摘要

碳纤维增强聚合物（CFRP）因其优异的性能而被广泛应用于重要的基础部件中。本文介绍了不同的方法，包括干式加工的传统 PCD 刀具（CPD）、二氧化碳低温冷却的传统 PCD 刀具（CPC）和二氧化碳低温冷却的纹理 PCD 刀具（TPC），以研究它们对制孔性能的影响。结果表明，使用 CPC 时，不同主轴转速下获得的平均入口直径和相对误差分别约为 4001 至 4005.4 μm 和 0.025% 至 0.65%。采用 CPC 方法可以更好地提高入口孔的尺寸精度和表面边缘质量。研究发现，与干式加工相比，低温冷却法在改善刀具抗粘附性方面效果显著。此外，研究结果表明，低温冷却会导致孔壁出现明显的纤维断裂和许多凹坑，而 CPD 方法有助于改善孔壁质量。

Investigation on effect of cryogenic cooling on the hole-making of CFRP with conventional PCD tool and textured PCD tool

Carbon fiber reinforced polymer (CFRP) has obtained the widespread use in significant basic parts owing to its excellent properties. Different methods including the conventional PCD tool using dry machining (CPD), the conventional PCD tool with CO2 cryogenic cooling (CPC), and the textured PCD tool with CO2 cryogenic cooling (TPC), were introduced to investigated their effects on the holes-making performance. Results demonstrated that the obtained average entrance diameter and relative error of different spindle speeds using the CPC were about 4001 to 4005.4 μm and 0.025% to 0.65%, respectively. Dimensional accuracy and surface edge quality of entrance hole can be better improved by the CPC method. It was found that the cryogenic cooling method showed the remarkable effect in improving the anti-adhesion of tools than compared to the dry machining. Additionally, results indicated that the cryogenic cooling resulted in the significant fiber fractures and many pits inside the hole wall and the CPD method can help to improve the inner hole wall quality.

期刊介绍： Manufacturing industries throughout the world are changing very rapidly. New concepts and methods are being developed and exploited to enable efficient and effective manufacturing. Existing manufacturing processes are being improved to meet the requirements of lean and agile manufacturing. The aim of the Journal of Engineering Manufacture is to provide a focus for these developments in engineering manufacture by publishing original papers and review papers covering technological and scientific research, developments and management implementation in manufacturing. This journal is also peer reviewed. Contributions are welcomed in the broad areas of manufacturing processes, manufacturing technology and factory automation, digital manufacturing, design and manufacturing systems including management relevant to engineering manufacture. Of particular interest at the present time would be papers concerned with digital manufacturing, metrology enabled manufacturing, smart factory, additive manufacturing and composites as well as specialist manufacturing fields like nanotechnology, sustainable & clean manufacturing and bio-manufacturing. Articles may be Research Papers, Reviews, Technical Notes, or Short Communications.
