Creating a new cutting data table.
ú
Select the Programming and Editing mode of operation.
ú
To select the file manager, press the Taste PGM MGT key.
ú Select the directory where the cutting data table is to be stored.
ú
Enter any file name with file name extension .CDT, and confirm
with ENT.
ú
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
■
Tool radius – under R (DR)
■ Number of teeth (only with tools for milling) – under CUT.
■
Tool type – under TYPE
The tool type influences the calculation of the feed rate:
Tools for milling: F = S • f
Z
• z
All other tools: F = S • f
U
S = spindle speed
f
Z
= feed rate per tooth
f
U
= feed rate per revolution
z = no. of teeth
■
Tool cutting material – under TMAT
■
Name of the cutting data table for which this tool will be used -
under CDT
In the tool table, select the tool type, tool cutting material and the
name of the cutting data table via soft key (see „5.2 Tool Data“).
