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.
Data required for the tool table
n
Tool radius—column R (DR)
n
Number of teeth (only with tools for milling)—column CUT
n
Tool type—column TYPE
n
The tool type influences the calculation of the feed rate:
Milling tool: F = S · f
Z
· z
All other tools: F = S · f
U
S: Spindle speed
f
Z
: Feed per tooth
f
U
: Feed per revolution
z: Number of teeth
n
Tool cutting material—column TMAT
n
Name of the cutting data table for which this tool will be used—
column CDT
n
In the tool table, select the tool type, tool cutting material and the
name of the cutting data table via soft key (see “Tool table: Tool data
for automatic speed/feed rate calculation.,” page 141).
