Non-instantaneous-pole envelope grinding method of spiral curved surface of superfine milling cutter

The side edge spiral curved surface of a superfine spiral end milling cutter is of a complex structure and is difficult to machine. A traditional grinding method cannot ensure machining accuracy of a part of a long and thin structure. The invention relates to a non-instantaneous-pole envelope grinding method of the spiral curved surface of the superfine milling cutter. When a cutter is ground, the shape and installation angle of a grinding wheel directly affect the shapes of the front corner, the rear corner and a chip groove of the side edge of the superfine milling cutter. The non-instantaneous-pole envelope principle and the homogeneous coordinate transform method are applied, a mathematical model is obtained by sectioning the spiral curved surface end generated by the standard conical grinding wheel in an envelope mode, and the method can be used for analyzing the influence on the geometric angle and the groove shape of the side edge of the superfine milling cutter from the installation angle and shape of the grinding wheel; in the model, the tilt angle of the grinding wheel is larger than the coangle of the spiral angle, the contact area decreases, and grinding force is reduced; the front cutter face, the rear cutter face and the chip groove are ground multiple times in an envelope generating mode, and the accuracy of geometrical parameters of the superfine milling cutter can be ensured. The non-instantaneous-pole envelope grinding method is suitable for accurate machining of superfine spiral structures with the high length-diameter ratio.
