The Influence of ProcessVariables for MillingSculptured Surfaces on Surface Roughness

Increasing the variety of products that are being designed with sculptured surfaces, efficient machining of these surfaces has become more important in many manufacturing industries. The objective of the present work is the investigation of milling parameters for the sculptured surfacesthat effectin...
