Simulation and Optimal Selection of Pitch Angles Distribution for Variable Pitch Angles Helix End Mills

Abstract:

In the paper, a static milling force model for variable pitch mills was built, and the milling forces were simulated. The resultant force and its frequency spectra of variable pitch mills were analyzed compared with that of uniform pitch mills. It is shown that the standard deviation (SD) of frequency spectra amplitudes for variable pitch mills is extremely lower than that of uniform pitch mills. Through simulation for SD of frequency spectra amplitudes affected by the different cutting parameters, a pitch angles distribution of variable pitch helix end mills with lower SD of frequency spectra amplitudes was selected.
