Abstract
Coating tools have been developed for the purpose of high cutting accuracy, high cutting surface accuracy and extension of tool life now. However, conventional coating tools have a high affinity for ductile materials, like aluminum alloy, so cutting chips tend to adhere to cutting edge and work material surface. Therefore, Chipping causes and surface texture is degraded. In order to solve these problems, recently, DLC (Diamond-Like-Carbon) has been applied to coating material. In this research, it is curried out cutting of Aluminum alloy by the use of DLC coating tool, and examined influence of DLC coating conditions on cutting characteristics. We have proposed that it carried out hydrogen ion bombardment technique for realization of high hardness and low resistance cutting tool. As a result of cutting test by the use of this tool, it is cleared that cutting resistance decreases and surface roughness improves.
