A CAM program for forming design Automated of CAM for Spring using car was developed in this study. This program was written in AUTO LISP on the AUTO CAD system with a personal. An approach to the system is based on the kinemateic of the object function. We make a determination of an cam programming. A CAM spline is continuous in displacement. velocity and acceleration. This program which can design Coil Spring shapes will successfully support CAN designing and manufacturing for Small & Medium companies.
