Abstract: Gear grinding process is the last fine process after heat treatment of the gear. At present, the industrial circles mostly use the worm generating gear grinding for mass production of gear grinding process. The worm generating gear grinding machine used by industries in Taiwan was imported from abroad, and the cost of controller is often considered to account for 30% to 50% of the machine. In this article, first we establish the theoretical involute worm mathematical formulas and then describe the spatial relationship between worm and gear by coordinate transformation and derive its trajectory equations, finally we get the equations of worm and gear by using engaged theory. For the Electronic Gear Box (EGB) controller design, the key technologies include synchronous tracking between the leading axis and the following axis which must be considered first in the worm grinding mechanism and the simultaneous motion control between the leading axes accommodated to the gear-shape construction. In this research, we use Matlab to accomplish the simulation of involute gear-shape and 3D motion simulation of gear grindin
