Notes:
In order to keep the stability of tool’s removal function, it is required that the anastomosisbe tight between the tool and workpiece surface in Computer-controlled Optical Surfacing (CCOS).In this paper, the influence of tool’s character on anastomosis status is firstly studied. The relationmodel on the ratio of radius to thickness, Young's modulus of the tool, normal asphericity andnormal arc height of workpiece surface is established, and the macroscopical condition of tightanastomosis is derived in aspheric optics machining. According to the microcosmic distribution ofsurface error, the mathematical relation between anastomosis error and removal rate is researched.In the end, the influence rule of anastomosis status on the convergence ratio of residual error isanalyzed in machining zone. Based on the conclusion of machining instance, it is found thatworkpiece material would be fast removed in middle contact zone when the peak value of tool’sremoval function locates in its center position
