7.1 Brief description
Channel-specific measuring
The trigger event programmed for channel-specific measuring in a part program block
initiates the measuring operation and specifies the measurement method used for the
measurement. The instructions apply to all axes programmed in this particular block.
Axial measurement
In the case of axial measuring, a measurement can be made from the part program and also
from synchronized actions. A measurement method, the encoder and the trigger events are
programmed. Whereby the trigger events are formed from the probe (1 and 2) and the
trigger criterion (rising/falling signal edge). Depending on the measuring task, several
measured values per measurement and trigger event can be recorded.
Preset actual value memory and scratching
The preset actual value memory is initiated by means of an HMI operator action. The
calculated frame can be written to system frame $P_SETFRAME. The setpoint position of an
axis in the WCS can be altered when the actual value memory is preset.
The calculation is performed in the NC when a PI service is activated via
● HMI operator action or a
● Part program command from the measuring cycles.
The term scratching refers to both the workpiece measurement and the tool measurement.
The measurements can be initiated via the
● HMI operator action or via
● Measuring cycles.
Communication with the NC takes place via predefined system variables.
