If the
VariAngle unit
is used as a regular knife tool
(0 degrees cut) to cut out a simple rectangle, the
difference between top and bottom might look
like the illustration above. Note that if length is
added or removed from a line, both sides will be
affected.
If the same shape is cut at an angle, e.g. 45
degrees, the difference might look like the
illustration above (dashed line refers to opposite
side). Note that the lines might not connect to
eachother on the top-side. This might make it
hard to separate the rectangle from the frame.
Here the
Knife Overcut
function can be helpful.
For 0 degrees cuts, the “overcuts” can be avoided fully by starting in the corner of each line and cutting
towards the middle. In the
User manual
for iPC
, section “10.1.7. Optimize for production”, there are
more details about this.
Circle Adjustment
Curved geometries, like circles and arcs, can be cut with the
VariAngle unit
, both at an angle and when
performing regular straight cuts.
Note: Use caution when cutting arcs or circular
geometries. If the radius is too small or the board-
material too tough, it might cause the blade to
break or the knife to cut into the table top. There
is no warning for minimum radius, as this will be
material and
notch angle
dependent. It is highly
recommended to reduce speed and acceleration
when cutting arcs and curves.
To increase the quality of the circular cuts, the
Circle Adjustment
setting can be used. The setting
will change the theoretical lag value of the knife and therefore rotate a little before or after the original
setting. This might lead to a cleaner finish, but it could change the radial value of the arc.
Rotational Compensation
Because of the available use cases for the
VariAngle unit
, the knife blades are quite long. For some
materials this will lead to blade flexing. The
Rotational compensation
function can reduce the flexing
of the knife blade by preloading it. This can increase the quality of the cut and in some cases make it
easier to cut through challenging materials.
Note:
Use caution when applying this function, as too much preloading might cause the knife blade
to break or cut into the table top. Further, this setting is only suitable for cutting at an angle, not for 0
degrees cuts.
