Abstract
An adaptive feedrate control and method of optimizing the metal removal rate of NC end milling is based on a solid modeler which continuously simulates the in-process workpiece geometry in 3-dimensional machining. For each NC record representing a tool motion, an adjusted feedrate is generated off-line by the simulation running on a general purpose computer. The metal removal rate, cutting force, and tool deflection are calculated, and a feedrate is chosen to increase machine utilization without violating user-set constraints and avoid common machine problems such as excessive tool deflection and tool breakage.
