Abstract: This article presents a polar diagram method developed for describing and evaluating the potential machinability of different workpiece materials. The potential machinability is examined in terms of five critical properties of the workpiece material. Two groups of materials, a group of common steel grades and the other a group of stainless steels, were examined in detail, their polar diagrams illustrating the potential for comparing the machinability of different workpiece materials. Polar diagrams are seen as being particularly helpful in setup work for the machining of new, previously unknown materials as it allows for comparison with other materials and their respective machinability.
Keywords: polar diagrams; machinability; workpiece materials; material properties; cutting data.
