“…When CFRPs are processed by laser with short wave length, ablation occurs around the laser spot, which results in cutting of CFRPs [10,11]. While, generation of heat by laser is dominant if the wave length is long, i.e., 1 lm, and mechanism of laser cutting might be similar to thermal processing [10]. The factors affecting on the HAZ are studied a lot in terms of processing.…”

“…Both CF and PR are successfully thermally processed individually, with a CW operated single mode fiber laser, and cutting of CFRP is also possible. [7][8][9][10][11] However, it is not easy to establish excellent cutting quality due to the large difference in melting temperature between two materials. Laser power optimized for CF cutting is too high for PR and generates material damage or burnt so called heat affected zone (HAZ).…”

The power level of Yb doped fiber lasers which operate in continuous wave mode has been increasing in recent years and various kinds of applications using high power single-mode fiber lasers that oscillate in 1microns wavelength range were reported. Single-mode fiber laser that has excellent beam quality of less than 1.1 M 2 value with kW class average power can be focused to tens of microns diameters and its optical power density at the focus point is more than 1x10 8 W/cm 2 . In this power density range, the interaction between 1microns laser light and matter, not only metal materials but non-metal materials, is completely different from that of lower level. The power density initiates laser processing of copper that has relatively high reflectivity at this wavelength range among metals and alumina base plate with over 90% reflectivity. Other interesting material which can be processed by this energy level is carbon fiber reinforced plastics (CFRP). On the other hand, for industrial application and further processing investigation, modulation speed is one of the most important factors because that relates to processing speed and precise control of laser energy input to a material. In this paper, we report on the power dependence of some material processing of copper wafer welding, alumina base plate scribing, and CFRP cutting using single-mode fiber laser which is capable of over 1kW peak power operation and has rapid switching time below 5 micro seconds.

“…Therefore, non-conventional machining processes can be an alternative in order to improve the final performance of the process and minimize its environmental impact. Processes such as abrasive water jet machining or laser machining are alternatives that are currently being widely studied [ 14 , 15 , 16 ]. Nevertheless, defects associated with both processes hinder the accuracy of the drilling process of composite materials [ 17 , 18 ].…”

The novelty of EDM machining as a drilling operation for composite materials means that there is no consensus on the influence of the parameters that optimise the final quality. For these reasons, a characterisation of the EDM drilling process of a unidirectional composite material has been developed. The influence of several cutting parameters has been related to the quality of the final hole obtained. Thus, macrogeometric aspects in terms of conicity and final diameter and microgeometric aspects in terms of surface quality have been evaluated. In addition, the final state of the material and the wear of the electrode have been evaluated by visual inspection, allowing the range of cutting parameters that offer the best performance to be established. Finally, a series of contour diagrams based on predictive models have been obtained to establish a direct relationship between input and output variables.
