Abstract

In process of cutting tooth surface on planar worm gear

the single-indexing form-cutting method is with low-level efficiency

operation complexity and high error-ratio. To avoid these defects

a continuous-indexing form-cutting method was presented. A mathematical model of fly cutting was proposed by adopting the moving frame

the majorized function was established for minimizing the maximal error. The gyration radius of fly cutter and slope angle of cutter holder were optimized. The error of finish surface in the case was controlled in ±0.01 mm

the surface and error distribution were simulated. The machining precision was tested by contact check-up. It is noted that the red contact mark appearing on tooth surface of worm gear coincides well with the theoretical contact area.
