Coolant on/off: Q111
Overlap factor: Q112
The overlap factor for pocket milling (MP7430) is assigned to Q112.
Unit of measurement for dimensions in the
program: Q113
The value of parameter Q113 specifies whether the highest-level NC
program (for nesting with %...) is programmed in millimeters or
inches.
Tool length: Q114
The current value for the tool length is assigned to Q114.
Coordinates after probing during program run
The parameters Q115 to Q119 contain the coordinates of the spindle
position at the moment of contact during programmed measurement
with the 3-D touch probe. The coordinates are referenced to the
datum that is currently active in the Manual operating mode.
The length and radius of the probe tip are not compensated in these
coordinates.
