Processing method of uncentered clamping

Abstract

The invention discloses a processing method of uncentered clamping. The spatial position between program origin and a part body is ensured to be correct in the course of change through displacement compensation of the program origin. The method includes: determining the part center at any position by the aid of an online measurement technology; achieving program origin tracking according to the part center and calculating corresponding offset when the angle of the parts change; performing corresponding compensation on the program origin according to the offset; allowing the program origin compensation value to be automatically compensated into the program to complete subsequent processing. With the method, the parts can be optionally placed on a workbench if only basic holes are ensured tobe nearby forward direction of the Z axis, fixing and pressing of the parts on the workbench is completed for further processing, machine tool utilization rate is directly improved, artificial participation is lowered, and human error factors are eliminated.

Description

technical field [0001] The invention relates to a mechanical manufacturing technology, in particular to a processing method of non-centering clamping. Background technique [0002] Most of the large-scale CNC machining centers are produced in big manufacturing countries, and the machine tools are equipped with various cutting-edge processing modules. At this stage, factories rarely use these cutting-edge processing modules, which is a great waste for processing equipment; The processing must ensure that the center of rotation of the part and the center of the worktable are completely coincident before the processing can be completed. If there is no coincidence, there will be a displacement deviation between the part body and the origin of the program during the rotation of the part, which will cause all the processing programs to fail and cause the part to be out of tolerance. Therefore, clamping The limitations are extremely high, and the clamping effect is extremely high. ...
