FORECASTING MODEL OF MANUFACTURING TIME AT THE EARLY DESIGN STAGE OF PRODUCT AND PROCESS

Abstract

This paper considers the developed forecasting model of a manufacturing time at the early product and process design stage. Developed model forecasts the manufacturing time of machining operations by removed material volume and achieved part’s quantitative-qualitative characteristics. Presented methodology of manufacturing time forecasting on products and their design features classification is based. The design features into two separate class level – rotational and prismatic geometrical form are classified. Consideration on the virtual environment is made; the mathematical formalization of forecasting manufacturing time and repartition of design features in mechanical parts and products applying statistical analyses methods are defined. The proposals how would be possible to classify the design features of products’ and how to define their influence to the manufacturing time by the removed material volume of separate design features.
