The Issues of Improving Surfaces Quality and Productivity in the Grinding with the Copy Method for Shaped and Tooth Surfaces

Abstract

In the grinding of machine and responsible equipment parts, gear surfaces with various purpose shapes provided in the construction of tools, as well as gear surfaces, provide high processing accuracy and productivity. At this time, the positioning angles of the elemental regions of the workpiece to be ground in the cutting zone differ from each other, and the actual cutting depth varies along the shaped profile. Due to inheritance, similar processing errors occur on the ground surface, and processing efficiency is not ensured. In this work, the mechanism of the change in cutting depth during the grinding of shaped surfaces by copying is investigated, the direction of ensuring its maximum regularity along the shaped profile is determined, and the issue of improving the quality and efficiency of grinding is solved by using the technological possibilities of operation. Despite the reduction in the number of working trips, grinding should be carried out in relatively light modes, and it is possible to ensure similar grinding quality. By placing the tooth of the gear to be ground at an angle, the roughness of the processed surfaces during grinding is smaller than that of the tooth grinding with the existing method, and the quality is correspondingly high.
