摘要
The fast industrial development causes progressive rising demands for energy and materials, which are in opposition to a shortage of basic materials. The consequence consists in rising costs for energy as well as materials, which leads to challenges in competitive capability especially for small and medium-sized enterprises. The technological comparison of variants within the process planning as innovative approach for the reduction of a company's resource demand as well as the design of the technological planning algorithms has to be extended with appropriate energetical evaluation methods. Modeling, screening and application of manufacturing variants are specified within the technological planning and might contribute to realize a required and necessary reduction of resources. The production of high-precision components for the aviation industry causes machining effort up to 97% of raw material. The resultant considerable resource demands ought to be reduced by the selection of the manufacturing variant and/ or a new consideration of used raw materials. Based on those experiences, a systematic approach for the sustainable process planning is evolved.
