近年来，具有优异力学性能的碳纤维增强塑料（CFRP）在各个领域的需求量不断增加。特别地，CFRP的用量占最先进飞机的机体结构重量的50%以上。此外，在这种飞机中，经常使用CFRP和钛合金（Ti合金）的组合的叠层材料。因此，需要一种新型的高效端铣技术来同时切削碳纤维复合材料和钛合金。已知为了抑制工具磨损的发生，具有高硬度的金刚石涂层是有用的。另一方面，在加工钛合金的情况下，由于加工热而出现几个问题。因此，在本研究中，我们专注于cBN（立方氮化硼）。为了比较金刚石涂层和cBN，还制备了电镀金刚石颗粒的立铣刀。在这项研究中，作为切削实验，侧铣堆叠材料，这是一个组合的CFRP和Ti-6Al-4V，使用制造的工具进行。然后，通过测量CFRP温度和切屑温度、刀具磨损、表面粗糙度和表面完整性来讨论它们的切削性能。结果，可以预期用制造的电镀cBN端铣刀精确地切割堆叠材料。然而，可以看出，需要改进工具形状或电沉积工艺。
In recent years, the demand for carbon fiber reinforced plastics (CFRP), which have excellent mechanical properties, is increasing in various fields. In particular, the amount of CFRP used accounts for more than 50% of the body structure weight of the state-of-the-art airplanes. Moreover, in such airplanes, stack material, which is a combination of CFRP and titanium alloy (Ti-alloy), is frequently used. Therefore, a novel high-efficiency end-milling technology for cutting CFRP and Ti-alloy simultaneously is required. It is known that for restraining the occurrence of tool wear, diamond coating, which has high hardness, is useful. On the other hand, in the case of machining of Ti-alloy, several problems arise due to the machining heat. Consequently, in this study, we focus on cBN (cubic boron nitride). In order to compare diamond coating and cBN, end-mills, which were electroplated diamond grains, were also fabricated. In this study, as a cutting experiment, side milling of stack material, which is a combination of CFRP and Ti-6Al-4V, was carried out using the fabricated tools. Then, we discuss their cutting performance by measuring the CFRP temperature and chip temperature, tool wear, surface roughness, and surface integrity. As a result, it could be expected to precisely cut the stack material with the fabricated electroplated cBN end-mill. However, it is seen that improvement of the tool shape or the electrodeposition process is required.
