Abstract：In order to realize the vortex of the evaluation of the precision measuring plate profile,this paper put forward a new method of calculation vortex line profile error according to its detection feature and based on the definition.First of all,getting the actual measuring discrete points of measured contour;Then,computing the extremely radius of a series of practical and theoretical outline of the corresponding points;Finally,calculating corresponding points of the radius error,and madding the second times value as the minimum distance of contain measured outline,it’s vortex line profile error.Calculating 15 000 records used 0.2 s,got the average error of 0.0056 mm,and the precision requirement is far less than 0.01 mm.Using a radius error expression minimum contain distance,the method is simple,feasible,and effectively improve the vortex line profile error calculation,and it’s applicable to the vortex dish measurement and evaluation.
