Gear honing with globoid honing worms is seldom used because it has no distinct advantages to honing with internal geared honing rings. The paper puts forward a new process to honing gear with globoid honing worms on hobbing machines. First the globoid honing worm is profiled by diamond dressing gears, which has the same geometric parameters with the machined gears. Then the profiled globoid honing worm is used to hone workpieces. Both the profiling process and honing process are implemented on same hobbing machines. Meshing and Tooth contact analysis of globoid honing worm profiling has been considered. Meshing equation of profiling process and equation of globoid honing worm tooth flank after profiling are obtained. Experiment testified that it is an applied process and has many advantages.
