5.7 Axis couplings via synchronized actions
Expansion options
The example above can be expanded by the following components:
• Introduction of a Z axis to move the grinding wheel or workpiece from one non-circular
• Table switchovers, if the cams for inlet and outlet have diferent contours.
• Dressing of grinding wheel by means of online tool offset acc. to Subsection "Online tool
5.7.3
On-the-fly parting
Task assignment
An extruded material which passes continuously through the operating area of a cutting tool
must be cut into parts of equal length.
X axis: Axis in which the extruded material moves, WKS
X1 axis: Machine axis of the extruded material, MKS
Y axis: Axis in which cutting tool "tracks" the extruded material
It is assumed that the infeed and control of the cutting tool are controlled via the PLC. The
signals at the PLC interface can be evaluated to determine whether the extruded material
and cutting tool are synchronized.
