rs Unit of measurement for dimensions in the
program: Q113
During nesting with PGM CALL, the value of the parameter Q113
depends on the dimensional data of the program from which the other
programs are called.
Tool length: Q114
The current value for the tool length is assigned to Q114.
The current value for the tool length is assigned to Q114. Q114 is
calculated from:
 The tool length L (tool table or TOOL DEF block)
 Delta value DL from the tool table
 Delta value DL from the TOOL CALL block
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 touch probe. The coordinates refer to the datum point that is
active in the Manual Operation mode.
The length of the stylus and the radius of the ball tip are not
compensated in these coordinates.
Dimensional data of the main program Parameter value
Metric system (mm) Q113 = 0
Inch system (inches) Q113 = 1
The TNC remembers the current tool length even if the
power is interrupted.
