Abstract
Tailored behaviour of scrap titanium based composites can be done reasonably by laser cutting at the optimum process parameter ranges. Laser cutting is frequently used for manufacturing of composites as an advance machining process. It is suitable for geometrically complex profile cutting in the metals used in manufacturing engineering. In the present work, laser cutting process of scrap titanium matrix composites obtained from scrap (Ti6242 + pure Ti) chips reinforced with aluminium, tin, zirconium, molybdenum were carried out. Actually these materials are being widely used in the aerospace such as aircraft structure. For this reason, it was interesting to develop a new composite from scrap (Ti6242 + Pure Ti) chips reinforced with certain elements and to examine its tailored beahviour of these composites for using in manufacturing engineering. Due to thermal effects of laser cutting process, it should be optimized main operating parameters such as laser power, and cutting speed, gas pressure, etc. on the cutting surface. The evolution of the microhardness underneath the cutting surface due to laser power was examined. The composite used in this study was produced through combined method of powder metallurgical (P/M) and thixoforming (Semi solid). Microstructure of cutting edge and cutting surfaces are investigated in detail by scanning electron microscopy (SEM). Cutting surfaces have been analyzed with 3D optical surface roughness-meter (3D–SurfaScan). Roughness evaluations were taken as optimization criteria as a function of the cutting surface and cutting parameters (power, cutting speed, gas pressure etc.) that have been carried out by Taguchi method. A simple and useful tool was proposed for using in real manufacturing environment.
