精镗加工时,刀尖磨损所造成的工件孔径误差,可以用图1所示尺寸控制系统进行补偿。量头6对已加工孔5进行自动测量,所得数据输入控制装置7。在与给定的调整值比较后作出判断:如需补偿,则由7发出补偿信号给补偿装置4,后者通过镗头使镗刀产生径向微量位移。这样,在加工下一工件时,刀具磨损所造成的工件孔径误差便基本上得到了补偿.采用尺寸控制系统,可使一批工件的孔径分布在公差带中某一尺寸范围内,因此可有效地提高工件的尺寸精度。尺寸控制系统只能补偿刀具磨损所引起的孔径变化,以及精镗长孔时因刀具磨损
Fine boring process, the tip wear caused by the workpiece aperture error, you can use the size control system shown in Figure 1 to compensate. The measuring head 6 automatically measures the machined hole 5 and the resulting data is input into the control device 7. After making a comparison with the given adjustment value: If compensation is required, a compensation signal is issued by 7 to the compensation device 4, which produces a slight radial displacement of the boring tool by the boring head. In this way, when processing the next workpiece, the tool wear caused by the workpiece aperture error will be basically compensated.Using the size control system, a group of workpiece aperture can be distributed in a tolerance within a size range, it is effective To improve the dimensional accuracy of the workpiece. Size control system can only compensate for tool wear caused by the aperture changes, as well as fine bore boring tool wear
