Stainless-steel has become a widely preferred material type in the marine, aerospace, sanitary, industrial equipment, and construction industries due to its superior corrosion resistance, high mechanic properties, strength, formability, thermal electrical conductivity. In this study, multi-objective optimization method based on grey relational analysis was employed optimize fiber laser-cutting ...

The laser micro-cutting process is the most widely commonly applied machining which can be to practically all metallic and non-metallic materials. While this had challenges in cutting quality criteria such as geometrical precision, surface numerous others. This article investigates of PEEK composite material using nano-fiber laser, due their significant importunity efficiency various manufactur...

A series of sawing experiments on granite was carried out to explore the cutting performance a diamond frame saw with horizontal reciprocating mode. model average thickness chip established and characteristics forces were analyzed. The wear mechanism segments revealed by analyzing width kerf morphology segments. results demonstrated that resistance increased feed speed. changed abruptly at reve...

Laser straight cutting of zirconia is carried out. Temperature and stress fields developed in the cutting sections are predicted using the finite element code. The morphological changes in the cutting section are examined after incorporating the optical and scanning electron microscopes. The prediction of surface temperature is compared with its counterpart obtained from the thermocouple data. ...

Among functional materials, quasiequiatomic NiTi alloys are one of the most promising and diffused for some sectors, from biomedical to aerospace ones. Their peculiar performance, namely, shape memory effect pseudoelasticity, is induced via a thermomechanical treatment called setting or with heat annealing. This carried out in cold-worked conditions. The present work studies material conditions...

Laser beam cutting (LBC) is a most predominantly used non-traditional cutting process to cut desired shapes out of sheet metals, plates, sections and boxes with greater accuracy at least time. The criticality in this process is its complexity in cutting non ferrous materials due to their lesser absorption rate of the laser beam. Continuous wave CO2 laser and pulsed Nd:YAG laser are the most com...

Cutting or welding heavy metal requires higher laser output power than virtually any other type of materials processing application. In the oil industry, an important heavy metal cutting application is creating the slotted liners used to separate oil from well sediments such as sand and gravel. Traditionally, this was done with diffusion-cooled CO2 slab lasers, but now, kilowatt-class fiber las...
