The research and development of gear design system based on Web;

Monte Carlo simulation was employed to realize the reliability design of gears,proving that the application of Monte Carle method in gear design is appropriate and feasible.

This paper presents a CAD system for gear design based on intelligent computation in order to minimize the problems brought by uncertainties in the process of gear design.

According to the principle of GB10095 88, the correct concept and expression method about the design tooth profile and the tolerance range are discussed, and problems general existed in the applications are analyzed.

In the light of the tooth design of rake face in CAD for form relieved cutters, the realization procedure and method of modular design for rake face model are put forward, the calculating formula of K r and the coordinating calculating formula of the point after the contour deflection of the workpiece are deduced.
