TwinCAT NC Flying Saw
“Flying saw” generally represents synchronisation of a slave axis with a master axis in motion. The master axis can be a real axis, a virtual axis, or some other external source of actual values. A simple example for a “flying saw” is a tool that processes a workpiece in continuous operation. To this end, the tool travels with the workpiece over a limited distance, synchronised in terms of velocity and position. After the task is complete, the tool returns to the starting position and is ready for the next task.
The PLC library contains blocks for programming this function under TwinCAT NC.
- synchronisation of the slave axis from any motion situation (stop, forward or reverse travel) with the master in motion
- simple synchronisation with the master velocity
- precise position synchronisation with the master axis (velocity and position)
- synchronous velocity can be set via a coupling factor
- optional return prevention as additional safety function
- superimposed section compensation during the synchronous phase for dynamic position correction
Typical applications for this functionality result can be found in transfer lines, printing and packing machines.
