The lower pairs were substituted for the higher pairs in order to study the specific properties of the disc cam with the circular profile and the follower attached to the roller.
The mathematical model is studied for optimal design of high precision circular form turning tools. It introduces the major modular functions of CAD/CAM for the turning tools with VB language.
