Cutting data table
Material tables
December 2001
The cutting data for specific tools are available from the tool manufacturer.
Cutting data tables have the file name extension .CDT.
Each line in the cutting data table contains the data for a specific combination
of workpiece and tool material. For milling cutters you can enter up to four
cutting speeds with the corresponding feed rates per teeth. In the tables of
the manufacturers these data are specified for different infeeds and for climb
and up-cut milling. For drills you enter a cutting speed with the corresponding
feed rate per revolution.
A standard cutting data table is saved in the root directory of the TNC (TNC:\).
You can add as many cutting data tables as desired.
If you change the standard cutting data table, you must copy the changed table
into another path. Otherwise your changes will be overwritten with
HEIDENHAIN standard data during the next software update:

In the system file TNC.SYS, use the code word PCDT= to enter the path in
which your cutting data tables are saved.
The workpiece materials used are defined in the table WMAT.TAB, the tool
materials in the table TMAT.TAB.
Standard tables are in the root directory of the TNC (TNC:\).
You can arbitrarily expand and change all tables.
If you change the tables, you must copy them into another path. Otherwise
your changes will be overwritten with HEIDENHAIN standard data during the
next software update:

In the system file TNC.SYS, use the code words TMAT= and WMAT= to
enter the path and file names of your tables.
