Table for tool cutting materials
Tool cutting materials are defined in the TMAT.TAB table. TMAT.TAB
is stored in the TNC:\ directory and can contain as many material
names as you want (see figure at upper right). The name of the cutting
material type can have a max. of 16 characters (including spaces). The
TNC displays the NAME column when you are defining the tool cutting
material in the TOOL.T tool table.
Table for cutting data
Define the workpiece material/cutting material combinations with the
corresponding cutting data in a file table with the file name extension
.CDT; see figure at center right. You can freely configure that entries
in the cutting data table. Besides the obligatory columns NR, WMAT
and TMAT, the TNC can also manage up to four cutting speed (V
C
)/
feed rate (F)combinations.
The standard cutting data table
FRAES_2 .CDT is stored in the directory TNC:\. You can edit
FRAES_2.CDT, or add as many new cutting-data tables as you wish.
If you change the standard tool cutting material table, you
must copy it into a new directory. Otherwise your
changes will be overwritten during a software update by
the HEIDENHAIN standard data. Define the path in the
TNC.SYS file with the code word TMAT= (see
“Configuration file TNC.SYS,” page 126).
To avoid losing data, save the TMAT.TAB file at regular
intervals.
If you change the standard cutting data table, you must
copy it into a new directory. Otherwise your changes will
be overwritten during a software update by the
HEIDENHAIN standard data (see “Configuration file
TNC.SYS,” page 126).
All of the cutting data tables must be stored in the same
directory. If the directory is not the standard directory
TNC:\, then behind the code word PCDT= you must enter
the path in which your cutting data is stored.
To avoid losing data, save your cutting data tables at
regular intervals.
