Abstract
The study of the design and manufacturing of special milling processes is important in the development of a mold with complex curved surfaces. In this paper, the analysis method integrates design, manufacturing and numerical simulation to obtain a suitable manufacturing model of the design and NC manufacturing of ball-end cutters. Furthermore, a helical edge curve with constant helix angle on the cylinder and the ball-head, the exact solution of the helical groove cross-section equation, and the mathematical model of the grinding wheel cross-section, are also presented in this study. Results of the numerical simulation and the compensation of NC manufacturing show that the manufacturing of ball-end cutters is capable of being carried out using a two-axis NC machine. These studies provide excellent references for the NC manufacturing of ball-end cutters.
