A machining scenario is a description of a machining process in which the changes of machining states are described in terms of both geometrical and physical characteristics of machining processes such as geometry of tool-workpiece contact face, cutting force, and machining error. A machining scenario can be automatically generated by a model based cutting simulation. It provides useful information for pre-process optimization of cutting conditions. on-line adaptive control, and monitoring and diagnosis of abnormal occurrences. This paper describes the data structure of the machining scenario and how it can be utilized for the generation of efficient and reliable machining data and realizing intelligent machining operations. The results of experiments by a prototype system are also described to verify its effectiveness.
