Mathematical modeling on a novel manufacturing method for roller-gear cams using a whirl-machining process

The whirl-machining process is a precise, efficient, and promising machine for manufacturing workpieces over the milling process. At same time, roller-gear cam has advantages other cam-follower system. However, not been applied to manufacture cam. Therefore, this paper proposes novel method using Mathematical modeling described generating cam, roller, whirl-milling tool surface. A CNC its coordinate system are proposed. Cutting simulations obtaining surface topologies normal deviations conducted. Globoidal with different cylindrical rollers, globoidal conical roller taken as case studies, results discussed. virtual cutting simulation was conducted VERICUT. Some machining examples shown verify benefits of proposed in manufacturing.
