It has become very important to develop "Asian-oriented machine tools" in accordance with the skill level and culture of manufacturing in Asian countries A concept we have proposed in this research to make a solution to ease of assembly is "one-way assembly." In concrete, we have developed a prototype of a table system based on the concept and evaluated the motion accuracy. Second, we have also proposed a quantitative evaluation method for ease of assembly as an ambiguous factor and applied the method to the assembly processes of the table system developed.(i)The specifications required for the Asian-oriented machine tools have been investigated. According to the investigations, a table system composed of a rack-pinion drive and a linear roller guide way has been developed as a prototype of one-way assembly system.(ii)As a result of investigating the assembly and disassembly processes in detail, one-way assembly has been proven to be available.(iii)When the motion accuracy of the table system has been measured after several assembly and disassembly processes, it has been analyzed that assembly and disassembly processes have small influences on pitching and large influences on yawing of the motion.(iv)An evaluation method of ease of assembly has been proposed using the analysis of the RRV change and the wavelet analysis of RRI obtained from the operator.(v)Applying the evaluation method to the actual assembly processes of the developed table system, an assembly with handling other parts by one hand, screwing in horizontal direction and assembly within a narrow space have been found difficult.(vi)We have concluded that "single-operation assembly" as well as "one-way assembly" should be taken into consideration in machine tool component design and that the combination of rack-pinion drive and linear roller guide way could satisfy both of the concepts.

根据亚洲国家的技能水平和制造文化，我们在这项研究中提出的一个概念是“单程组装”，这已经变得非常重要。在混凝土中，我们基于概念开发了表系统的原型，并评估了运动精度。其次，我们还提出了一种定量评估方法，以简化组装作为模棱两可的因素，并将方法应用于开发的表系统的组装过程。（i）已经研究了面向亚洲的机床所需的规格。根据调查，已开发了一个由齿条杆驱动器和线性辊指南组成的表系统，作为单程组装系统的原型。（ii）由于研究了组装和拆卸过程的结果，单向组装已被证明已被证明是在桌子系统的准确性上进行的。拆卸过程对倾斜的影响和对运动的偏航的影响很小。（iv）使用RRV变化的分析和从操作员获得的RRI的小波分析进行了一种评估方法。 （vi）我们已经得出结论，在机床组件设计中应考虑“单操作组件”以及“单向组件”，并且架子杆驱动器和线性辊指南的组合可以满足这两个概念。
