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), a negative
delta value describes a tool undersize (DR<0). Enter the delta
values when you are programming with TOOL CALL.
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. When the tool table is
active, enter tool numbers greater than 99
(dependent on MP7260)
ú Enter the tool length: Enter the compensation
value for the tool length.
ú Enter 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“.
