Example of on-the-fly parting
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. WCS
X1 axis: Machine axis of extruded material, MCS
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.
Actions
