The authors of the article justify the expediency of applying resource saving in developing innovative technologies for hot rolling of boning knife blades from steel slabs. Such knives are widely used in meat processing industry. Metal consumption of the process was significantly reduced after changing the existing factory technology of making boning knives. The operation of cutting or grinding was replaced by hot rolling. The specific feature of the technology lies in minimizing the metal loss into shavings during the final processing of the steel slab by means of cutting. Reducing metal loss in making such steel parts and raising metal utilization rate are achieved by maximum possible approximation of forging configuration to the end product contour and preservation of the allowances regulated by the operational chart. The authors suggest optimal combinations of basic parameters of introduction of resource saving technology into production. To adduce an example the authors justify the possibility of shaping and simultaneous hardening of the knife blade during hot rolling between deforming rollers. Energy intensity of the technology suggested is lowered by means of reducing the time for further mechanic processing of the forging by cutting. Practical approbation of the introduced resource saving technology in repair production made it possible to raise the metal utilization rate to 95% and to reduce by 1.2 the production cost of a boning knife as the end product. When manufacturing the parts metal resources are saved due to the fact that irreversible loss of metal in the innovative technology of the boning knives’ production differs a lot from that in the traditional one. Technical and economic calculations adduced in the article show the effectiveness of the research and prove the profit of implementation of the new technology
