Surface Layer States of Worn Uncoated and TiN-Coated WC/Co-Cemented Carbide Cutting Tools after Dry Plain Turning of Carbon Steel
Figure 9
SEM picture of worn uncoated cutting tool in final state (after cutting length of 7084 m) with cutting parameters as follows: m/min, mm/rev, and mm. Due to the high temperatures acting in the cutting zone some evidence is seen for plastic lowering of the cutting edge [9].
