The invention discloses a method for adjusting the position and posture of cutter shafts for
grinding blade-type parts. The method comprises the following steps: 1, a cutter contact coordinate systemxi (L) and a workpiece coordinate
system xi (w) are established, and cutter shaft vectors are expressed in the workpiece coordinate
system as in the specification, wherein in the formula, alpha is a
heel angle of the contact face of a cutter and a workpiece, and beta is a
slip angle of the contact face of the cutter and the workpiece; 2, cutter contacts are discretized, the included angle theta<i,i+1> between the cutter shaft vector of the i cutter contact and the cutter shaft vector of the <i+1> cutter contact is obtained, and the motion angular speed
omega<i, i+1> between the icutter contact and the <i+1> cutter contact is calculated according to the formula; and 3, the optimization target function is established, according to the optimization target function, the cutter shaft vector position and posture meeting the minimum angular speed is solved, and the motion relationship of all the shafts of a
numerical control grinder is solved. The cutter can conduct smooth
machining in the
grinding process, the phenomenon of overcutting or interference at curvature sudden
change positions of the blade-type parts is avoided, and the surface
machining quality is guaranteed.
