Abstract:

When cutting tools was grinded in the tool grinding machine,adjustment of the pose of the surface to be ground  involved complicated multi-joint linkage of planes in space, and calculation of the adjustment angle was a problem which was difficult to solve with general method. With the planar displaying method, the image point of the cutter surface for grinding in projective plane was established. This paper presented a method which transformed the rotation of planes in space into the movement of the image points in projective plane, and then used the universal clip to realize pose adjustment of the cutter surface for grinding, and the relevant calculation formulas were given. The sharpening experiments show that the proposed method can easily sharpen the single point tool with different combination of cutting angles.

Key words: planar displaying method, pose adjustment, multi-joint linkage, single point tool, cutter regrinding
