to cut straight lines at any angle; to cut arcs; with the addition of a compound table on top of the rotary table, the user can move the center of rotation to anywhere on the part being cut. This enables an arc to be cut at any place on the part. to cut circular pieces; Additionally, if converted to stepper motor operation, with a CNC milling ...
Indexing head. Indexing head and tailstock set up on a milling machine's table. An indexing head, also known as a dividing head or spiral head, [1] is a specialized tool that allows a workpiece to be circularly indexed; that is, easily and precisely rotated to preset angles or circular divisions. Indexing heads are usually used on the tables of ...
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 ...
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.
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, heavy ...
Milling cutter. Milling cutters are cutting tools typically used in milling machines or machining centres to perform milling operations (and occasionally in other machine tools). They remove material by their movement within the machine (e.g., a ball nose mill) or directly from the cutter's shape (e.g., a form tool such as a hobbing cutter).
A digital readout (DRO) is a numeric display, usually with an integrated keyboard and some means of numeric representation. Its integral computer reads signals generated by linear encoders or (less frequently) rotary encoders installed to track machine axes, using these measures to keep track of and display to a machine operator the workpiece ...
Computer-aided manufacturing. CAD model and CNC machined part. Computer-aided manufacturing (CAM) also known as computer-aided modeling or computer-aided machining[1][2][3] is the use of software to control machine tools in the manufacturing of work pieces. [4][5][6][7][8] This is not the only definition for CAM, but it is the most common. [4]
