The aim of this paper is to find the evaluate method for straightness error conforms to the smallest condition. First, the algorithm model and the realization method of evaluating straightness error in two spot, least squares method and the minimum envelope zone method have been introduced in detail. The experiment data of eight different kinds of straights have been done on CMM. Then the measured data are evaluated by two spot, least square method and minimum envelope zone method based on search approximatioss(namely cut and try method in revolutionally). It´s the experimental result indicated that minimum envelope zone method based on search approximatioss evaluates the result precision to be the highest, and conform to the smallest condition. the sampling distribution impacts the evaluating precision of two spot and least squares method.
