A Knowledge base model for complex forging die machining
Recent evolutions on forging process induce more complex shape on forging die. These evolutions, combined with High Speed Machining (HSM) process of forging die lead to important increase in time for machining preparation. In this context, an original approach for generating machining process based on machining knowledge is proposed in this paper. The core of this approach is to decompose a CAD...
متن کاملDecomposition of forging die for high speed machining
Today's forging die manufacturing process must be adapted to several evolutions in machining process generation: CAD/CAM models, CAM software solutions and High Speed Machining (HSM). In this context, the adequacy between die shape and HSM process is in the core of machining preparation and process planning approaches. This paper deals with an original approach of machining preparation integrat...
متن کاملBuilding a Machining Knowledge Base for Intelligent Machine Tools
Intelligent machines respond to external environments on the basis of decisions that are made by sensing the changes in the environment and analyzing the obtained information. This study focuses on the construction of a knowledge base which enables decision making with that information. Approximately 70% of all errors that occur in machine tools are caused by thermal errors. In order to proacti...
متن کاملDecomposition of forging dies for machining planning
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 ...
متن کاملClose-die Flashless Forging in Automotive Industry
This paper describes the possibilities and conditions of the closed-die flashless forging process using conventional mechanical presses and equipment. The technique of driven gear forging with an internal flash or with special die design has been developed. The quality of forgings is comparable to that achievable on Hatebur presses. Furthermore the problem of how to increase shift production un...
