Design of the Globoidal Cam Mechanism Based on MATLAB and CATIA

摘要

Working profile of Globoidal indexing cam is a complex surface. 2D mechanical drawing is difficult to describe it clearly. With the development of computer technology, the 3D design software such as CATIA, Pro-E, Solidworks, UG/NX, the solid and surface function of them make productions more excellent. Globoidal indexing cam profile equations firstly was studied, the geometric size of the globoidal indexing cam mechanism was calculate, and then use MATLAB to calculate the globoidal indexing cam contour surface 3D coordinates of points, finally completed the three-dimensional modeling of globoidal indexing cam in CATIA.
