Creating a new cutting data table
8 Select the Programming and Editing mode of operation.
8 Press the PGM MGT key to select the file manager.
8 Select the directory where the cutting data table is to be stored.
8 Enter any file name with file name extension .CDT, and confirm with
ENT.
8 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—column R (DR)
„ Number of teeth (only with tools for milling)—column CUT
„ Tool type—column TYPE
„ 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
„ Tool cutting material—column TMAT
„ Name of the cutting data table for which this tool will be used—
