Measuring A Tool With The B Axis - Siemens SINUMERIK 840D sl Turning Operating Manual

Measuring a tool with the B axis

When measuring manually, traverse the tool manually to a known reference point in order to
determine the tool dimensions in the X and Z directions. The control system then calculates the
tool offset data from the position of the tool carrier reference point and the reference point.
To determine the tool dimensions, the orientation, i.e. the β angle, must be specified.
The γ angle input box is also provided for turning tools.
Reference point
The workpiece edge is used as the reference point when measuring length X and length Z. The
chuck of the main or counterspindle can also be used when measuring in the Z direction.
Specify the position of the workpiece edge during the measurement.
β angle
In order to measure milling and turning tools, you can select the two main settings β = 0° and β
= 90° and a value input field.
γ angle
In order to measure turning tools, you can select the γ angle 0° and 180°.
