Development of advanced NC geometric cutting simulator

Abstract

A NC geometric cutting simulator is widely used software that is able to verify a tool path without real machining process by executing the machined shape check and the interference check between a tool and a work piece during machining. However, current NC machining simulator is only considered for the geometric information of an objective shape and a tool. For this reason, it is difficult to represent cutting load, tool deflection and wear caused by a physical phenomenon. This paper describes about calculation algorithm of cutting load , deflection and wear of tool based on removal volume.
