Embodiment Construction
[0013] (1) According to the geometric angle parameters of the helical edge of the micro-milling cutter, the optimal geometry and installation angle of the grinding wheel are designed. Through numerical calculation, the non-instant center envelope of the simulated grinding wheel movement is developed into a helical surface section, and the grinding process is carried out. optimization.
[0014] (2) When the groove is processed, the center of the large end of the grinding wheel moves from the origin position to the initial position C when the x, y, z and w axes move according to the positions in Table 1. The grinding wheel keeps rotating, and the workpiece performs a spiral motion. When the workpiece moves from the initial position to the end position along the u-axis and A-axis, the complete groove can be machined. In Table 1, θs and θf are the change angles of the A-axis rotation when machining the flank groove and the flank, respectively, compared to the machining of the chi...
