Dynamic Model and Experimental Verification of Milling Forces for Forming Process of Helical Gears
摘要
Abstract
A dynamic prediction model for helical gear milling forces,incorporating helical characteristics,was developed.This work aimed to address the problem that existing force calculation models for disc-type gear milling cutters neglect the geometric features of helical tooth surfaces and are thus unsuitable for helical gear machining.Firstly,based on the helix equation of the helical gear tooth surface and the constraint conditions of the tool revolution surface,the tooth profile of the disc-type gear milling cutter for helical gears was precisely solved.Then,using the dynamic meshing relationship between the tool and the workpiece,cutting width calculation models for different machining stages of the helical gear were established respectively.Considering tool runout,an accurate cutting thickness calculation model was also established.Finally,the instantaneous cutting area was obtained through the combined calculation of dynamic cutting width and cutting thickness.By incorporating material properties and cutting force coefficients,a dynamic prediction model for form milling forces was finally constructed.The model was experimentally verified through actual cutting tests.Results showed that the maximum prediction error of the proposed model was 12.57%in the feed direction and 21.01%in the depth direction.A good consistency between the predicted waveforms and the experimental data was observed.Furthermore,milling force analysis for helical gears with different helix angles indicated that the milling forces in both the feed direction and the depth direction exhibited a decreasing trend as the helix angle increased.关键词
