Measuring Tools with the TT 110 Touch Probe

Input data

• MEASURE TOOL=0 / CHECK TOOL=1

Select whether the tool is to be measured for the first time or wheth-
er a tool that has already been measured is to be inspected. If the tool
is being measured for the first time, the tool length L in the central
tool file TOOL.T is overwritten by the delta value DL = 0. If you wish
to inspect a tool, the TNC compares the measured length with the tool
length L that is stored in TOOL.T. It then calculates the positive or
negative deviation from the stored value and enters it into TOOL.T as
the delta value DL. The deviation can also be used for Q parameter
Q115 (see page 12-18). If the delta value is greater than the permissi-
ble tool length tolerance for wear or breakage, the TNC will lock the
tool (status L in TOOL.T).

• CLEARANCE HEIGHT

Position in the tool axis in which there is no danger of collision with
the workpiece or fixtures.

• CUTTER MEASUREMENT 0=NO / 1=YES

Here you can choose measurement of single teeth.
