The invention discloses a worm
grinding wheel point finishing method for simplifying track point input. The worm
grinding wheel point finishing method comprises the following steps that firstly, slotting cutter design parameters consistent with the normal section of a worm
grinding wheel are deduced; 2, establishing a slotting cutter
tooth surface equation, and solving a contact point of a point finishing wheel and a worm
grinding wheel to obtain a point finishing track point; 3, establishing a theoretical motion relation between the point finishing wheel and the worm
grinding wheel, and deducing a theoretical
transformation matrix; 4, based on a
machine tool
kinematic chain, the actual motion relation between the point finishing wheel and the worm
grinding wheel is established, and an actual
transformation matrix is deduced; 5, the theoretical
transformation matrix and the actual transformation matrix are combined, and a linkage relational expression of all shafts of the
machine tool is solved; and 6, the
machine tool is guided to execute finishing operation based on the linkage relational expression, the point finishing track points are only input once during first-time finishing, the problem that track control points need to be input for multiple times during multiple times of point finishing is solved, the operation efficiency of multiple times of point finishing can be remarkably improved, and the sand contour precision after finishing can be ensured.
