Process modeling for quality in order-handled manufacturing system.

This paper deals with mechanical products process modeling for quality in order-handling manufacturing system. It investigates an influence of the product and process qualitatives-quantitatives indications to the manufacturing quality. The research is based on product design features peculiarities as material, geometrical form, dimensions, tolerances, and roughness of surfaces and so on. The graph theory for transformation of mechanical part drawings' data into digital codes has been applied. The developed model can forecast product manufacturing and quality cost at the early stage of a product design and also it is useful at the new business consideration phase in orderhandling manufacturing systems. Modeling of quality cost can decrease the risk of production errors in high variety and low volume manufacturing system rightly estimating its possibilities and suggesting decision making for creation of a right process structure and fabrication facility and tooling aiming the minimal production and quality costs. The created model is tested and validated in two Lithuanian manufacturing companies and it is able to use in mechanical engineering industry and also for study process in technical universities.
