Honing cylindricity prediction method

The invention discloses a honing cylindricity prediction method, which aims at solving the problems that the material removal amount at two ends is small and the middle is large in the machining process, the cylindricity of a honed hole is poor and the like in the constant-pressure honing process, and a honing machining process motion simulation model is constructed by simulating the shape of an oilstone, reconstructing a motion track, calculating the contact area of the oilstone and a workpiece, the honing time and the like; the method comprises the following steps: establishing a honing tool mechanical model, calculating the magnitude of normal force borne by oilstone in the machining process, calculating the cutting depth of each abrasive particle in the honing process according to stress balance, further calculating the material removal amount, exploring the distribution rule of the honing material removal amount, calculating the cylindricity after honing, establishing a honing cylindricity prediction mod
