Abstract

Grinding processes are usually set up experimentally, product-specifically and iteratively. The selected parameters are often based on empirical values, whereby the user can set very different parameters and achieve similar results.

In 2017, the so called “grinding process validation approach” (gPVA) was introduced to determine suitable parameter windows. The method allows the definition of parameter windows for grinding tools and materials. Parameter adjustments for optimum results are possible due to the experimentally determined dependence on specific chip volume and tool pressure.

The system was originally developed to describe brittle grinding processes on standard grinding machines. Tests on an ultra-precision lathe provide process parameter data on ductile mode machining of tungsten carbide using UPM machines. This paper reports on gPVA being applied to transfer the ductile machining process from UPM machineries to a standard CNC grinding machine.
