Traditional offset method can not directly generate the cutter-location surface of measured data with defects.Thus,a tolerance method of cutter-location surface generation was proposed based on MLS fitness.Firstly,the measured data were transformed to a swelling ball model by the length of ball-end cutter's radius.Secondly,according to the geometric principle of convex hull,outer envelope data of this swelling ball model were acquired.Finally,local MLS projection fitting method was used to eliminate possibl...
