2 – 46 HEIDENHAIN Technical Manual TNC 426, TNC 430
n With MP6500 bit 4 you can define whether speed should be limited to
1000 rpm during tool measurement with TT.
n MP6500 bit 9: Automatic determination of the basic rotation for tool
measurement with the cubical probe contact
n W760: Angular misalignment of the tilting axes for automatic adjustment of
touch probe center misalignment
n The calibration data of the TS can be saved in the tool table by soft key.
n Cycle 31 to 33 (tool measurement) were expanded by the input field “Q
parameter for result.”
n With MP6500 bit 5 and bit 6 you can define the reaction to tool breakage.
n FN17, FN18 ID990 NR1 behavior during programmed probing
n FN17: ID210 NR6 Tilting the working plane during program run
active/inactive
