THEORETICAL AND EXPERIMENTAL INVESTIGATIONS OF THE PROCESS OF DOUBLE-SIDED GRINDING THE END FACES WITH SKEW AXESOF CYLINDRICAL PARTS, AND CIRCLES WITH CALIBRATED PARTS
Urgency of the research. The developed 3D model first determines the overall performance Qs of processing the two ends of the parts, depending on the coordinate θb throughout the ladder of the contact line L. Target setting. Machine-tool construction, machine-building and bearing industry are widely used cylindrical parts with high-precision end surfaces, the final accuracy of which is provided by finishing operations. Actual scientific researches and issues analysis. In recent studies, the technique of processing end surfaces of cylindri- cal parts with a circular feed into the processing area was considered. Circles without calibrating plots are used, which re- quires a lot of processing to obtain the required precision, which reduces the productivity of grinding. Uninvestigated parts of general matters defining. Study of the productivity of grinding each end, the power, the cutting forces and their influence on the overall performance and accuracy of finishing the ends of round cylindrical parts with cir cles of calibrated sections. The research objective. Development of 3D model of processing performance of each end of the part and total productivity, based on the acquired performance values for determining the required power. The statement of basic materials. For the first time, a total power analysis was performed on the coordinate of the processing θb, which is the sum of the capacities of the simultaneously machined parts. All studies were conducted at a constant angular velocity of the drum = 4.610 / s and the angle corresponds to the processing area θb2 = 650, the processing time is 14 seconds. If the angular velocity of the drum changes, the angle θb2 remains constant, then the processing time will vary. Conclusions. It has been proved for the first time that when two-sided grinding ends, there are two processes simultaneously with different coordinates θb of processing on each end by the cutting forces, removable assumptions, wear of circles, heating temperatures of faces, pleasures of technological systems from circles to ends, instant productivities, and grinding capacities that significantly affect on the total productivity at each end and on the overall performance and accuracy of the processing of the two ends. For the first time, a general methodology of theoretical and experimental On produktyvnyvnosti research, capacity specific and general, specific cutting forces and common on the left and right ends of the parts.
