AI Technical Summary
In existing technologies, repeated disassembly and assembly during the machining of cylindrical gears can lead to errors, and traditional measurement methods are inefficient and difficult to guarantee accuracy.
A calibration-free online measurement method based on polar coordinate machine tools is adopted. The measurement coordinate system of the cylindrical gear is determined by fitting the plane with the least squares method and fitting the cylindrical surface with the particle swarm optimization algorithm. The coordinate system includes the measurement end face point and the tooth tip cylindrical surface point. The intersection point is obtained by solving the simultaneous equations to obtain the measurement coordinate system.
This technology enables measurement without disassembly during the machining process of cylindrical gears, avoiding the reduction in accuracy caused by repeated clamping and improving measurement efficiency and accuracy.
