Face gear on-machine detection method

The invention discloses a face gear on-machine detection method, and belongs to the field of gear measurement. A novel point distribution grid is adopted to carry out on-machine detection on the tooth surface precision of the face gear. The grid is composed of a contact line of a transverse face gear and the slotting cutter and a contact trace of a vertical face gear and a worm grinding wheel. During measurement, after groove alignment of a measuring head and the tooth surface, geometric errors of grid points are measured, error measurement of all the grid points on a single tooth surface is completed according to a planned track, and measured data are processed. According to the measurement method, the measurement grids are planned from the machining angle, and the measurement method has guiding significance on analysis of error generation reasons and reverse trimming. 本发明公开了一种面齿轮在机检测方法，属于齿轮测量领域。采用一种新型的布点网格对面齿轮齿面精度进行在机检测。这种网格由横向的面齿轮与插齿刀的接触线和竖向的面齿轮与蜗杆砂轮的接触迹构成。在测量时经过测头与齿面的对槽后，对网格点的几何误差进行测量，按照规划的轨迹完成对单个齿面上所有网格点
