Current cam design practice, based on acceleration curves defined by trigonometric,
polynomial, or spline functions of the rotation angle, yields profiles that require …

A complex cam shape optimization problem is studied to optimize a unique cam mechanism
for a new cam drive engine. First, the optimization problem is defined through analyzing the …

The requirement of high performance machinery demands efficient methods for design and
manufacturing of Cams. Many authors used different techniques for improving design …

This paper proposes design of cam-follower velocity curve by using B-spline polynomials. B-
spline polynomials are smooth curves defined by control points. Curve shape can be …
