Refere nce sw itch and ho mi ng
If the cutting edge is not aligned correctly, use the C + / C button to turn the knife to the correct
angle. Note the displayed C coordinate and subtract it from the value "Reference switch position" in
the axis parameters (Configuration - Machine - Axis parameter, select axis: C For example, if
"Reference switch position" was -55 before, and the coordinate display for exact angular orientation
is +3.5, then you must enter -55 - 3.5 = -58.5. Then carry out a new reference run and repeat the
check of the angle.
No CAM program nec essary
For cutting with tangential knife, it is not absolutely a CAM program necessary. You can import the
lines to be cut directly as an HPGL or DXF file and only need to specify the plunge depth and
security height for trips over the material. Alternatively, you can also use a G-code program. This
should only be 2-dimensional, this means it consists of a sequence of rapid traverse positioning
(G0) above the material, an insertion movement (G1 with Z movement vertically downwards), one
or more XY movements within the material (G1, G2 or G3 without Z) and a lifting movement (G1
with Z movement vertically upwards) and any number of repetitions.
Sharp cor ners or not
It is important that the drawing has tangent-continuous transitions at all points where liquid is to be
passed through. Wherever sharp-edged lines about each other, the control automatically generates
an additional and insertion movement. This is intended if, for example, a sharp-edged rectangle is
to be cut and prevents the unsightly tearing of the material or even a breakage of the blade, which
could happen if the blade had to be turned too large an angle within the material. If the blade is not
to be taken out of the material, the corners of the rectangle must be rounded with quarter-circle arcs.
Clean draw ings
It is also important that the drawing is made carefully and that the starting points of the following
lines are exactly at the end points of the preceding lines. Gaps or overlaps not only lead to jerky
movements, but because of the step-like direction changes also to unnecessary excavation, turning
and insertion movements. The limit values for the angles between successive lines, from which a
stop or an lifting / insertion movement is inserted, can be set in the machine parameters on the
special page.
