INFLUENCE OF WHEEL STRUCTURAL PARAMETERS ON MACHINING ACCURACY OF ULTRA-PRECISION PLANE HONING

摘要

A new idea for designing wheel patterns is presented so as to solve the problems about machining accuracy of workpiece and wear of honing wheel in ultra-precision plane honing. The influence factors on motion principle and pattern structures are analyzed and optimization machining parameters are obtained. By calculating effective cutting length on the surface of workpiece cut by wheel's abrasive and the orbit of one point on the surface of workpiece contacting with wheel, the wear coefficient of different kinds of wheels and accuracy coefficient of workpiece machined by corresponding wheels are obtained. Furthermore, the simulation results show that the optimal pattern structure of wheel turns out to have lower wheel wear and higher machining accuracy.
