Selected Aspects of Precision Grinding Processes Optimization

Abstract

The paper describes selected aspects of the optimization of grinding processes, taking into account the characteristic probabilistic features of this process. Characteristic features of the grinding process that influence the significant dispersion of the quantities used in the optimization process to define goals and limitations are indicated. Attention was paid to the reasons for uncertainty in the use of research results, imperfections in information extraction procedures and the limited amount of data in the use of simulation and regression models in optimization procedures. The issue of determining the durability of abrasive tools in grinding process optimization procedures was analyzed. Methodologies for defining tool life are specified, taking into account the dispersion of the values of controlled process parameters. The effects of interference were taken into account in the relationships describing grinding efficiency and costs. The benefits of optimization taking into account the probabilistic nature of the process were determined.

“…Moreover, numerous microporous structures, which create micro-edges, are produced on its surface. On the one hand, when the workpiece material is ground by this grit type, the undeformed chip thickness decreases dramatically due to the increase in the micro-cutting edges, which allow for hard and brittle materials to be removed mainly in a plastic form, reducing the subsurface damage caused by stress concentration [ 9 , 10 ]. On the other hand, the grit produces microporous fragmentation during the grinding process, forming new micro-edges, which improve the grinding efficiency.…”
