Abstract: The kinematic theory of face grinding process on lapping
machines is analysed. By means of pitch point and pitch circles, the
complicated grinding process is converted into two rotations on
condition that center distance is fixed. Two types of path curves and
their relations are analysed, i.e. workpiece against grinding wheel and
grinding wheel against workpiece. The geometrical analyses and
manufacture quality of workpiece are linked with the aid of cutting
velocity, range of rotational angle of cutting traces and derivative of
the rotational angle with respect to time. The optimal path curve and
kinematic parameters are achieved, and these results are correspond to
the experimental results[1].
