The Research of the Regularities of the Influence of the Parameters of Grinding a Flat Surface on Its Roughness during Machining a Metal Polymer

The article deals with issues related to the mechanical machining of a flat surface of a metal-polymer workpiece by flat grinding. The article describes an experiment on flat grinding of a workpiece and determines the dependence of surface roughness as the main parameter on the modes of machining, namely, feed and depth of cut. The data collected in the course of the experiment were analyzed and, according to the results of statistical processing of the experimental results, a model of the roughness of a flat metal-polymer surface was developed depending on the modes of abrasive machining. The article presents both a functional model, presented as a function of roughness from the parameters of the depth of cut and feed, and a graphical representation in the form of a surface graph. The graphical roughness model is a great interest for engineers during setting cutting conditions, as it is more visual and simple. Scientists, who research ways to improve the efficiency of the machining process of parts in the design of which a metal-polymer material is used, can use the functional relationship of roughness, this will optimize the technological parameters according to the required optimization criterion.
