“…The elastic abrasive can be considered hyperelastic, and the contact pressure (Fn) of the workpiece surface is approximately proportional to the cutting depth of the abrasive tool [18]. Since the elastic abrasive steel is elastoplastically deformed when in contact with steel, the contact pressure is proportional to the cutting depth; the contact is replaced with cutting depth [19]. During the surface polishing experiment, Vs reflects the grinding tool speed Wt, Vf reflects the feed rate along the axis and Ap stands for the set cut depth of the abrasive tool.…”

In order to achieve high quality polishing of a M300 mold steel curved surface, an elastic abrasive is introduced in this paper and its polishing parameters are optimized so that the mirror roughness can be achieved. Based on the Preston equation and Hertz Contact Theory, the theoretical material removal rate (MRR) equation for surface polishing of elastic abrasives is obtained. The effects of process parameters on MRR are analyzed and the polishing parameters to be optimized are as follows: particle size (S), rotational speed (Wt), cutting depth (Ap) and feed speed (Vf). The Taguchi method is applied to design the orthogonal experiment with four factors and three levels. The influence degree of various factors on the roughness of the polished surface and the combination of parameters to be optimized were obtained by the signal-to-noise ratio method. The particle swarm optimization algorithm optimized with the back propagation (BP) neural network algorithm (PSO-BP) is used to optimize the polishing parameters. The results show that the rotational speed has the greatest influence on the roughness, the influence degree of abrasive particle size is greater than that of feed speed, and cutting depth has the least influence. The optimum parameters are as follows: particle size (S) = #1200, rotational speed (Wt) = 4500 rpm, cutting depth (Ap) = 0.25 mm and feed speed (Vf) = 0.8 mm/min. The roughness of the surface polishing with optimum parameters is reduced to 0.021 μm.

This article presents the results of experimental studies of forces arising from the interaction of elastic polymer-abrasive wheel with the treated surface. The dependences of normal and tangential components of cutting force on the speed, tool deformation and feed are established. Cutting forces directly influence the removal rate, roughness of the processed surface, temperature in the cutting zone and residual stresses in the surface layer.

The effectiveness of elastic polymer-abrasive wheels when rounding edges has been proved. The research showed the influence of cutting speed, deformation of the tool and feed along the edge on the quality of the machined edge and the productivity of the process. Empirical equations are proposed for calculating the parameters of quality and productivity depending on the processing regime parameters.
