针对典型四轴零件加工案例,通过圆柱凸轮表面凹槽轮廓进行数理分析,得出轮廓加工点坐标间的关联特点,并建立联系方程,利用变量设置完成宏程序的编程。通过案例曲线轮廓,推广至二次曲线轮廓四轴加工均可采用此方式进行分析和编程。简述了VERICUT仿真软件特点及仿真过程注意事项,并利用该软件对编写的宏程序进行了仿真验证,程序虚拟加工过程效果良好。
Aiming at the processing of typical four-axis parts, the mathematical analysis of the profile of the groove on the surface of the cylindrical cam was carried out, and the correlation between the coordinates of the contouring points was obtained. The connection equations were established and the programming of the macro program was completed by setting the variables. Through the curve of case curve, it can be analyzed and programmed in this way to extend to quadric curve contour four-axis machining. The characteristics of VERICUT simulation software and the precautions of the simulation process are briefly described. By using this software, the simulation of the prepared macro program is validated, and the virtual processing of the program works well.
