Special CNC Based on Advanced Controller

This paper introduces a new type of CNC, which is based on Sinumerik 840D and STEP-NC. This is a kernel of I2MS (Intelligent integrated Manufacturing System), which includes compute-aided design, computer aided process plan, computer aided manufacturing, and CNC. It provides them a unified platform oriented to CNC manufacturing, which make their work turned from distributed work to collaborative work. In this paper, we describe and analyze the conceptual framework and key technologies such as AI, KM, and etc systematically. We also discuss STEP-NC approaches using in CNC.
