 Abstract

NC(numerical control)machining tools have high productive efficiency, machining quality and flexibility which make them popularize rapidly, and how to guarantee the validity of NC codes has become an outstanding problem in the NC machining process. With the development and application of Virtual manufacturing technology, simulation technology has been widely used in the assessment process plans and equipments for the manufacturing, as well as new product design, and effectively solved the problems in the process of CNC machining. 

This paper will use the Edgecam, VERICUT software, generating the NC program, creating a five axis milling virtual machining center, to conduct the simulation of the NC machining process system of crankshaft. The development of the system includes the CNC programming and NC machining simulation. CNC programming is the use of Edgecam to carry out the tool path editing on workpiece, and getting the NC program through after treatment; NC machining simulation is established virtual machine (including machine tool, fixture, tool spindle head, cutter chain) by using VERICUT, loading the workpiece blank, building tool library, developing numerical control system, importing NC program, and debugging so that the machine can realize the simulation. 

Key words: NC machining simulation; VERICUT; Five-axis milling and turning machining centers; Automatic Programming
