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

这涉及到一种文化和地域协调的机床的调查研究和原型设计，它有大量的案例成为产品，关于这个问题的学术研究变得如此活跃。本研究特别针对面向亚洲的机床，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，分析了今后应赋予这种机床的文化和地域相关的设计属性，并对下一代机床的基本组成部分--主轴系统和工作台系统进行了原型设计。首先，对亚洲国家对文化和地域相关设计属性的需求进行了访谈调查，揭示了以下广泛的设计属性：(1)社会相关属性，如认真考虑文化，(2)客户喜好相关属性，如Persisten…(3)与先进技术相关的属性，例如考虑到机床之间的差异的利用技术。此外，还发现这些设计属性可以在一个二维平面上表达，一个轴代表着文化和地域层面的力量程度，另一个轴代表着一定程度的模糊。其次，根据文献调查、访谈和实地考察的结果，对机床产品或原型的分析表明，目前最受期待的类型是强调与文化和地域相关的设计属性的最低层的区域协调机床。具体地说，特别考虑了从用户角度看的“操作方便”和从制造商角度看的“制造方便”。最后，为了证明这一概念的可行性，设计并制造了一种考虑零件数量减少的轴承集成主轴系统内圈。对样机静态特性的实验评价表明，样机的减振能力大于常规主轴系统。在主轴系统的基础上，新提出并设计了齿条小齿轮传动型工作台系统，实现了充分考虑“单向可装配性”的工作台系统。较少

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."
