Deductive method of conceptual design for Meso lathe based on fuzzy synthetic judgment

On the basis of currently existed concept designing method of mechanical product based on layer analysis of function, a kind of implementation method for fuzzy synthetic judgement was introduced. Fuzzy synthetic judgement has already many applications in conceptual design, what is different form the past is that this method introduces the fuzzy algorithm in the whole course of firstly obtaining the principle solution to finally obtaining an optimum scheme, it is not alike in design to ordinary lathes. Basic thought and organization of algorithm of this method have been described in detail in this paper, and a demonstration was carried out by taking the course of conceptual design of Meso lathe as an example.
