Selection of the number of grinding operations with the specified processing parameters
In the article are shown the variants of solving the problem of providing the specified parameters of surface roughness at the design stage of the structure of the process. It is shown that when developing the route of the technological process of the selected option, first assign the number of operations that provide a given the specified precision, and then the number of finishing operations to ensure the specified parameters of surface roughness. On the example of the analysis of the change in the value of the given costs in the processing of the workpiece with the provision of a specified roughness in two grinding operations, the necessity of applying the principle of dynamic programming in the design of the route of the technological process of processing workpiece with abrasive tools and determine the criterion of efficiency. It is concluded that the development of the grinding processing route should be considered as a complex process dynamic system. This approach will allow us to apply the apparatus of the theory of optimal control of discrete systems to solve technological problems.
