Compensation-value table
The laser measuring cycle 598 automatically creates the
compensation value table. In this regard, please note the
documentation for laser measuring cycles.
If you wish to create and fill the compensation value table with data
yourself, proceed as follows:
 To call the file management, press the PGM MGT key
 Enter any file name with the TAB extension and confirm with the
ENT key. The TNC displays a pop-up window with permanently
saved table formats
 Use the arrow key to select the table format 3DTOOLCOMP.TAB and
confirm with the ENT key. The TNC opens a new table containing
only one line and those columns that are required for the function of
3D-ToolComp
The compensation value table is a "freely definable table."
See "Freely definable tables" on page 475 for further
information about working with freely definable tables.
If the TNC does not show a pop-up window or the
3DTOOLCOMP table format when you open a new .tab file, you
must first use the COPY SAMPLE FILES function to
generate the table formats (see "Copying sample files" on
page 665).
The TNC evaluates the following columns of the compensation value
table:

ANGLE:
Angle at the tool's cutting edge to which the determined
compensation value NOM-DR2 belongs. Input range: 0° to 180°; for
radius cutters the angle values are between 0° and 90°

NOM-R2:
Nominal radius R2 of the tool. The TNC uses the values from NOM-R2
only to determine the end of the compensation value table: The end
of the table is the line where the value=0 is entered in the NOM-R2
column

NOM-DR2:
Deviation from the nominal value (oversize) and negative values
(undersize) are permitted
The TNC evaluates a maximum of 50 lines in a
compensation value table.
The TNC evaluates negative angle values from the ANGLE
column but compensates the compensation values
always in the positive angle range of the tool.
