2.1.3 Properties and features of the core “flying saw” functions
The following properties and features were taken into account when
implementing the core functions, and can also be used in a user program
that you generate yourself:
• Precisely synchronizing at a specific position
The "flying" axis is accelerated to the velocity of the material web so
that this reaches this velocity above a position on the material that can
be specified.
• Flying axis
The "flying" axis and the material move at the same velocity while
sawing/cutting.
• The starting position of the "flying" axis can be set
The starting position of the "flying" axis between two cuts can be set
using a parameter at the core function.
• "Cutting" at a print mark
The synchronous position is detected using a measuring probe and
print mark.
• "Cutting" to length
The synchronous position is calculated from the distance that the
material has moved through.
• Immediate cut
A cut is initiated by an operator function independently of the distance
that the material has moved. (This function is only possible for "cut" to
length!)
• Creating a gap
After a cut has been made, the cutting unit additionally moves the cut
material in the direction in which the material is moving until a certain
distance is reached to the rest of the material. This distance can be
specified. The cutting unit only returns to its starting position after this
operation has been completed.
• Asymptotic synchronizing
The “flying” axis is accelerated to the velocity of the material web
without overshoot in velocity.
• Gearing Ratio
Ratio between measured and effective velocity of the material web.
