Knife Offset - Intec ColorCut SC5000 Series User Manual

9.1 Knife Offset

The Intec ColorCut series of cutters use a contour-cutting blade (sometimes refered
to as a 'drag knife') to accurately cut your shapes. The blade revolves/rotates around
its centre as the carriage moves following the cutting path and as the Tool Carriage
changes direction.
Blade will turn on this axis
When the blade reaches a corner its axial centre [the point around which it rotates]
arrives before the cutting point and unless there is some means of causing it to do
so, the cutting part of the blade would never reach the corner and would start to turn
as the cutter changed direction thus creating a radius instead of a sharp corner.

Intec ColorCut Digital cut engines have a built in routine to manoeuvre the blade in a
way that compensates for this, it is known as Knife Offset. BUT ONLY IF YOU SET
IT CORRECTLY.
Setting this correctly and checking it each time you change blades is important
because Intec supplies a range of blades to enable the cutting of different media
and various thickness's. Some blades have a thicker shaft than others. This means
the distance from the blade's centre to the cutting point (the Knife Offset) will be
different depending upon the blade. The Knife Offset value is used by the software
to compensate for the distance from the point at which a blade cuts to the point
around which it rotates.
