Definition of the Cutting Tests II

It is critical to know the time of tool use in order to carry out a comparison of results when cutting conditions, workpiece material or type of tool are changed

It is important to have information about the workpiece material used for previous tool wear generation

In general, nothing is specified about the used workpiece material for tool wear generation: if the material is the same as the one for the AE tests or if the tool wear was achieved by machining different types of workpiece materials

Depending on the used material and the cutting conditions, different variations of the tool geometry can occur

The main cause of wear development is the adhesion mechanism, that consists basically in the transfer of small particles from the tool to the chips
