In order to study the performance of cutting H13 hard steel with Titanium Nitride (TiN) coated cutting tool, cutting tests of H13 hard steel with TiN coated tools are carried out. The influences of cutting parameters on the cutting force, cutting temperature were studied. The wear and breakage mechanism of carbide coated tool wear were analyzed. It is found that cutting speed，depth of cut and feed rate have great influence on the main cutting force Fz and cutting depth resistance Fx, while less effect on feed resistance Fy. Cutting speed has the greatest influence on cutting temperature. Tool rake face has obvious crater wear and the tool tip occurs micro breakage phenomenon, abrasive wear appears on the flank from observed the tool wear. This study results can provide technical support and experimental guidance for optimization of cutting parameters and improvement of tool life in the machining production.
