加工中心是一种综合加工能力较强的设备,加工中心配备有刀库和自动换刀装置,在加工过程中可以进行自动选刀和换刀,由于每把刀具的长度都是不同的,同时由于刀具的磨损或换刀等其他原因引起刀具长度发生变化,在对被加工零件设置工件坐标系零点(一般为工件的上表面)后,如果更换的刀具比编程时的标准刀具稍长则将使零件产生过切的现象,反之使零件产生欠切的现象。利用数控系统的刀具长度补偿功能,可以不必通过重新调整刀具或重新对刀,而是通过刀具长
Machining center is a comprehensive processing capacity of the equipment, the machining center is equipped with a tool magazine and automatic tool changer, the process can be automatically selected knife and tool change, because each tool length is different, at the same time If the tool length changes due to other reasons such as tool wear or tool change, after setting the zero point of the workpiece coordinate system (usually the upper surface of the workpiece) to the workpiece, if the tool to be replaced is slightly longer than the standard tool during programming So that the phenomenon of over-produced parts, on the contrary to make the parts undercut phenomenon. CNC tool length compensation using the function, you can do not have to re-adjust the tool or re-alignment, but by the tool length
