Abstract
This paper develops an integrated CAD/CAM adaptive control
CNC system for milling operations. This research deals with the
integration of the geometric modelling of the product and the control of the
machining operation. The geometric modelling provides a complete
description of part geometries providing its database for the analysis and
manufacturing of the part. The modelling of machining operations develops
a better understanding of the process for control evaluation.
The system contains the automatic generation of NC part program
through CAD and CAM system. CAD system is used to define the
geometry which may be used by a CAM program for tooth path
generation.
Another feature of the system is that it uses the concept of adaptive
control force constraint to overcome the unpredictable changes in the
machining process. These changes may occur in various factors such as
work geometry, material, and tool wear . This concept uses feedrate
manipulation to maintain a specified cutting force in the presence of
varying machining conditions. This requires a model to study the
