The major needs in machining are high material removal rate, good work surface finish and low tool wear. These objectives can be achieved by reducing tool wear using proper cutting fluid during machining.The effect of some cutting fluids namely: Mentholated spirit, paraffin, and soluble oil on the flank wear of High-speed steel and carbide tipped tools by orthogonal cutting has been studied. Ce...

NiTi alloy wires are widely used in many applications for examples, orthodontic arch wires, mini screw implant, sensors, etc. Usually, wire drawing process is chosen to produce arch wires because of its high productivity as well as superior surface quality of the drawn wire surface. In the case of NITI arch wire, the cold work occurred during wire drawing operation also plays important role to ...

Powder-actuated (also referred to as low velocity or powder-driven) fasteners are commonly used to attach cold-formed steel framing members, usually a track, to a concrete or structural steel support. Although commonly used, their behavior is less well understood than other fasteners such as screws, bolts and welds. The AISI Cold-Formed Steel Design Manual does not explicitly address powder act...

Compared to hot-rolled steel structures, cold-formed steel structures are susceptible to extreme winds because of the light weight of the building and its components. Many modern cold-formed steel structures have sustained significant structural damage ranging from loss of cladding to complete collapse in recent cyclones. This article first provides some real damage cases for light steel struct...

Laser powder bed fusion (LPBF) facilitates economic advantages by enhancing cutting speeds of tools through the implementation complex internal cooling channels that could not be fabricated otherwise. However, tool steels are prone to cracking during cyclic remelting process with extremely fast rates due their high carbon and alloying element contents related stresses. In this work, a correlati...
