This document analyses the surface of piston in two aspects, discrete points of axial section profile are fitted by cubic spline tool of MATLAB, interpolate curve after fitting with method of precision linear approximation. Equipartition of cross section profile are done,and through subdivision of points of equipartition,to approach theory contour. the number of divide points must satisfy the request was made, with the principle of the relative movement,in the processing of cross section in an ellipse,detailed analysis the motion of line motor,pointed out how changes the speed and acceleration of workbench.and must satisfy the basic conditions of the line motor to respond to the turning of cross section in an ellipse. On this basis, design a lathe machining CNC system of piston with structure of upper and lower computer, moulding of surface of piston are completed by upper computer, feed drive of X, Z axis and spindle are completed by lower computer, surface of middle-convex and varying piston are processed finally.
