Technological improvement in repair service in mining is possible through application of the automated process design system in worn-part reclamation for mining machines. Developed of single processes of worn-part reclamation is a multivariant problem the solution of which provides an industrial engineer with exhaustive information on the methods of repair depending on the type and rate of damage, processes to fit each method, equipment, fittings, tools and standards. Selection of an efficient variant under conditions of a specific production is a heavy workload. In connection with this, this article substantiates application of the automated process design to creating repair documentation at high quality and at the earliest possible date. The automated process design principles suitable for repair service are discussed. It is shown that automated process design can use ready-made project solutions and variant types in machine repair. The sequence of process procedures in part repair process design based on analog processes and conventional unit operations is shown. The article presents a fragment of a conventional unified process of spline shaft reclamation including all possible variants of repair of different surfaces of the part, such as diametrally opposite surfaces, spline and slot surfaces, and thread surfaces. This process is a reference in the automated process design for reclamation of spline shafts. The process routes of worn-part reclamation are developed with regard to the purpose of a part, structural features, rate of wear, and using both conventional and advanced methods of repair. The proposed process routes can used in development of a one fault-at-a time reconditioning technology, technology for a package of defects and a group technology for shaft repair.
