摘要：
The structural parameters of flank faces of cutting-breaking drill tip were defined, and three coordinate systems were constructed and corresponding transformation matrices were analyzed. The parametric mathematical models of drill tip edge and flank face were established. The motion modes of the grinding wheel were described by the coordinate transformation matrixes. By means of the kinematics principle, the wheel-grinding position and pose algorithm of flank face of cutting-breaking drill tip was proposed based on the workpiece coordinate system in CNC grinding processes. The corresponding program was developed in VC++ environment, and a series of grinding processes and tests were carried out to verify the effectiveness of the proposed algorithm. The measurement results show that the proposed algorithm may ensure the structure precision of the flank faces of cutting-breaking drill tip, adjust the poses of the grinding wheel flexibly. © 2021, China Mechanical Engineering Magazine Office.
