Abstract

Providing of high accuracy and performance of end surfaces processing is achieved through bilateral face grinding machines. The development of new methods of grinding the ends of parts and their research will help to improve the competitiveness of engineering, automaking, toolmaking and other enterprises of Ukraine. At present there is no general model of tool surface and components generatrix, as well as their continuous description. In addition, there are no processing capacity calculations, tool wear, cutting force and power at bilateral face grinding, which would at the same time take into account the effect of thermal stress of the process and the rigidity of coordinate processing system. The article shows dependences for calculating processing performance, wear of grinding wheels, cutting forces, power and heat flux with coefficients that take into account heat strength and rigidity to coordinate processing system. Coefficient graph that takes into account the effect of detail heating temperature on the value of shear stress and is introduced into the dependence for calculating cutting forces during grinding is built. General model of generatrix of tool surfaces and nonround parts, which are described by means of continuous Heaviside function, is shown. Three-dimensional models of tool surfaces and parts with nonround profile are presented. The above calculation formulas specified processing performance, wear of grinding wheels, cutting forces, capacity and heat flow allow to make the calculation more precise. And given general model generatrix of tool surfaces, workpieces and its continuous description, allows to describe their three-dimensional geometric model
