Study on a New High Efficiency Lapping Method for Aspheric Surface Workpiece

Recently the aspheric surface's machining is a difficult problem,so a new method was proposed that aspheric surface workpiece was high speed lapped using lapping tool made by means of bending.In this study,the principle of high speed lapping had been presented,the mathematical model for the lapping tool had been established,and the equidistance-curve error of the lapping tool had been analyzed.The experimental results indicate that the forming precision of the lapping tool is high,the surface quality of the workpiece reaches micron grade,furthermore,the aspheric surface workpiece can been machined using this method by lapping,and that it can meet the needs of medium precision of machining the aspheric surface workpiece.The advantages of the method are of the high efficiency and the low cost,and it has a good development and application prospects.
