In metalworking and woodworking, an automatic lathe is a lathe with an automatically controlled cutting process. Automatic lathes were first developed in the 1870s and were mechanically controlled. From the advent of NC and CNC in the 1950s, the term automatic lathe has generally been used for only mechanically controlled lathes, although some ...
Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
Henry Maudslay 's early screw-cutting lathes of circa 1797 and 1800. A screw-cutting lathe is a machine (specifically, a lathe) capable of cutting very accurate screw threads via single-point screw-cutting, which is the process of guiding the linear motion of the tool bit in a precisely known ratio to the rotating motion of the workpiece.
A CNC metal lathe with the door open. In machining, numerical control, also called computer numerical control (CNC), [1] is the automated control of tools by means of a computer. [2] It is used to operate tools such as drills, lathes, mills, grinders, routers and 3D printers. CNC transforms a piece of material (metal, plastic, wood, ceramic ...
Metal lathe. Center lathe with digital read out and chuck guard. Size is 460 mm diameter x 1000 mm between centers. In machining, a metal lathe or metalworking lathe is a large class of lathes designed for precisely machining relatively hard materials.
Edgar T. Westbury was perhaps best known as a major contributor to the English recreational magazine Model Engineer. He contributed under his own name, and also under the pseudonyms 'Artificer', 'Ned', 'Kinemette' and Exactus. [1][2] Beginning in 1925 until his death in 1970, he made over 1474 authored contributions to Model Engineer under his ...
Shaper. In machining, a shaper is a type of machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to machine a linear toolpath. Its cut is analogous to that of a lathe, except that it is (archetypally) linear instead of helical. A wood shaper is a functionally different woodworking tool, typically ...
Cutting tool (machining) In the context of machining, a cutting tool or cutter is typically a hardened metal tool that is used to cut, shape, and remove material from a workpiece by means of machining tools as well as abrasive tools by way of shear deformation. The majority of these tools are designed exclusively for metals.
