Abstract

The invention provides a profile tolerance compensation method of an S-shaped ball-end milling cutter. The profile tolerance compensation method comprises the following steps: selecting a plurality of points needing profile tolerance compensation according to a profile graph of the S-shaped ball-end milling cutter and determining coordinates of the compensation points; selecting a proper interpolation or fitting method to approach the compensation points to obtain a radius transition curve; obtaining a radius corrected value of each grinding point according to the radius transition curve; moving a grinding wheel along a relief angle tangent plane normal direction of the grinding point according to the radius corrected value. The method provided by the invention can be used for effectively controlling the profile tolerance of a ball end and the machining quality of a ball-end S-shaped edge is improved.

Description

technical field [0001] The invention relates to the technical field of ball-end milling cutters, in particular to a method for compensating the contour of an S-shaped ball-end milling cutter. Background technique [0002] Ball end milling cutters are important tools for milling various complex surfaces, especially with the increasing number of CNC machine tools, the demand for such tools will increase day by day. The conventional ball end milling cutter has a straight edge, which is not easy to remove chips during the cutting process. The chips are easy to accumulate near the cutting edge and block the milling cutter, which not only affects the machining accuracy, but also reduces the service life of the tool. At present, most domestically purchased S-shaped ball-end milling cutters made abroad, the rake face is a wave-shaped surface, which is easy to remove chips. Some domestic experts and factories have done a lot of work on the processing mechanism and mathematical model...
