difficult-to-cut materials

The possibility of increasing productivity by increasing the cutting parameters of difficult-to-machine materials, using expensive tool materials, etc. is an extensive trend of innovative improvement and is accompanied by high costs of operations and the need to provide expensive equipment. The article argues that a more effective method of improving machining operations is the use of the workpiece Turning with Preventive Heating (TPH) method.

Machining difficult-to-cut materials, which include most high-alloy chromium-nickel steels and alloys, requires optimization of cutting parameters, correct application of tool materials, cutting blade geometry, etc. The particular relevance of a scientifically based analysis in addressing these issues is due to the large costs incurred in machining products made from such materials. The possibilities of experimental research to provide correct technological recommendations are quite limited.
