11 Tables, Overviews, Diagrams
Overlap factor: Q112
The overlap factor for pocket milling (MP 7430) is assigned to Q112.
Unit of measurement: Q113
The value of parameter Q113 specifies whether the highest-level NC
program (for nesting with %) is programmed in millimeters or inches.
After NC start, Q113 is set as follows:
Unit of measurement (main program) Parameter value
Millimeters Q113 = 0
Inches Q113 = 1
Current tool length: Q114
The current value of the tool length is assigned to Q114.
Coordinates from probing during program run
Parameters Q115 to Q118 are assigned the coordinates of the spindle
position upon probing during a programmed measurement with the 3D
touch probe. The length and radius of the stylus are not compensated for
these coordinates.
Coordinate axis Parameter
X axis Q115
Y axis Q116
Z axis Q117
IV axis Q118
Current tool radius compensation
The current tool radius compensation is assigned to parameter Q123 as
follows:
Current tool compensation Parameter value
R0 Q123 = 0
RL Q123 = 1
RR Q123 = 2
R+ Q123 = 3
R– Q123 = 4
