数控机床不直接受人的控制,而是受程序控制,学生在实习时往往会将程序编错、输错、改错,这都会造成撞刀等设备事故。一旦发生撞刀事故,机床精度将会降低。因此,数控专业实习教学中的人身及设备安全问题就显得尤为重要。本文主要从数控程序的优化,编程技巧等方面介绍了一些在学生实训中预防事故的方法。 CNC machine tools are not directly under the control of the people, but by program control, students often in the internship program will be wrong, wrong, error correction, which will cause the collision knife and other equipment accidents. In the event of a collision knife, machine accuracy will be reduced. Therefore, the NC professional practice teaching personal and equipment safety issues are particularly important. This article mainly introduces some methods of accident prevention in student training from the aspects of optimization of NC programs, programming skills and so on.
