Optical free form surfaces can be empolyed to realize some special imaging effects and supply more degree of design freedom. These free-form surfaces can be manufactured by compute controlled fabrication (CCF) method on low accuracy machine tool. The profile measurement studied is a key factor that determines the finish accuracy of the optical free-form surfaces in CCF
especially the coordination measuring method. Rapid coordinate measuring method (RCMM) is proposed with case study. Results indicate that measruing time can be largely reduced by RCMM
