项目摘要

This application study aims to develop the new electrodeposited diamond wire tool which ensures high machining performance and makes a longer life of tool. In order to be able to achieve these purpose, (1) the spiral wire tool which is electrodeposited spiral diamond grains on a piano wire (phi0.2mm), and (2) the twisted wire tool which is electrodeposited diamond grains uniformly on the twisted wire consisted of two piano wires (phi0.1mm) are developed. In addition, these new wire tools are not only produced by way of trial but also examined on both the strength characteristics and the machining performance experimentally. The following points have been noted.1.From the results on the strength characteristics for breaking load of the new wire tools, the spiral wire tool is equal to the conventional wire tool used a phi0.2mm piano wire, and the twisted wire tool tends to decrease to be compared with the conventional wire tool owing to decrease of about 50% in the cross section area of … More the tool. However, this decrease ratio is about 30% because of the improvement of material strength due to decrease of a piano wire diameter.2.From the results on the twisted strength characteristics of the new wire tools, both spiral and twisted wire tools improve approximately 3 times of the conventional wire tool.3.From the results on the machining efficiency by the new wire tools, each of the spiral wire tool and the twisted wire tool shows improvement of aproximately 1.8 and 2 times in maximum of the conventional wire tool. Furthermore, it is clear that the new wire tools have improved the in-outflow effect of the working fluid and the eliminating effect of cutting chips owing to the spiral chip-pocket formed on an each wire tool.4.Twisted wire tool shows a remarkable improvement in the tool life compared with the conventional wire tool.5.From the results on the machining accuracy of edge chipping and wafer roughness by the new wire tools, the spiral wire tool shows a little deterioration compared with the conventional wire tool. However, it is clear that the machining accuracy by the twisted wire tool is presented an equal quantity with the conventional wire tool even though the machining efficiency by the twisted wire tool improver remarkably.

本应用研究旨在开发一种既能保证高加工性能又能延长刀具寿命的新型电沉积金刚石线刀具。为了能够实现这些目的，（1）研制了在一根Φ 0.2mm的钢琴丝上电沉积螺旋状金刚石颗粒的螺旋丝工具，（2）研制了在两根Φ 0.1mm的钢琴丝组成的扭丝上均匀电沉积金刚石颗粒的扭丝工具。此外，这些新的线切割工具不仅通过试制，而且还通过实验对强度特性和加工性能进行了检验。1.从新型钢丝工具的断裂载荷的强度特性的结果来看，螺旋钢丝工具与使用φ 0.2mm钢琴丝的传统钢丝工具相等，而扭线钢丝工具与传统钢丝工具相比，由于扭线钢丝工具的横截面积减小了约50%，因此有减小的趋势。 ...更多信息工具。然而，由于钢琴线直径的减小而提高了材料强度，因此该降低率约为30%。2.从新型线工具的扭转强度特性的结果来看，螺旋线工具和扭转线工具都比传统线工具提高了约3倍。3.从新型线工具的加工效率的结果来看，螺旋线工具和绞合线工具中的每一个都显示出比传统线工具最大大约1.8倍和2倍的改进。此外，由于螺旋形的切屑槽，新型线切割工具改善了工作流体的进出效果和切屑的消除效果。4.与传统线切割工具相比，扭线切割工具在刀具寿命方面有显著的提高。5.从新型线切割工具的边缘切屑和晶片粗糙度的加工精度的结果来看，与传统的金属丝工具相比，螺旋金属丝工具显示出很小的劣化。然而，很明显，即使通过扭线工具的加工效率显著提高，通过扭线工具的加工精度也与传统的线工具表现出相同的量。少
