It was fully introduced of the implementation method of automatic honing machining in details, including online measurement, longstroke honing machining, and shortstroke machining of functions integrated in unity. In the honing machining process, the pore sizes were obtained in the computer numerical control (CNC) system by the sensor, which helped to analyze the parameters for honing machining accordingly. By the combination and information exchange of G codes, programmable logical controller (PLC) and background programs, the honing machine will implement the honing work fully and automatically with dual feed of coarse and fine honing, and honing pressure control.
