This article discusses the main aspects related to the software of the automated system «Lineika». The main function of the CAM «Lineika» is to assess the predictive complexity and cost of manufacturing parts and products of tool production. The system provides an automated calculation of the above technical and economic indicators for the following groups of class 28, allocated by regulatory documents: cutting tool; measuring tool; appliances, dies, moulds, production accessories. Approbation of the created automated system in real production conditions showed the high efficiency of the proposed engineering method of rationing in the calculation of the projected intensity of the production of cutting, measuring tools, as well as forming parts of tooling. Its introduction into the pilot production of the development of new products will significantly reduce the time required for the development of new device designs for manufacturability, which in general will reduce the final cost of production.
