On the right half of the screen, the TNC displays various table
formats (machine-dependent, see example in figure at right). These
tables differ from each other in the number of cutting speed /
feed rate combinations they allow. Use the arrow keys to move the
highlight onto the table format you wish to select and confirm with
ENT. The TNC generates a new, empty cutting data table.

n

Tool radius—column R (DR)

n

The tool type influences the calculation of the feed rate:
Milling tool: F = S · f

All other tools: F = S · f

U

S: Spindle speed
f

Z

: Feed per tooth

f

U

: Feed per revolution

z: Number of teeth
