High power fiber laser sources, with a radiation wavelength equal to about 1 µm, offer a great potential in improving the productivity and quality of thin aluminum, magnesium and titanium alloys sheets cutting. This is due to their benefits that are of special interest for this application: power efficiency, beam guidance and beam quality. In this work, an overview regarding the phenomena that for different reasons affect the laser cutting of these materials was given. These phenomena include the formation of a heat affected zone, the chemical contamination, the change of corrosion resistance, the thermal reactivity, the effects of thermal conductivity, reflectivity and viscosity of molten material. The influence of processing parameters on 1 mm thick Al 1050, AZ31 and Ti6Al4V lightweight alloys were experimentally investigated and cutting performances in terms of cut quality, maximum processing speeds and severance energies were evaluated. The advantages of using 1 µm laser wavelength for thin sheets lightweight alloys cutting due to the good cut quality, high productivity and the easily delivery of the beam through the optical fiber, were demonstrated. Results showed that fiber lasers open up new solutions for cutting lightweight alloys for applications like coil sheet cutting, laser blanking, trimming and cutting-welding combination in tailor welded blanks applications.

“…Argon gas was used as a cutting medium. 1 mm thick sheets were cut, and the altered properties of the cut zone were investigated [102]. Once laser processing was conducted on Ti 6 Al 4 V, torsional tests were conducted on samples of different porosities to test the deformation and mechanical behavior of the samples [34].…”

Abstract:The alloy Ti 6 Al 4 V has evolved as a good biomedical material, by virtue of its bio-compatibility. In order to make implants out of this material, it has to be shaped and processed. Shaping this material by conventional manufacturing methods like machining, welding and brazing presents a huge challenge. This challenge has been met by various approaches like additive manufacturing, surface alloying and heat treatment. Additive manufacturing processes are used for shaping; coatings and surface alloying are used for property improvement; heat treatment is used for improving the machinability. The processing method has an impact on the final properties of the product. This review attempts to trace the development of methods and practices for converting Ti 6 Al 4 V into a useful material for biomedical applications.

“…The kerf widths with nitrogen assisted gas were generally wider. Scintilla et al [6] presented results of Ytterbium fiber laser cutting of Ti6Al4V sheets (1mm thick) performed with Argon as cutting assistance gas. The effect of cutting speed and shear gas pressure on the HAZ thickness, squareness, roughness and dross attachment was investigated.…”

The coronary stent fabrication requires high precision profile cut. Fiber lasers present a solution to accomplish these requirements. This paper presents an experimental study of fiber laser cutting of 316L stainless steel thin sheets. The effect of peak pulse power, pulse frequency and cutting speed on the cutting quality for fixed gas type and gas pressure were investigated. A mathematical model for the dross dimensions was formulated. The dross height and the dross diameter were analyzed and compared with the experimental results. This allows selecting the process parameters to reduce the dimensions of the dross deposited at the bottom of the workpiece.
