Choice of the Effective Tool Material Proceeding from the Scribing Trace Parameters

Abstract

Determination of the operational properties of the metal-cutting tool through actual-service test is undesirable on virtue of long-duration and expensiveness of the testing procedure, especially when several tool materials to be compared are available in production or under development. Indirect methods of nondestructive control can provide a possibility of rapid (time-efficient) forecasting of the service properties or qualitative ranking of the materials to be compared by a certain service parameter. We have a good reason to believe that a method of pendulum scribing that comes most close (among all indentation-based procedures) to real conditions of tool loading upon cutting makes possible to get a trace on the sample or on the real tool resulting from interaction of the indenter with the studied material. The trace parametes can be considered a quantitative characteristic of the processes proceeding upon the specified interaction and can be used for forecasting of the operational properties of the tool material.
