A complex-shaped titanium carbonitride (Ti(C, N))-based cermet tool was prepared by microwave sintering. The effects of molding pressure on density distribution and residual stress of green compact, relative density, mechanical properties, and microstructure of the sintered compact tool were studied. The results indicated that a high-performance complex-shaped ceramic tool can be prepared using the combined technology of molding and microwave sintering. The density of the cutting edge was lower than that of the body of the tool. The difference increased first and then decreased with the increase in molding pressure. When the molding pressure was lower than 200 MPa, minimal differences between rake and flank faces with respect to relative density and mechanical properties were noted, while the relative density and mechanical properties of rake face were higher than that of flank face when the molding pressure was higher than 300 MPa. However, excessive molding pressure resulted in cracks within the tool. The optimal molding pressure for preparation of a Ti(C, N)-based cermet tool with three-dimensional breaker was 400 MPa.
