Still widely used today (versatile, affordable, capable) although carbide and others continue to erode its share of commercial applications in inch (es) IPF inches per flute Also known as chip load or IPT.
For some controls (fanuc) the first LF (EOB) is start of program.
M52 Unload Last tool from spindle lso empty spindle.
Full circles: When the arc start point and the arc end point are identical, the tool cuts a 360 arc (a full circle).G50 Define the maximum spindle speed T Takes an S address integer, which is interpreted as rpm.Whereas older manual CNC programming could only describe particular instances of parts in numeric form, macro programming describes abstractions that can easily apply in a wide variety of instances.HBM horizontal boring mill A type of machine tool that specializes in boring, typically large holes in large workpieces.Not standard on Fanuc controls.Shorter vector usually finishes first (given similar axis art of war games 320x240 speeds).Y Absolute or incremental position of Y axis Z Absolute or incremental position of Z axis The main spindle's axis of rotation often determines which axis of a machine tool is labeled.Thus, an operator tending multiple machines is told by a machine, essentially, "Pause what you're doing over there, and come attend to something over here." It is common practice to bring the tool in rapidly to a "safe" point that is close to the partin.Position register can still be useful for datum shift programming.External links edit CNC G-Code and M-Code Programming Tutorial for G-code Kramer,.See speeds and feeds.N Line (block) number in program; System parameter number to change using G10 Line (block) numbers: Optional, so often omitted.CSS constant surface speed See G96 for explanation.Assumed to be 1 unless programmed with another integer.
G44 Tool height offset compensation positive M Takes an address, usually H, to call the tool length offset register value.
Turning: Often needs no D or H address on lathes, because whatever tool is active automatically calls its geometry offsets with.
