Polar machinability diagrams - a model to predict the machinability of a work material


  • Jan-Eric Ståhl
  • Mats Andersson

Summary, in English

The article presents a newly developed model for the description and classification of machinability, based on comparison with a reference material. The model illustrates critical machinability properties in a polar diagram with 5 axes and poles. Each axis represents a behaviour or property, i.e. abrasiveness or hardness. The total machinability profile of a work material can then be outlined by grading the 5 different machinability properties. The polar diagram can be correlated to the corresponding tool properties and the cutting data suitable for the material and the process.
