Application generator for the control of CNC machines

Computer numerical control (CNC) machines have brought about vast changes in the manufacturing process since their introduction into the engineering environment. The main advantage of CNC control is its flexibility, making small batch production possible as the changeover from manufacture of one type of board to another is much faster than with mechanically or electromechanically controlled systems. In the past these CNC machines have tended to be viewed as individual stand-alone pieces of equipment. However, with the emergence of CIM as a leading technology, it is important that these machines be totally integrated within the factory network. This paper examines two popular hierarchical models used within the context of CIM and describes an application generator which is under development for the control of automated manufacturing equipment.
