2.3.1 Typical motion profiles
Flying saws are used to cut continuous material to length if the material cannot be stopped during the cutting
process.
The mechanical design includes a saw carriage that moves in the direction of the material. The carriage
moves in synchronism with the material during the cutting process and returns to its initial position once the
cut has been made.
The advantage is an improved number of cycles and a better use of resources in a production process.
Therefore it is necessary to synchronise tools and workpieces with reference to their position and speed
such that the tool can be used in the same way as if the workpiece were stationary. An example for such an
application is a cross-saw which cuts across the material (at an angle of 90° to the workpiece) while it is
transported.
The picture above shows a "Flying saw" application. Continuous material such as extruded material has to
be cut to length. As soon as the cutting process starts, the saw is synchronised to the speed of the material
to be cut to length. During the cutting process, the saw runs in synchronism.
At the end of the process, the saw moves back to its initial position.
