Research on tracing measurement method for non-circular contour plays an important role in the realization of high-precision and high-efficiency detection for crankshaft, camshaft and other complex shafts. Tracing measurement scheme is designed for detection of complex shafts non-circular contour surface. After setting workpiece coordinate by head and tail ring gauge, relative position calibration method between the rotation center and the top center is proposed. The system error calculation model of the measuring device is established which is not parallel to the rotation axis when moving along the axis of the workpiece. The position of the base circle least square center is optimized to realize cam eccentricity correction based on the rotation angle and radial dimension of the base circle area. Cam lift error evaluation model is established with combination of sensitive point method and least-square method. The influence on cam lift error evaluation with radial measurement device installation error and top center positioning error are studied by simulation. Contrast test is conducted between SE13-J10 tracing measuring instrument and ADCOLE 1200SH crankshaft camshaft special measuring instrument. The experimental research shows that the cam size, shape and error measurement accuracy and repeatability meet the high precision measurement requirements of the shaft parts. It is proved that the correctness of tracing measurement scheme and the cam lift error evaluation model.
