Investigation for Manufacturing Culture-Related Specifications of Asian-Oriented Machine Tools

本论文是对一种文化、地域协调机床的调查研究和原型设计，有大量的案例将其转化为产品，学术界对这一问题的研究非常活跃。在本研究中，特别是针对面向亚洲的机床，我们明确了在实际产品中观察到的与制造文化相关的设计规范，分析了今后该机床应赋予的与文化和地域相关的设计属性，并对下一代机床的基本部件主轴系统和工作台系统进行了原型设计。首先，通过对亚洲国家与文化和地域相关的设计属性需求的访谈调查，发现了以下广泛的设计属性：(1)社会属性，如对文化的细致考虑；(2)顾客喜好属性，如坚持使用名牌零部件和部件的机床；(3)先进技术属性，如考虑到机床之间差异的使用技术。此外，还发现这些设计属性可以用二维平面表示；一个轴代表文化和地区层面的力量程度，另一个轴代表模糊性程度。其次，根据文献调研、访谈和实地调研的结果，对机床产品或样机的分析，强调与文化和地域相关的最低层设计属性的“区域协调机床”出现了迄今为止最令人期待的类型。具体来说，从客户的角度来看，“操作方便”和从制造商的角度来看，“制造方便”是特别要考虑的。最后，为了证明这一概念的可行性，考虑到零件数量的减少，新设计并制造了一个轴承内圈集成主轴系统的原型。对样机的静态特性进行了实验评估，结果表明样机的阻尼能力大于传统主轴系统的阻尼能力。为了实现充分考虑“单向可装配性”的工作台系统，除主轴系统外，还提出并设计了“齿条-小齿轮传动式工作台系统”。少

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 … More 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."
