Problems solved by technology

Ball cutters wear as machining progresses, negatively impacting surface machining accuracy
[0003] At present, the research on ball cutter compensation in graphite curved surface processing is not enough. Usually, the method of changing the cutter is used to keep the cutter in an ideal surface state and ensure the machining accuracy.
Tool replacement is time-consuming and labor-intensive, and recalibration and adjustment are required after the replacement, and there is an irreversible positioning deviation in the position of the blade before and after the tool change, which makes the surface to be processed discontinuous and the machining accuracy is difficult to guarantee
At the same time, the ball cutter is expensive, and the frequent replacement of the cutter makes the processing cost high

Description

technical field [0001] The invention belongs to the technical field of numerical control machining, and specifically relates to a ball cutter compensation method, a device, a terminal and a computer-readable storage medium applied to the machining of a stone-grinding surface. Background technique [0002] The surface processing of graphite materials generally needs to be realized with the help of ball cutters. During the machining process, the ball cutter is in point contact with the surface of the graphite material, and the material is removed by high-speed rotation of the blade. As machining progresses, ball cutters wear out, negatively affecting surface machining accuracy. [0003] At present, the research on ball-knife compensation in graphite surface machining is still insufficient. Usually, the tool is replaced to keep the tool in the ideal surface state and ensure the machining accuracy. Tool replacement is time-consuming and labor-intensive, and needs to be re-cali...
