Semi-automated process planning and cost estimation of turned components based on CATIA V5 Machining

In an environment of increasing globalization, companies are facing greater competition. This pushes them to constantly improve their competitiveness in order to maintain their market position.

To be more competitive in the market, many companies are trying to speed up the quotation process and quote more attractive prices. Therefore, they have identified a need for support in the quotation process in order to reduce the quotation lead-time and ensure a higher level of accuracy in the cost estimations. The Quotation Calculator, an application program, has been developed as part of the degree thesis…
