Article Preview

Focus on the accuracy problem in machining process of SK21 NC cam grinder, the precision-machining restriction condition equation and the calculation method of precision NC instruction are deduced. The reversible calculation model from NC instruction to the cam’s outline is given and a software package of error compensation is developed. Many error parameters which include the abrasion of the grinding wheel, load distortion of the grinding wheel axis, rotation precision of the cam axis and movement precision of the worktable are measured through experiments. The finally grinding experiments results show that the cam’s machining accuracy can be improved more than 50% by the error compensation method in this paper.
