TOOL LIFE AND WEAR MODEL IN METAL CUTTING, PART 1 - INFLUENCE OF VARYING FLANK WEAR CRITERION ON COLDING’S TOOL LIFE EQUATION
Last modified: 2014-12-08
Abstract
The tool life model formulated by Bertil Colding is limited to the use of a specified tool life criterion. The Colding equation describes the relationship between tool life, cutting speed and the equivalent chip thickness. The Colding equation is based on five constants which have unique values for each selected value of the tool life criterion. This paper investigates how these Colding constants can vary for different selected wear criteria.
