You can enter the tool radius R directly.

Delta values for lengths and radii

Delta values are offsets in the length and radius of a tool.

A positive delta value describes a tool oversize (DR>0). If you are
programming the machining data with an allowance, enter the
oversize value in the TOOL CALL block of the part program.

A negative delta value describes a tool undersize (DR<0). An
undersize is entered in the tool table for wear.

Delta values are usually entered as numerical values. In a TOOL
CALL block, you can also assign the values to Q parameters.

Input range: You can enter a delta value with up to ± 99.999 mm.

Entering tool data into the program

The number, length and radius of a specific tool is defined in the
TOOL DEF block of the part program.

ú

To select tool definition, press the TOOL DEF key.

ú

Enter the Tool number: Each tool is uniquely identified
by its number.

ú

Enter the tool length: Enter the compensation value
for the tool length.

ú

Enter the tool radius: Enter the compensation value
for the tool radius.

During the dialog, you can take the values for length and
radius directly from the position display with the soft
keys „CUR.POS X, CUR.POS Y or CUR.POS Z“.

If you use the black key for actual-position capture, the
TNC saves the value of the active tool axis for the tool
length. If no tool axis is active, the TNC saves the value
of the axis that has been defined in the probing function
calibration menu as the touch probe axis.
