Measuring A Tool With A Magnifying Glass - Siemens SINUMERIK 828D Operating Manual

Measuring a tool with a magnifying glass

You can also use a magnifying glass to determine the tool dimensions, if this is available on
the machine.
In this case, SINUMERIK Operate calculates the tool offset data from the known positions of
the tool carrier reference point and the cross-hairs of the magnifying glass.
Note
Lathes with B axis
For lathes with a B axis, execute the tool change and alignment in the T, S, M window before
performing the measurement.
