Sawing is the process of cutting a workpiece with power band saws, hacksaws, and circular saws. This article discusses the process capabilities and limitations of band sawing. It provides information on band sawing machines, their fixtures and attachments, band construction and materials, blade design, and cutting fluids associated with the band sawing process. The article also discusses the variables considered in band saw machining. In addition, it presents examples representing the comparison of contour band sawing with milling and shaping in various applications. The article concludes with a discussion on the safety precautions to be followed during band sawing and on friction band sawing, circular sawing, and hacksawing.

This article begins with a discussion on machinability ratings of copper and copper alloys and then describes the factors influencing the machinability ratings. It explains the effect of alloying elements, cold working, and cutting fluid on the machinability of copper and copper alloys. In addition, the article provides a comprehensive discussion on various machining techniques that are employed for machining of copper and copper alloys: turning, planing, drilling, reaming, tapping and threading, multiple operation machining, milling, slitting and circular sawing, power band sawing and power hacksawing, grinding, and honing.

Flash welding (FW) is a resistance welding process in which a butt joint weld is produced by a flashing action and by the application of pressure. Flash welding is used to join metallic parts that have similar cross sections in terms of size and shape. This article discusses flash-welding applications, including chain links, transmission bands, automotive flywheel ring gears, aircraft landing gear, band-saw blades, and crankshaft counter weights. It describes the components of a typical flash-welding machine. The article provides information on the electrical controls of flash-welding equipment. These include programmable controllers, welding current controllers, and either motor or servo-valve controllers.

This article focuses on the mechanical and nonmechanical cutting methods used in metal fabrication industries. The most prevalent equipment used for mechanical cutting includes shears, iron workers, nibblers, and band saws. Nonmechanical methods of cutting include gas cutting, electric arc cutting, and laser cutting. The article concludes with information on the advantages of abrasive waterjet cutting, which is an alternative to laser cutting, gas cutting, and plasma cutting.

Mechanical cutting methods are widely used by the metal fabrication industry. This article introduces the welding fabricator to some of the mechanical equipment used to shape or prepare metals for welding. The most prevalent equipment used for mechanical cutting includes shears, iron workers, nibblers, and band saws. The article provides details on each of these.
