe by using some strain gauges. Then you could compare the experimental results to your ANSYS results and modify the model as needed.

Otherwise, your results directly from ANSYS probably won't be exact due to what Mech Engineer said. It would be interesting though to see how close you can get it.
 
Thanks,,,
It can be done by using ANSYS Workbench (Explicit Dynamics). However, I could not actually get the output of cutting forces. I am still asking if it's possible to solve it by applying workbench or APDL?
