Machined powertrain components are a subset of machined parts that introduce unique and difficult problems to product design, process planning and manufacturing system design for the automotive industry. They are complex, high value-added components that must be produced at large volumes to stringent quality standards. Accordingly product development cycles are typically long. Integrated computer-aided approaches are thus desirable for reducing this time and helping manufacturing engineers design the best process and specify the optimal manufacturing system configuration. This paper presents a framework for integrating Computer-Aided Design (CAD), Computer-Aided Process Planning (CAPP) and Computer-Aided Manufacturing Systems Engineering (CAE-MS) for producing machined powertrain components. It describes the key components of this framework and in some cases details of the methods and technologies adopted for their realization. This solution is based upon a feature-centric philosophy. This stands in contrast to the product-variant approach that has been common practice in this industry.

Process planning and system design for automotive powertrain machining represent a large investment in engineering upon which decisions are made for equipment acquisitions that typically falls in the range of hundreds of millions of dollars. The use of Computer-Aided Process Planning (CAPP) and system design (CASD) applications in the early stages of a new engine program can greatly increase the reliability and quality of the solutions upon which these decisions are made. They can also reduce the engineering time and the time to evaluate proposals from system integrators. This leads to shorter product launch windows giving manufacturers a competitive edge. This paper reports upon a case study conducted to evaluate the state of the art in of CAPP and CASD technology based on a typical configuration of commercial and evolving software applications. The results show maturity of the technology in most of the core technologies. Challenges exist in integrating these solutions into a manufacturer’s working environment.

ISO 14649, known as STEP-NC, is new model of data transfer between CAD/CAM systems and CNC machines. In this paper, the modeling based on machining feature is proposed. The machining feature comes from the manufacturing process considering the restriction of machining technology and machining resource. Then the framework for computer aided process planning is presented, where the algorithms of operation planning is studied. The practical example has been provided and results indicate that machining feature based model can integrate with CAPP and STEP-NC seamlessly.
