Notes:
An arc envelope grinding method for non-axisymmetric aspheric surface was proposed inorder to achieve the mould core used for the precision injection molding of optic reflector. Ingrinding, the arc-shaped diamond grinding wheel trued on CNC grinder was used to envelopeworkpiece and generate curve surface, and the spacing distance between tool paths is controlled by theequal-envelope height between wheel and workpiece. In this paper, arc envelope grinding principlewas investigated in connection with wheel coordinate calculation and tool path number. Thetheoretical analysis and grinding experiment showed that arc envelope grinding may improve formgrinding efficiency especially for large curvature and smoothness of ground surface and a smoothcurve surface can be produced when the equal-envelope height is less than a certain value
