Move command calling Calling a specific custom program from a block containing a move command,
after the move command has been executed.
Multi–edit function Displaying two programs side–by–side so that they can be edited simulta-
Multi–piece machining function Using simplified commands to punch out two or more products of the same
shape from a workpiece.
Multibuffer Preventing interpolation from being stopped between blocks by buffering mul-
Multiple M commands in a single block Enabling the issue of more than one M code in a single block.
Multiple repetitive cycle Canned cycle that is repeated until a program–specified target figure is
attained. By means of this method, the specification of only a final figure, for
example, enables the automatic determination of intermediate tool paths.
Multiple subscreens Displaying information about the current position and a program being
executed on a subscreen (window placed on the main screen).
Multiple tool control Automatically indexing tools in a multiple–tool unit, which consists of two or
more different tools in a single tool holder.
NC statement Non–macro statement block that directly controls the CNC.
Nibbling Punching performed by running the press continuously and repetitively.
Nonlinear interpolation type positioning Positioning individual axes independently.
Normal direction control Controlling a rotary axis so that the tool is oriented in a direction normal to that
of its forward motion.
Normal operation Operation in which the movements of the master and slave axes are specified
using separate axis addresses. This is equivalent to normal CNC operation
and is used to machine workpieces on different tables independently.
Number of registerable programs Number of programs that can be saved to CNC memory.
Offset Deviation from a true tool path or coordinate system origin to compensate for
tool size. Synonymous with “compensation”.
Offset memory CNC memory used for storing tool offset values, workpiece origin offset val-
ues, and external workpiece origin offset values.
Offset mode CNC state in which tool path offset is allowed.
Offset plane Plane in which tool path offset is active.
Offset space Space in which tool path offset is allowed.
Offset vector Vector whose direction and size are the same as those of a specified tool
offset. As the tool advances, the vector direction is rewritten for individual
blocks according to calculations within the CNC so that it is always held nor-
mal to the tool path.
One–digit F code feed Cutting feed in which the tool is fed at the feedrate set in the CNC, and which
corresponds to the digit (from 1 to 9) immediately after the F address.
One–shot G code G code that remains valid only within the block in which it is listed ( such as
Operating monitor display Display of the servo axis load meter, spindle load meter, and speed meter.
