is run using the start key. This type of
routing operation takes around 20
minutes to complete and requires no
further involvement by the machine
operator.

Having launched OSS Draw, the first
step is to draw a box or boarder on
the screen to indicate the overall area
of the work. This can be either a
simple rectangular boarder or a more
decorative one.
This border then needs to have a
depth assigned to it. This is done by
using colours to define the depth of
each area.
The logo is then created using the
drawing tools within OSS Draw.
and blue areas of
the logo and the
lettering have been assigned a depth
of 5mm and the green area assigned a
depth of zero. The same dialogue box
lets you specify whether a letter or
object is engraved or routed through
the material.
The cutter profile that will be used
can now be defined. With lettering,
particularly serifed fonts, the cutter
used needs to have a small diameter,
perhaps 3mm. However, to achieve a
5mm cutting depth this will have to be
routed in several passes.
A simulation of the cutting path is
now drawn on screen. Having then
created a G-code file of the sign ready
for the CNC 860 to cut, the file is
downloaded to the CNC 860.
Sign-writing is just one of the
many complex and wide ranging
routing operations that can be
carried out using the OSS and
CNC 860 package. OSS also has a
range of tools for drawing component
shapes and profiles directly or with an
electronic sketchpad (graphics tablet).
Vacuum Clamping
To reduce the through-put time for
this kind of operation, the CNC 860
can also be used with a vacuum bed.
