Machining the moving workpiece

After completing the static synchronisation with the workpiece, the actual machining process can be executed. Apart from the requirements regarding measured values (see Configuring the measuring system), the CNC makes a distinction between two different variants:

Machining operations on workpieces are always identical

When machining operations are identical, an endless loop can be programmed in an NC program. The endless loop always waits for the measured value of the next workpiece before starting the machining operation. At the end of the machining operation, the loop is restarted and the system waits for the measured value of the next workpiece.

Workpiece machining is a singular operation and dependent on the measurement

If a machining operation depends on the measurement of the current workpiece, an NC program template can be created for the machining operation. The differing sections in the NC program can then be described by V.E. variables which the PLC then correctly assigns after measuring the current workpiece. The template program is then started for each individual workpiece.
