A STRATEGIC CUTTING TOOL MATERIAL FOR CERAMIC MACHINING
Although green ceramic forming to net shape is generally preferred, it is not always possible due to component complexity or other practical limitations. In such cases, green or pre-sintered ceramic machining is often required. Unfortunately, the inherently abrasive characteristics of green and pre-sintered ceramic components can induce rapid wear in conventional cutting tool materials, such as high-speed steel or cemented carbide. Ceramic-like coatings such as titanium nitride (TiN) are sometimes used to counter abrasive wear and extend tool life; however, the hardness of many tool coatings is lower than ...
