Requirements and potential for high performance cutting tools based on superhard phases in new applications


  • Jan-Eric Ståhl

Summary, in English

This work covers qualitative and quantitative requirements with regard to material properties
for cutting tools to be able to resist and balance the various interactive mechanisms that cause
the wear of the cutting edge and put limits its tool life. In metal cutting, tool life T combined
with the cutting data (cutting speed, feed and depth of cut) controls largely the manufacturing
cost and related competitiveness. Selected cutting data determine the required tool engagement
time ti in a particular application, and thus have a direct influence on the manufacturing cost.
The selected cutting data in a specific application result in a certain tool life with a statistic
distribution. For example, Colding equation can be used to determine the link between tool life
T and selected cutting data. The tool-cost and its influence on the final cost of manufacturing
of a component is determined mainly by the tool performance, i.e. how high are the cutting
data (Metal Removal Rate) that can be used for a given tool life T.
