摘要
This paper describes the effects of novel nitriding technique used in various carbide cutting tools. In manufacturing, eco-friendly machining is demanded of late. So far, many kinds of methods were made practical, for example MQL process. Through the development of coating technology, dry cutting process has been used and even now more improvement of tool life is required. Both coated and the non-coated carbide tool were applied with novel nitriding to elongate their tool life. The results show novel nitriding decreased the coated carbide tool wear and improved its tool life 1.4 times longer than non-treated carbide. Similarly, the non-coated carbide tool wear decreased and built-up edge on tool surface reduced. These improvements may be derived from the hardening effect on the binder material within the carbide tools.
