摘　　要：针对螺杆转子成形磨削中端面截形为离散点数据的情况,应用空间啮合原理建立了螺杆转子齿面加工的数学模型,推导了砂轮回转面和转子螺旋面之间的接触条件式,综合运用三次参数样条函数法、追赶法和fsolve函数,利用MATLAB软件编程计算出了砂轮轴向截形,为砂轮数控修整程序的编制提供了有效数据。With the given discrete points of the screw rotor＇s cross section, a mathematical model of gear machining was built and the contact line equation between the rotor tooth surface and the forming wheel revolving surface was derived based on the meshing theory. The grinding wheel cross-sectional profile which provides the repair trajectory of grinding wheel in screw rotor form grinding was worked out by the MATLAB software with the compositive theories of cubic parameter spline function, chasing method and fsolve function.
