Computer aided design of herringbone gear

With the rapid development of CAD technique,the design calculation of mechanical design,check calculation and parameterized drawing technology of design can be done by the way of programming,basing on platform development of AutoCAD.And the way showed the significant advantages of simple program,stable operation and improving the design efficiency.It can accomplish the man-machine dialogue conveniently and also carry on parametric design by the secondary development in the process of design.And it is able to liberate designers from the heavy labor.This article carried on the preliminary discussion about the development of computer aided design system of herringbone gear.
