This study deals with the selection of cutting process using grey fuzzy relation approach. The analysis was performed plasma arc machining, laser beam and abrasive waterjet machining on three different workpiece thicknesses speeds. objective to select best considering several performance characteristics such as time, dimensional accuracy, kerf width, surface roughness. Data normalization, coeff...

Accurate sawing requires attention to proper alignment and maintenance. Alignment is critical to modern sawmills using thin kerf saws. In fact, the improvements in machine design were critical to the development of thin kerf sawing systems. About two-thirds of sawing problems are caused by misalignment, not saw preparation. Good alignment reduces down-time and machinery wear and should be part ...

Abstract Titanium alloy Ti6Al4V is widely used in aerospace, shipbuilding, petrochemical, and other industrial fields. Low-speed wire-cut electrical discharge machining (LS-WEDM) has the advantage of high accuracy. However, there are few research studies on comprehensive effects parameters TC4 (Ti6Al4V) made by LS-WEDM surface. This paper focuses titanium investigates surface roughness, kerf wi...

High power single mode fiber lasers are an excellent tool for micro cutting applications. In order to manage the heat input into the material most micro cutting applications require pulsed operation of the laser. Temporal pulse shaping is a proven and enabling technology for many laser welding applications with flash lamp pumped lasers where typical pulse lengths are in the order of 0.1 to 10 m...

This paper presents an experimental research that proposes to determine the influence of process parameters on CO2 laser cutting 8 mm thick Hardox 400 steel, for which Kerf has a minimum value. The was conducted according complete factorial plan with power, assistant gas pressure and speed as input parameters, width dependable variable. Design Experiment (DOE) consisted 27 references completed ...

-The technologically important case of reactive gas laser cutting is examined. A transient twodimensional (2D) model is developed specifically to investigate the effect of various CNC velocity profiles on the resulting cutting front temperature. Co-ordinated motion systems must ramp up and down to their target speeds, and therefore such accelerations must be considered. In doing so, the dynamic...

Hot-wire cutting is a common material removal process used to shape and sculpt plastic foam materials, such as expanded polystyrene (EPS). Due to the low cost and sculpt-ability of plastic foams they are popular materials for large sized (> 1 m3) prototypes and bespoke visual artefacts. Recent developments in robotic foam sculpting machines have greatly increased the ability of hot-tools to scu...

While dismantling nuclear power plants, the reactor vessel internal is cut underwater using mechanical and thermal cutting. In laser cutting, assist gas must be used to remove melted metal; consequently, a large number of radioactive aerosols can generated. To reduce generation aerosols, pressure should lowered. However, below limit, molten metal not well-removed from surface fails cut. this st...

The investigation was carried out by making use of the design experiments method in order to achieve its objective, which study wear analysis relation a cryogenically treated nozzle that utilized plasma arc machining. Kerf width and surface roughness are two output characteristics key variables deciding quality cut efficiency operation. Both these metrics outputted process. While machining S235...

Lithium-ion batteries are widely used for many applications such as portable electronic devices and Electric Vehicles, because they have lighter weight, higher energy density, higher power density, and a higher energy-to-weight ratio than other types of batteries. Conventional contact-based cutting technology may be inefficient whenever cell design is changed since lithium-ion battery cells are...
