Manufacturability factor analysis of product design fulfillment
In the paper there is presented a type and characteristic classification of parts based on the variety of product design fulfillment. The analysis of manufacturability coefficients is carried out to which belong coefficients of standardization, unification, repeatability and typification. Their tie with the labour-intensiveness of design-technological pre-production and labour-intensiveness of part machining is defined. There are shown drawbacks of the coefficients considered, for instances, in coefficients of standardization and unification one does not take into account different degrees of influence upon labour-intensiveness of constituents of these coefficients, besides, a repeated account of standard parts takes place. In the coefficients of typification and repeatability both variety of parts and their number in one group of items or one standard representative are not taken into account.
