Abstract [en]

For many products, the adaption to customer specifications is essential and requires flexible product design and manufacture while maintaining competitive pricing. A large category of design work in industry has the character of the redesigning of an existing product concept in terms of dimensional changes, topology variations and the configuration of components. In order to evaluate design proposals, costs, controlled by the product design, selected materials and manufacturing processes, need to be estimated. Cost estimates are normally based on the manufacturing process plans. They, in turn, can only be formed when production preparation is finalised. The widespread industrial use of solid modelling opens up new possibilities for automating this process. The purpose of this work is to demonstrate and test a method of extracting product information from a CAD model in order to allow process planning and cost calculation to be carried out automatically for a given class of products. With such a system, cost estimates can be made available to the designer the instant a design proposal has been presented. This allows design iterations to be carried out, in order to govern the design work towards solutions with an optimal balance between product and production properties.
