The paper investigates the process of electroerosive diamond grinding by changing the polarity of electrodes in time in the cutting zone for processing various materials, and the distance between the grains is determined. The study aims to determine the effect on the distance between the grains of the electrical modes of electrical discharge grinding (ED grinding) and the characteristics of the wheel using the mathematical method of planning experiments. The planning of the experiment gave the result with the smallest error and made it possible to minimize the number of experiments. As a result of experimental studies, a mathematical model of the distance between grains has been constructed. This model considers the electrical process modes and the wheel characteristics. For various values of electrical modes and the wheel characteristics, using the functional dependence, it is possible to determine the distance between the grains. It was found that the most significant factors that affect the distance between grains are the frequency and relative pulse duration, grain size, and concentration of diamond wheels. The study results obtained allow using the functional dependence to calculate the grinding process's productivity, assess the cutting ability, and simulate the wear of the wheels without lengthy and expensive experimental studies.

Abstract. The issues of the influence of orientation and the shape of abrasive grains on one of their most important operational characteristicscutting ability, and also on cutting properties of tools made of them, are considered in the article. Modern approaches to cutting capacity assessment, of both single grains, and loose abrasive mass are analyzed. The original method for the assessment of cutting capacity of a single grinding grain fixed in a rotating disk, implemented in surface grinding, is presented. The experimental data of the dependence of the cutting capacity on the shape and the orientation angle of the grinding grains are presented. In addition, the influence of the shape factor of the flap grinding wheel grains on its cutting capacity is shown. Practical recommendations on the application in practice of various varieties of grinding grains are proposed.

The work is devoted to study of profilograph features for determining geometric characteristics of products by laser scanning. The control methods applied are implemented in science-based designs of technical means of control that can provide high accuracy of parameter measurement when profiling the surface of parts. The analysis of graphs of the metal sheet surface in full and Cartesian coordinates made it possible to determine the highest and lowest points of the surface, therefore to determine the profile of sheet undulation. For example, the height of metal sheet irregularities resulted from some deformations was 6,378 mm.
