The tooth profile of mismatched worm gear is complex and difficult to manufacture.A a system of the simulation manufacturing of mismatched worm gear is built based on SolidWorks with VB.When simulating manufacturing

the worm gear blank is fixed

the cutter is not only revolute around the axis of itself but also revolute around the axis of the worm gear

put the cutter in the different place

Boolean calculation of reduce between the enveloping solid of the cutter and the worm gear blank

the blank model is replace by the Boolean calculation.Because it is same that the expression of the model and part

the result about virtual manufacturing and the reality manufacturing is match.Assembling the worm wheel and worm

through the sectional view to observe the meshing condition of the worm wheel and worm

the manufacturing parameters are evaluated and adjusted.
