This paper examines the phonetic properties of the degree adverb “hen” in Yuanjiang dialect (YJD hereafter) with empirical data from local people. Three sets of parameters, i.e. fundamental frequency (F0), duration and tone value (T-value), were analyzed. The degree adverb “hen” in YJD can be used as not only an adverbial but also a complement, and the sound of “hen” varies with syntactic functions and semantics. The results show that “hen” as an adverbial can be read as both “[xei45]” which means “very” and “[xei21]” which implies nearly no practical meaning, and that “hen” being a complement is uttered as “[xei41]”, indicating the meaning of “very” but carrying higher degree and stronger intonation than “[xei45]”. According to phonetic experiments, the sound change of “hen” in YJD lies in the change of tone value without transforming the initial consonant and vowel. Such phonetic phenomenon of ‘‘hen” in YJD is neither literal and colloquial readings nor tone sandhi, but a polyphonic phenomenon caused by internal inflexion.

A forward and automatic method for in-process model generation is proposed and integrated with three-dimensional computer aided process planning (CAPP) system. The method based on feature cutter volume of manufacturing drives the in-process model to evolve from blank to part, which is coincident with the manufacturing process and ideology of process design. At the same time, technology of What-if Alternative Value Engineering (WAVE) is implanted in the generation to establish the relationship of in-process models, which supports function of the automatic update for models. The paper introduces a theory of the solution to demonstrate the connection between manufacture feature and feature cutter volume, and detailedly presents the technological process in applying the WAVE technology. Examples are completed in a commercial CAPP system to illustrate the feasibility of this approach.
