Calling Q parameter functions
When you are writing a part program, press the Q key (in the
numeric keypad for numerical input and axis selection, below the
+/- key). The TNC then displays the following soft keys:
Soft key Function group
Basic arithmetic (assign, add,
subtract, multiply, divide,
square root)
Trigonometric functions
Function for calculating
circles
If/then conditions, jumps
Other functions
Entering formulas directly
Function for machining
complex contours
The TNC shows the soft keys Q, QL and QR when
you are defining or assigning a Q parameter. First
press one of these soft keys to select the desired
type of parameter, and then enter the parameter
number.
If you have a USB keyboard connected, you can
press the Q key to open the dialog for entering a
formula.
