Three-Dimensional Simulation of Machined, Tool Surfaces and Shaping Process with Two-Side Grinding of Cylindrical Parts Ends

Two-side end grinding is widely used for machining end surfaces of various parts. In all methods of two-side end surface grinding, the wheel is aligned with the end surface perpendicular to its axis of rotation. This gives the error of shaping the end surface of the part when turning the wheels. In this research work, the method of two-side end grinding of the parts ends with different diameters, pusher type, valve, and cylindrical parts with the same diameters is proposed, which eliminates the shaping error of the machined end surface. This is achieved by orienting the grinding wheels and sharpening them on a CNC machine. First the tool sharpening is presented to improve the accuracy of the parts end surfaces and can be used in the parts machining not only with different diameters of the end surfaces, but also the same. The high accuracy of the ends is provided due to their roughing the surface of the end of the grinding wheel, and the finishing - by a conical calibration area, which lies in the plane of the machined part end. The research of the method is carried out on the basis of the developed general three-dimensional models of details and the process of shaping. The results of the research show a high accuracy of end surfaces grinding. The developed general three-dimensional models of the parts and shaping of their end surfaces will contribute to the creation of new high-performance two-side end grinding techniques.
