Abstract
The control actions prescribed in adaptive control machining are based on a mathematical model relating control variables to process behavior. Any process model limitations will be reflected in constraints imposed on the entire machine tool system. In this paper process models are viewed as mappings from the control variable space to the process behavior space. The boundaries of useful ranges of these process models are presented in terms of the singularities of the mappings. An example of a typical process model relating cutting force to cutting speed and feed is presented and areas of usefulness of the model defined. The importance of considering qualitative changes in the form of the process model as process parameters change is pointed out.
