数控系统的刀具半径补偿是在CNC系统内部由计算机自动完成的。在加工过程中,CNC系统控制的是刀具中心的轨迹,为了方便起见,用户总是按零件轮廓编制加工程序,因而为了加工所需的零件轮廓,在进行内轮廓加工时,我们一般采取刀具补偿的建立、刀具补偿的维持以及刀具补偿的取消这三个步骤保证工件的精度。通过刀补可实现工件的粗、精加工。需在编程中注意刀补的合理运用,避免过切现象,使刀补在编程过程中充分发挥其的效能和作用。
CNC tool radius compensation is in the CNC system by the computer automatically completed. During machining, the CNC system controls the tool center’s path. For convenience, the user always compiles the machining program according to the part contour. Therefore, in order to process the required contour of the part, we generally adopt the tool compensation The establishment of the tool compensation to maintain and the elimination of the three tool offsets to ensure the accuracy of the workpiece. Through the knife to achieve the rough workpiece, finishing. Need to pay attention to the rational use of knife compensation in programming, to avoid over-cutting phenomenon, so that the knife in the programming process to give full play to its effectiveness and role.
