Measuring A Tool With A Magnifying Glass - Siemens SINUMERIK 840D sl Operating Manual

Setting up the machine
4.5 Measuring the tool
Sequence
The calibrating tool must be a turning tool type (roughing or finishing tool). Cutting edge
positions 1 - 4 can be used for the tool probe calibration. You must enter the length and the
radius or diameter of the calibrating tool in the tool list.
Calibrate the probe in all directions in which you wish to subsequently perform measurements.
Procedure
4.5.4

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.

1. Change the calibrating tool.
2. Select the "JOG" mode in the "Machine" operating area.
3. Press the "Meas. tool" and "Calibrate probe" softkeys.
4. Press the "X" or "Z" softkey, depending on which point of the tool probe
you wish to determine first.
5. Select the direction (+ or -), in which you would like to approach the tool
probe.
6. Position the calibrating tool in the vicinity of the tool probe in such a way
that any collisions can be avoided when the first point of the tool probe is
being approached.
7. Press the <CYCLE START> key.
The calibration process is started, i.e. the calibrating tool is automatically
traversed at the measurement feedrate to the probe and back again. The
position of the tool probe is determined and saved in an internal data area.
8. Repeat the process for the other other points of the tool probe.
