Automatic control of manufacturing processes: A model

A model is proposed for the automatic control of manufacturing processes and the necessary preparations. The model is based on step-by-step implementation of a systematic approach and a feedback mechanism. In automated control, the preparations, involving CAD/CAPP/CAM/PDM systems, are integrated with control of the manufacturing process. The model permits the use of paperless technology based on a 3D model of the part and three important stages in the derivation and analysis of information regarding the operation of the working centers. Subsystems permit monitoring of the equipment and the cutting tool and analysis of product quality so as to formulate corrective measures on the basis of feedback mechanisms.
