Design of engineering processes for manufacturing and repair of parts with wear-resistant coatings
A computation procedure is developed allowing the definition of inter-operation dimensions and allowances for machining coating applied and also the definition of the route for basic material machining and the substantiation of the parts group formation according to design-technological signs and repair dimensions. In the paper there shown procedures for the computation of coating thickness depending on parts wear. There is developed a circuit to the computation of a coating residual layer. An expression for the computation of coating thickness is obtained. Theoretical dependences and computation procedures are obtained that allows solving the whole problem complex arising at the dimension analysis of engineering processes of manufacturing parts with coatings.
