CAP与宏程序手工编程在实际加工中的对比研究

Comparision of CAP and manual macro programming in actual manufacturing process

针对数控加工中计算机辅助编程(CAP)越来越普及而手工编程逐渐被忽略的问题,在数控机床的实际加工应用中对两种编程方式的加工效果进行了验证和比较。找出了两种编程方法在原理上存在的差异性,对5种程序通信方式的应用过程和结果进行了比较及评价,以半球铣削加工和螺旋铣削内圆孔加工为例进行了工艺分析和实例验证,讨论了采用CAD/CAM软件对编程进行优化的具体方法,最后得出了两种编程方式在应用中的优势与缺陷,以寻找两者在实际应用中最适合的载体。研究结果表明:通过熟练掌握手工编程,灵活地运用宏程序,也能在实际的加工应用中编出短小、精悍而加工精度能与计算机辅助编程相媲美的程序。

Aiming that the computer aided programming （CAP） is becoming increasingly popular, but the manual macro programming is gradually neglected during the CNC manufacturing process, the effects by applying these two programming methods into actual CNC manufacturing process were verified and compared. The differences of these two programming methods in principle were identified and L the results of five types of programming communication way in the actual application were compared and evaluated. Through examples of the hemisphere milling and inside-hole helical milling processing, the process analysis and example verification were conducted and the concrete methods of CAD/CAM software optimizing the programming were discussed. Finally, the advantages and disadvantages of these two programming methods were concluded to find out the way which is most suitable for these two programming methods. The experimental results indicate that skillfully mastering the manual macro programming and flexibly applying it can help to compile the compact and accurate programming code, the manufacturing tolerance can even compete with that of the computer-aided programming.
