A biconjugate closed-end cylindrical single-cam pair refer to a cylindrical cam pair that control two roller followers. Based on the theory of space conjugated surface and vector revolving, by analyzing the conjugation relation between two rollers and cam surfaces of a biconjugate closed-end cylindrical single-cam pair, the parameter equations of the moving path of the axis of the left and right rollers that envelope the cam surface are established. Taking the minimum clearance between the roller and cam surfaces as the optimization objective, the parameter equation was optimized by adjusting the coefficient of the parameter equations of the left and right rollers without changing the structural size of the cam pair, and the optimized equation can be directly used as the tool path of cam machining. Finally, the cam was machined by a 5-axis NC machining center, and the optimized effect was verified by measuring the clearance between the work face of the cam and the rollers after the assembly of the cam, swing rods, and other parts. The obtained results showed that the clearance between the work face of cam and rollers were significantly reduced after optimization, indicating that the optimization method of cam is reasonable.

Active measurement technology is used widely in the modern precision-grinding process; currently, however, it is tedious and time consuming to adjust the process parameters of grinding process. This process usually depends on the experience of operators, which directly affects the processing efficiency and intelligent control level. Aiming to optimize these grinding-process parameters, we propose a grey target decision-making method based on the uniform effect measure to realize the intelligent optimization of process parameters. First, we obtain the experimental data of process parameters and evaluation parameters using the orthogonal experimental method, and then we calculate and analyze the degree of relation between process parameters and evaluation parameters based on grey system theory. Then we can obtain the process parameters that have the greatest influence on the workpiece surface roughness, workpiece roundness, and grinding process time. Second, through the proposed grey target decision-making method based on the uniform effect measure, and combined with grey relation analysis, we assign the weights of different evaluation parameters. By optimizing the calculation of multigroup evaluation parameters, we obtain the group of evaluation parameters with the best synthetic effect and identify the optimal combination of parameters to guide production. Through a large number of experimental verifications and analyses, we find that the proposed grinding process parameters optimization method can obtain the best combination of process parameters and can effectively improve processing quality and processing efficiency. The research results provide a theoretical basis for the optimization of grinding process parameters and enhance the intelligent degree of precision grinding.
