Open publisher page 0 citations

Abstract

Tool path is automatically generated by the milling numerical control(NC)system based on STEP-NC(STEP Compliant Data Interface for Numerical Control).For demonstrating the correctness of tool path to avoid failure in the practical machining such as collision and interference of the tool,the tool path should be simulated before machining in STEP-NC milling NC system.The machining simulation system is developed in the Visual C++ environment combined with OpenGL graphics library function modules.The modeling method of workpiece and tool in the machining simulation process is presented,The material removal through dynamics intersecting of workpieces and tools is displayed,and simulating machining process in the reality are illustrated.
