【Abstract】 From the view point of spatial geometry, the transformation theory of the machine setting parameters from cutter tilt milling machines to Free Form milling machines was analyzed, with which a transformation method was developed, and formulas in explicit form were obtained. The precise solutions of coefficients of higher order Taylor expansion of every axis can be derived by means of differentiating the transformation formulas. Thus a rapid response from a computer can be expected. The method introduced here is distinguished from others in both concept and algorithm, It is more direct and simple, and can meet the requirement of real time interpolation of CNC system.更多还原
