Nowadays high speed machining (HSM) machine tool combines productivity and
part quality. So mould and die maker invested in HSM. Die and mould features
are more and more complex shaped. Thus, it is difficult to choose the best
machining strategy according to part shape. Geometrical analysis of machining
features is not sufficient to make an optimal choice. Some research show that
security, technical, functional and economical constrains must be taken into
account to elaborate a machining strategy.
This paper will provide a method to decompose forging dies for machining
planning in the case of high speed machining finishing operations. This method
lies on a machining feature approach model presented in the following paper.
The two main decomposition phases, called Basic Machining Features Extraction
and Process Planning Generation, are presented. These two decomposition phases
integrates machining resources models and expert machining knowledge to provide
an outstanding process planning.
Today's High-Speed Machining (HSM) machine tool combines productivity and
part quality. The difficulty inherent in HSM operations lies in understanding
the impact of machine tool behaviour on machining time and part quality.
Analysis of some of the relevant ISO standards (230-1998, 10791-1998) and a
complementary protocol for better understanding HSM technology are presented in
the first part of this paper. These ISO standards are devoted to the procedures
implemented in order to study the behavior of machine tool.
