Introduction - Measuring in JOG and AUTOMATIC

Measuring in JOG
When measuring in JOG mode (setup), the machine is prepared for machining. This involves
determining the dimensions of the workpiece and the tool, which are still unknown.
Manual measurement is used to prepare the machine for machining.
Manual measurement is used to determine unknown workpiece or tool geometries.
The operator interacts with the machine during manual mode in order to perform the mea-
surement.
Measuring in AUTOMATIC
When measuring in AUTOMATIC mode (in-process measurement), workpiece tolerances are
determined within the production process and the tool parameters are monitored. The nominal
dimensions of the tool and workpiece are already known.
Automatic measurements are performed to check that the workpiece measurements conform
to specifications.
Automatic measurements are performed to correct known workpiece and tool geometries.
The measurement is performed by calling a measuring cycle in the machining program.
Measuring cycles for all measuring tasks
The SINUMERIK features an extensive pool of practical measuring cycles for measuring tasks in
JOG and AUTOMATIC modes. These measuring cycles enable you to measure workpieces and
tools using a graphically supported process.
The measuring tasks are carried out with touch trigger or non-switching probes and dynamome-
ters or laser measuring systems.
