3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 12100-1:2003 and the following
apply.
3.1
vertical panel sawing machine
machine designed for cutting panels where the work piece is supported in a near vertical plane during cutting.
The saw unit is mounted in front of the workpiece support (example see Figures 1). The cut takes place either
in a single straight vertical line by moving the saw unit along the moving beam or in a single horizontal line by
moving the moving beam along the work piece support. The work piece is manually loaded and unloaded. The
machine may have any of the following main features:
a) the facility for scoring;
b) an angle cutting device;
c) a middle support device;
d) a programmable stop for parallel vertical cuts;
e) the facility for using grooving tools

3.2
vertical panel sawing machine with hand feed
machine where the saw unit incorporating the saw blade is manually guided along the moving beam for
vertical cuts or manually guided together with the moving beam along the workpiece support for horizontal
cuts
3.3
vertical panel sawing machine with integrated feed
machine where the saw unit incorporating the saw blade has integrated feed for its vertical movement along
the moving beam and / or for its horizontal movement by moving the moving beam along the work piece
support. The saw blade is automatically projected through the work piece during the cutting stroke and then
retracted together with the saw unit from the work piece to its rest position followed by the return stroke of the
saw unit to its rest position
3.4
manual loading
where the operator puts the work piece on the workpiece support i.e. there is no intermediate loading device
to receive and transfer the work piece from the operator to the cutting position
3.5
manual unloading
where the operator removes the work piece from the workpiece support i.e. there is no intermediate unloading
device to transfer the work piece from the cutting position to the operator
