Approach the workpiece in the X or Y direction and perform
scratching with the spindle rotating in the opposite direction (see
Sec. "Traversing the machine axes").
Measuring radius/diameter
Specify the setpoint position X0 or Y0 of the workpiece edge.
Press the "Set radius" or "Set diameter" softkey.
The tool radius or diameter is calculated automatically and entered in
the tool list.
If you want to use a fixed point as the reference point in manual
measurement of the tool length, you must first determine the position
of the fixed point relative to the machine zero.
You can use a mechanical test socket as the fixed point, for example.
Mount the test socket on the machine table in the machining space of
the machine. Enter zero as the distance.
But you can also use any fixed point on the machine in combination
with a distance gauge. Enter the thickness of the plate in "DZ".
To calibrate the fixed point either use a tool of known length (i.e. the
tool length must have been entered in the tool list) or the spindle
directly.
The position of the fixed point may have already been determined by
the machine manufacturer.
Please refer to the machine manufacturer's instructions.
