Cutting tool materials must be harder than the material which is to be cut, and the tool must be able to withstand the heat and force generated in the metal-cutting process. Also, the tool must have a specific geometry, with clearance angles designed so that the cutting edge can contact the workpiece without the rest of the tool dragging on the ...
Table saw. A table saw (also known as a sawbench or bench saw in England) is a woodworking tool, consisting of a circular saw blade, mounted on an arbor, that is driven by an electric motor (directly, by belt, by cable, or by gears). The drive mechanism is mounted below a table that provides support for the material, usually wood, being cut ...
Metalworking is the process of shaping and reshaping metals in order to create useful objects, parts, assemblies, and large scale structures. As a term, it covers a wide and diverse range of processes, skills, and tools for producing objects on every scale: from huge ships, buildings, and bridges, down to precise engine parts and delicate ...
A metal lathe is an example of a machine tool. A machine tool is a machine for handling or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformations. Machine tools employ some sort of tool that does the cutting or shaping. All machine tools have some means of constraining the ...
The upper and lower blades are the piece of machinery that actually do the cutting, while the gauging device is used to ensure that the workpiece gets worked where it is supposed to be. Close-up of upper blade, lower blade, backgauge and work-holding device of a Gasparini guillotine shear. The design of press tools is an engineering compromise.
Reciprocating saws have many uses; here, one is shown cutting through hard-to-remove nails in a staircase. A reciprocating saw is a type of handheld, small, machine-powered saw, in which the cutting action is achieved through a push-and-pull ("reciprocating") or back-and-forth motion of the blade. The original trade name, Sawzall, is often used ...
A hand-held circular saw is the most conventional circular saw. This miter saw is a circular saw mounted to swing to crosscut wood at an angle. A table saw. Tractor-driven circular saw. A circular saw or a buzz saw, is a power-saw using a toothed or abrasive disc or blade to cut different materials using a rotary motion spinning around an arbor.
Milling is the process of machining using rotary cutters to remove material [ 1] by advancing a cutter into a workpiece. This may be done by varying directions [ 2] on one or several axes, cutter head speed, and pressure. [ 3] Milling covers a wide variety of different operations and machines, on scales from small individual parts to large ...
