This deals with an investigation research and prototype design on a culture- and region-harmonized machine tool, which has a large number of cases making it into a product, and academic researches regarding this issue has become so active. In this research, especially, concentrating on an Asian-oriented machine tool, we have made clear manufacturing culture-related design specifications observed in actual products, have analyzed culture- and region-related design attributes which should be endowed with such a machine tool hereafter, and also have conducted prototype desings of a spindle system and table system, which are basic components of a machine tool in the next generation.
First, an interview investigation on culture- and region-related design attributes demanded in Asian countries showed that a wide range of design attributes are revealed as follows : (1) social-related attributes, e.g., careful consideration on culture, (2) customers' penchant-related attributes, e.g., persisten
ce to a machine tool with famous brands of parts and units, (3) advanced technology-related attributes, e.g. utilization technology taking into consideration differences between machine tools. Moreover, it has been also found that these design attributes can be expressed in a two-dimensional plane ; one axis represents a degree of strength in cultural and regional level, and the other represents a degree of ambiguity.
Next, according to the results in literature survey, interview and on-the-spot investigation, analysis of products or prototypes of machine tools, "a region-harmonized machine tool" which puts much stress on the lowest layer of culture- and region-related design attributes has appeared the most expected type so far. Concretely speaking, "ease of operation" from a customer's viewpoint and "ease of manufacturing" from a maker's viewpoint are especially taken into consideration.
Last of all, to demonstrate the availability of the concept, an inner ring of bearing integrated spindle system which takes into account the reduction of number of parts, has been newly designed and manufactured as a prototype. An experimental evaluation on a static characteristics of the prototype has displayed that a damping capacity of the prototype is larger than that of conventional spindle system. In addition to the spindle system, "a rack and pinion drive type table system" has been newly proposed and designed to realize a table system with full consideration to "one-directional assemblability."
