The competition in the processing market of the domestic machinery parts has been getting intensified along with the economic development. First, corporations are demanding aggressive activities of production cost reduction for the sake of survival rather than profit generation. Such issues as production process, production time reduction, multi-functional structural change of possessed machinery, eco- friendly process development, etc. are emerging as imminent tasks. To resolve such issues, a variety of research theses from various perspectives have been published. The problem is the diversification of the parts processing method. In other words, it is the multi-kinds & small-scale production method. In the past, there had been an attempt to increase competitiveness through the non-cutting issues such as tool preparation time, tool replacement time, etc.; however, the time spent on the cutting process has been prolonged in recent days. Thus, there has been a demand for a direct solution as to the processing process, and the processing method by hard turning is being presented as the solution. This study analyzed the correlation of cutting force, tool abrasion, surface profile in accordance with the processing conditions using SKD11 in order to determine the optimal conditions at hard turning.
