Abstract
A PC-based virtual machining simulator has been developed to evaluate the m achining operation performed by the NC program in the process planning stag e. The virtual machining simulator consists of an NC program simulator, a g eometric simulator and a physical simulator. The NC program simulator can c alculate the CL (Cutter Location) data and operational time and detect cutt ing conditions such as feed rate and spindle speed by interpreting the NC p rogram. The geometric simulator demonstrates the machining process and dete cts implicit cutting conditions such as depths of cut and metal removal rat e. The physical simulator estimates the instantaneous cutting force and mac hining error based on the cutting models. Process planners easily recognize the problem in NC programs and evaluate machining accuracy before the real machining operation using these estimated results. It is easy to understan d the differences in the operational time, cutting force and machining accu racy of two NC programs based on their case studies.
