Process modeling for quality in order-handled manufacturing system

Abstract

This paper deals with mechanical products processmodeling for quality in order-handling manufacturingsystem. It investigates an influence of the product andprocess qualitatives-quantitatives indications to the manufacturingquality. The research is based on product designfeatures peculiarities as material, geometrical form, dimensions,tolerances, and roughness of surfaces and so on. Thegraph theory for transformation of mechanical part drawings’data into digital codes has been applied. The developedmodel can forecast product manufacturing and qualitycost at the early stage of a product design and also it isuseful at the new business consideration phase in orderhandlingmanufacturing systems. Modeling of quality costcan decrease the risk of production errors in high varietyand low volume manufacturing system rightly estimatingits possibilities and suggesting decision making for creationof a right process structure and fabrication facility andtooling aiming the minimal production and quality costs.The created model is tested and validated in two Lithuanianmanufacturing companies and it is able to use in mechanicalengineering industry and also for study process intechnical universities.
