Measure workpiece (turning)

3.2.1

General information

The measuring cycles below are intended for use on turning machines.
Note
Spindle
Spindle commands in the measuring cycles always refer to the active master spindle of the
control.
When using the measuring cycles at machines with several spindles, then the spindle involved
must be defined as master spindle before the cycle call.
Note
Precise measurement is only possible with a probe calibrated under the measurement
conditions, i.e. working plane and measuring velocity are the same for both measurement and
calibration.
If the probe is used in the spindle for a driven tool, the spindle orientation must also be
considered. Deviations can cause measuring errors.

Diameter programming, measuring system
The measuring cycles used in turning work with the current plane G18.
Value specifications of the transverse axis (X) of the measuring cycles used in turning are
performed in the diameter (DIAMON). The measuring cycles used in turning
CYCLE974 and CYCLE994 ) also work internally with active diameter programming (DIAMON).
The measuring system (basic system) of the machine and the workpiece can be different.
The G700 command should be used when measuring the workpiece in INCHES on a metric
machine.
The G710 command should be used when measuring the workpiece in mm on an "INCH"
machine.
For information regarding measurement in conjunction with a 3rd axis, see Chapter Extended
measurement (Page 105).

data used with regard to the measuring cycle versions 7.5, 2.6 and 4.4 can be found in the
