7.2.4 Calibrating Tool Offset Sensor

Calibrating the Sensor to Reference Point

The figure beside shows the interpretation of CONTACT parameters.

Let us examine the following example. Place a tool, the overhang of which is known in the tool holder. The tool overhang is indicated with XT, ZT on the diagram below. Execute an automatic tool length measure- ment as discussed in the previous chapter. On the diagram it is in directions X–, Z–. Read the selected X, as well as Z offset reg- ister values indicated with X(–),Z(–)on the diagram. Calculate and enter the values of the CONTACT parameter with the help of the following equation:

CONTACTX– = X(–)– XT

CONTACTZ– = Z(–)– ZT

The procedure can also be applied for the other buttons.
