Cutting force comparison method

Cutting force comparison method

Cutting force comparison method

Hi, I am conducting 2D orthogonal cutting of certain material and I want to compare the results of cutting force from different cutting speed.

So for example, I have using 50mm/s,100mm/s and 150mm/s, my question is, should I take cutting distance or the step time constant?

If I take the same step time (0.01s) for all 3 simulation, eventually they will have different cutting distance.
If I take the same cutting distance (1mm) for all 3 simulation, then they will have different step time at first.

I am currently using approach 2, but I am not sure if it is correct. Or both of these approach do not matter as long as the cutting force is stable at certain cutting distance?

Thank you very much.

RE: Cutting force comparison method

Constant cutting distance seems like the way to go here because with this approach you can compare various cutting speeds realizing the same task (machining the same workpiece).

Noted, thank you very much FEA way!
