Contour compensation method for S-shaped ball-end milling cutter

  • In order to solve the problem of out-of-tolerance profile of the ball-end edge line caused by unfavorable factors such as mechanical error and measurement error during the grinding process of the S-shaped ball-end milling cutter, a profile compensation scheme was proposed. According to the change rule of the contour map of the ball end milling cutter, this scheme inserts several compensation points in the whole section of the ball end contour, adds a radius correction value to the compensation point at the position of the poor contour, and then uses a simple continuous function(or segmented function) to approach the compensation point to ensure smooth connection of the radius values at each compensation point, thereby effectively correcting the contour of the ball end milling cutter and improving the processing quality of the ball end S-shaped edge line.
