The main objective of the paper is to provide a common environment where the evaluation of a given general order and later composition of work orders, and designation of production resources could be done automatically under the operator's supervision. The model is functionally included into the five level computer-integrated manufacturing (CIM) hierarchy. Functions of the model are plugged into the lower four levels by means of technological database management system that supports main

... ns of information flow, which flows through the backbone of CIM system. CNC stands for computer Numerical Control and been around since the early 1970s.Prior to this. It was called NC, for Numerical Control. While people in most walks of life have never heard of this term, CNC has touched almost every form of manufacturing process in one way or another. If you will be working in manufacturing, it is likely you will be dealing with CNC on a regular basis.
