Creating the program blocks with the path function keys

The gray path function keys initiate the plain language dialog. The TNC
asks you successively for all the necessary information and inserts the
program block into the part program.

Example—programming a straight line:

Initiate the programming dialog, e.g. for a straight
line.

Enter the coordinates of the straight-line end point.

Select the radius compensation (here, press the R0
soft key—the tool moves without compensation).

Enter the feed rate (here, 100 mm/min), and confirm
your entry with ENT. For programming in inches,
enter 100 for a feed rate of 10 ipm.

Move at rapid traverse: press the FMAX soft key

To traverse with the feed rate defined in the TOOL
CALL

block, press the F AUTO soft key.

Enter a miscellaneous function (here, M3), and
terminate the dialog with ENT.

The part program now contains the following line:

COORDINATES?

RADIUS COMP.: RL/RR/NO COMP.?

FEED RATE F=? / F MAX = ENT
