基于FANUC数控系统的坐标系自动补偿的研究和应用
摘要
FANUC数控加工中心机床在加工零件时,经常会遇到下面的这种问题:由于零件加工部位的需要,通常要求工作台能旋转任意角度。当工件坐标系原点与工作台的旋转中心重合时,工作台的旋转不会给加工过程带来影响。但在一般情况下件坐标系原点与工作台的旋转中心是不重合的,工件坐标系原点的位置随着工作台的旋转,在机床坐标系中发生变化。所以,要求重新设定工件坐标系原点的位置。在实际生产中通常的做法是,借助于计算机,根据旋转角度计算出工件坐标系原点的变化量,在初始工件坐标原点设定值的基础上进行补偿计算,然后人工设定新的工件坐标系原点的位置。这种人工补偿计算,设定的方法不仅效率低,而且容易出现错误。
本文运用FANUC系统中的宏指令及参变量,提出了编写一个补偿软件,认为此程序可以实现数控加工中心机床在零件过程中,工作台任意角度旋转后,自动补偿与并设定新的工件坐标系原点的位置。

Abstract
C system based on the coordinates of the research and application of pensation
C processing center machine, often in ponents will meet the following this question: because parts processing parts of the need, usually require workbench can rotate arbitrary Angle. When the workpiece axis of rotation center coincides with table, the rotation of the workbench impact won't give processing. But normally a axis and workbench the rotation center is not coincidence, workpiece axis position with the rotation of the workbench, changes in the machine tool coordinate system. So, asked to set workpiece axis position. In the actual production of typically, computer, according to the rotation Angle by calculating the changes needed a axis, in the initial amount of workpiece coordinates value based on the origin, pensate calculation manually set new self-positioning presended in the position of origin. This pensation calculation, the method is not only set low efficiency, and prone to errors. This paper USES the macro instruction and FANUC system, puts forward the parameter write pensation software, think this program can achieve nc machining center machine in parts processing process, workbench arbitrary Angle rotation, pensation and and setting new workpiece axis position
