Conditions of reduced cost for machine-building products

Abstract

The mathematical model for the cost of processing of machine parts was developed and the conditions for its reduction were determined. Analytically established the existence of a minimum of the cost of processing which achieved at high cutting speeds in terms of using modern high-performance cutting tools with wear-resistant coatings and high-speed machining centers with CNC. This opens up wide possibilities for the effective application in practice of high-performance high-speed processing and, on this basis, for reduction in the cost of machine-building products. It is shown that the optimal durability of the cutting tool which determines the minimum cost of processing depends only on the economic parameters. This indicates the need to solve technological problems associated with the mechanical treatment of machine parts through the use of economic methods. The specific practical recommendations for the improvement of engineering technology are given.
