Abstract

The invention discloses a ball cutter compensation method and device applied to stone mill curved surface machining, a terminal and a computer readable storage medium. The ball cutter compensation method comprises the following steps: obtaining a target center point, a first reference point and a second reference point, and building a reference plane passing through the former three points, wherein the target center point is the center position when the ball cutter passes through the to-be-compensated machining point, the first reference point and the second reference point are the center positions, closest to the target center point, of the ball cutter on the adjacent machining paths, and the machining paths where the adjacent machining paths are located are kept adjacent to the machiningpath where the target center point is located; determining a normal vector of the reference plane and an intersection point of the normal vector and the cutting surface of the ball cutter, and solving a path stroke between the intersection point and a machining starting point; and determining a compensation value of the ball cutter according to the path travel and the normal vector. According tothe ball cutter compensation method and device, the terminal and the computer readable storage medium, synchronous compensation on the cutter is achieved, cutter abrasion errors are approximately eliminated, the curved surface machining precision is guaranteed, the service life of the cutter is prolonged, and the cutter cost is reduced.

technical field [0001] The invention belongs to the technical field of numerical control machining, and specifically relates to a ball cutter compensation method, device, terminal and computer-readable storage medium applied to machining curved surfaces of stone mills. Background technique [0002] The curved surface processing of graphite materials generally requires the use of ball cutters. During the machining process, the ball cutter makes point contact with the surface of the graphite material, and the material is cut and removed by the high-speed rotation of the blade.

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
