基于试切误差补偿的斜齿插削技术与实验
Helical Gear Shaping Technology Based on Error Compensation by Trial Cuts and Experiments
摘要
Abstract
A machining technology based on error compensation by trial cuts was presented for improving machining precisions of a helical gear for CNC gear shaper.Firstly,the ideal main motion curve was derived using some straight lines approaching the ideal main motion curve,where the maximum allowable step of each straight lines and the corresponding crank angles that might satisfy the demands of machining precision were calculated.Then,the deviations of the main motion curve were calculated by the helix deviations of gear trial cuts,and a new more accuate ideal main motion curve was derived.At last,the new ideal main motion curve was approached by some straight lines again in the G codes used final gear machining.The test results show that the helix deviations of machined helical gears achieve 7 level accuracy,and satisfy the demands,and which verifies the feasibility of the method presented herein.关键词
