Programming a simple contour
The contour shown to the right is to be milled once to a depth of
5 mm. You have already defined the workpiece blank. After you
have initiated a dialog through a function key, enter all the data
requested by the TNC in the screen header.
Call the tool: Enter the tool data. Confirm each of
your entries with the
ENT key. Do not forget the
tool axis
Press the
L key to open a program block for a
linear movement
Press the left arrow key to switch to the input
range for G codes
Press the G0 soft key if you want to enter a rapid
traverse motion
Retract the tool: Press the orange axis key Z in
order to get clear in the tool axis, and enter the
value for the position to be approached, e.g. 250.
Press the
ENT key
Radius comp.: RL/RR/no comp.? confirm with the
ENT key: Activate no radius compensation
Confirm
Miscellaneous function F=? with the END
key: The TNC stores the entered positioning block
Press the
L key to open a program block for a
linear movement
Press the left arrow key to switch to the input

3000 mm/min and confirm with the
ENT key
Miscellaneous function M? Switch on the spindle
and coolant, e.g.
M13 and confirm with the END
key: The TNC stores the entered positioning block
Enter
26 to move to the contour: Define the
