| Abstract: |
| In this work, a comprehensive literature review on wear positions and forms of the uncoated tool (including cemented carbide tool, polycrystalline diamond tool and tool of other materials) and the coated tool (including diamond coated tool, diamond-like carbon coated tool and coated tool of other materials) is provided. The wear suppression method (including assisted technology, coating modification and Microstructure) is also summarized. Current studies are mainly based on macro experiments, and there are few at the microscale. Flank face and cutting edge are the main wear positions at the macroscale. Abrasive wear caused by the friction between hard fibers and tools is the main wear form at the microscale. Moreover, the adhesive and oxidative wear occurs at the high cutting temperature and speed level. For milling and drilling, diamond tools (polycrystalline diamond and diamond coating) exhibit the best wear resistance, especially suitable for continuous cutting operations, which becomes the first choice for the high machining quality and productivity of CFRP. However, the main threat of these tools is the fatigue wear (such as coating cracks, peeling and chipping) and abrasive wear due to the high-frequency ploughing action of the high-strength and high-hardness fibers. At the same time, various suppression methods are taken to reduce the tool wear. Under the current wear suppression methods, the average reduction in tool wear is about 50%, while the continuous cutting length is less than 15 m and the flank wear width is about 400 μm at this time. The relevant studies have shown that when the flank wear width is more than 300 μm, the long burrs will occur on the surface of workpiece, which seriously affects the machining quality. Thus, it is still difficult to meet the high quality and efficiency machining of large CFRP structural parts at present. Meanwhile, it can be seen that based on macro and micro experiments, the study of tool wear mechanism and wear suppression method can not meet the requirement for improving the performance of tools. In addition, the experimental cost is high and the wear mechanism observed in experiments is limited. In future, a further study on the wear mechanism and suppression method of the diamond tool from multiscale and multi-method is an urgent requirement for high quality and efficiency machining of CFRP. The work aims to obtain a comprehensive view on the tool wear in cutting of CFRP and make a call for further study of the wear of diamond tools at the multiscale considering microscale and nanoscale mechanism to provide theories and data for wear suppression methods. |
