数控程序模块化设计在滚齿加工中的应用

The Application of NC Program Modular Design in Hobbing

沈冶公司搬迁升级后,机加设备数控化比率达到了65%,如何提高机加设备的生产效率,成为数控技术人员研究的课题。提高数控设备加工效率中很关键的一项是提高数控编程效率,减少辅助时间。对齿轮滚齿加工原理、数控滚齿机及齿轮加工刀具的特性进行了深入的研究,尽管齿轮及切削刀具种类繁多,轮廓曲线颇为复杂,但是因其形状有一定规律性,参数具有有限性,因此程序编制具有相同性,可将其进行模块化。在齿轮加工主程序的设计中将齿轮、刀具参数及啮合关系通过R参数和高级编程语句将其赋值,然后通过数控系统自行计算其啮合关系及循环加工关系,形成数控编程模块化。在加工同类产品时无需再编制主程序,只需改变相应的R参数赋值。大大的降低了劳动强度,节省了编程时间,减少了加工辅助时间,提高了生产效率。

After our company's moving and upgrading,the CNC ratio of machine equipment has reached 65%.How to improve the production efficiency of the equipment has become the subject of numerical control technology researchers.The key to improve the machining efficiency of NC equipment is to improve the efficiency of NC programming and reduce the auxiliary time.The characteristics of gear hobbing and gear machining principle of CNC gear hobbing machine and gear cutting tool are studied,while the gear cutting tool and variety,the contour curve is quite complex,but because its shape has a certain regularity,the parameter is limited,so the program has the same system,the module of.In the main program design,gear cutting,gear cutter parameters and meshing between the R parameters and advanced programming statement to its assignment,and then through the numerical control system to calculate its own engagement and circulation processing,the formation of NC programming module.In the processing of similar products,there is no need to compile the main program,just change the corresponding R parameter assignment.The labor intensity is greatly reduced,the programming time is saved,the processing auxiliary time is reduced,and the production efficiency is improved.
