Unit of measurement for dimensions in the program: Q113
The value of parameter Q113 specifies whether the highest-level NC
program (for nesting with PGM CALL) is programmed in millimeters
or inches.
Dimensions of the main program Parameter value
Metric system (mm) Q113 = 0
Inch system (inches) Q113 = 1
Tool length: Q114
The current value for the tool length is assigned to Q114.
Coordinates after probing during program run
The parameters Q115 to Q118 contain the coordinates of the spindle
position at the moment of contact during programmed measurement
with the 3-D touch probe.
The length and radius of the probe tip are not compensated in these
coordinates.
