Working with automatic speed/feed rate calculation
If it has not already been entered, enter the type of workpiece
material in the file WMAT.TAB
If it has not already been entered, enter the type of cutting
material in the file TMAT.TAB
If not already entered, enter all of the required tool-specific data
in the tool table:
■ Tool radius
■ Number of teeth
■ Tool type
■ Tool cutting material
■ The cutting data table for each tool
If not already entered, enter the cutting data in any cutting data
table (CDT file)
Test Run operating mode: Activate the tool table from which the
TNC is to take the tool-specific data (status S).
In the NC program, set the workpiece material by pressing the
WMAT soft key.
In the NC program, let the TOOL CALL block automatically
calculate spindle speed and feed rate via soft key
Changing the table structure
Cutting data tables constitute so-called „freely-definable tables“ for
the TNC. You can change the format of freely definable tables by
using the structure editor.
Calling the structure editor
Press the EDIT FORMAT soft key (2nd soft-key level). The TNC
opens the editing window (see figure at right), in which the table
structure is shown ”rotated by 90°.” In other words, a line in the
editing window defines a column in the associated table. The
meanings of the structure commands (header entries) are shown in
the table at right.
Exiting the structure editor.
Press the END key. The TNC changes data that was already in the
table into the new format. Elements that the TNC could not convert
into the new structure are indicated with a hash mark # (e.g., if you
have narrowed the column width).
