Determination of the effective cutting speed of a prefabricated tool based on an assessment of the risks of low machinability of the material and loss of operability of the cutting tool

The article provides a method for determining the effective cutting speed as a result of using the previously developed method of assessing risks and opportunities in the operation of prefabricated cutting tools, which allowed to identify the risks of low machinability of the material and loss of operability of the cutting tool. These risks have been assessed for a specific technological operation. As a result of the implementation of the method, the most suitable tool hard alloy was selected, rational cutting modes were selected based on an assessment of the risk of low machinability of the material and the risk of loss of operability of the cutting tool.
