Tool measurement

coordinate system

December 2001

If the tool is to be measured in a tilted position other than that in which the

tool touch probe was calibrated, set MP6500 bit 13 = 1.

Tool measurement with TT 130

%xxxxxxxxxxxxx

0: Tool is measured in the tilt position in which the tool touch

probe was also calibrated

1: Tool is measured in another tilt position

If the tool is not measured in the same tilt position as that in which the tool

touch probe was calibrated, ensure that the tool is perpendicular to the

contact plate!

With MP6500 bits 5 and 6, specify whether the NC program should stop

when the breakage tolerance is exceeded. M4063 is always set when the

breakage tolerance is exceeded.

With bit 11, specify whether the result of "tool checking" measurement is

to be entered in the tool table.

Bit 5 – NC stop during "tool checking"

0: The NC program is not stopped when the breaking tolerance

1: If the breakage tolerance is exceeded, the NC program is

stopped and the error message "tool broken" is displayed

Bit 6 – NC stop during "tool measurement"

0: The NC program is not stopped when the breakage tolerance

1: If the breakage tolerance is exceeded, the NC program is

stopped and the error message "touch point inaccessible" is

Bit 11 – "Tool checking" and changing in the tool routine

0: After "tool checking" the tool table is changed

1: After "tool checking" the tool table is not changed
