Canned cycles are so called because they allow a concise way to program a machine to produce a feature of a part. [2] A canned cycle is also known as a fixed cycle . A canned cycle is usually permanently stored as a pre-program in the machine's controller and cannot be altered by the user.
The part program is a sequence of instruction that describe the work that is to be done to a part. Typically these instructions are generated in Computer-aided manufacturing software and are then fed into the computer numerical control (CNC) software on the machines, such as drills, lathes, mills, grinders, routers, that are performing work on the part.
Developed at MIT, BCL was developed to control CNC machines in terms of straight lines and arcs. [9] Some CNC machines use "conversational" programming, which is a wizard-like programming mode that either hides G-code or completely bypasses the use of G-code. Some popular examples are Okuma's Advanced One Touch (AOT), Southwestern Industries ...
A CNC machine that operates on wood CNC machines typically use some kind of coolant, typically a water-miscible oil, to keep the tool and parts from getting hot. 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]
STEP-NC interface on a CNC, showing product shape and color-coded tolerance state. STEP-NC is a machine tool control language that extends the ISO 10303 STEP standards with the machining model in ISO 14649, [1] adding geometric dimension and tolerance data for inspection, and the STEP PDM model for integration into the wider enterprise.
Hard turning is a type of turning done on materials with a Rockwell C hardness greater than 45. It is typically performed after the workpiece is heat treated. [3] The process is intended to replace or limit traditional grinding operations. Hard turning, when applied for purely stock removal purposes, competes favorably with rough grinding.
A typical example involves an XY table that positions each hole center, where the spindle (Z-axis) then completes a fixed cycle for drilling by plunging and retracting axially. The code for 2.5D machining is significantly less complex than 3D contour machining, and the software and hardware requirements are (traditionally) less expensive.
Facing on a lathe (perpendicular to the axis of rotation), which is commonly used in turning and boring operations. Other operations remove material in ways similar to facing, for example, planing, shaping, and grinding, but these processes are not labeled by the term "facing."
