1.3 TEMPLATE PREPARATION
1.3.1 INTRODUCTION
The Replicator CCD tracing system uses a template, a full-scale drawing of the part or
hole to be cut. The system can trace a line drawing or a silhouette. See the figure below
showing these two drawing types.
Figure 1.2 – Template Types
The system can trace a black line on white paper in Edge Mode or Centerline Mode. It
can also trace a silhouette (edge) template in Edge Mode only.
For best performance the contrast of the line or edge template should be as high as
possible. If various shades of gray are encountered, or if the patterns are not kept clean,
tracing performance will deteriorate accordingly.
Black ink on white paper has proved to provide the best overall tracing regarding both
accuracy and reliability.
1.3.2 INSTRUCTIONS FOR TEMPLATE PREPARATION
SHAPE
A line template usually has the same size and shape as the part or hole to be cut, at the
outside edge of the template or along the centerline of the template. In edge mode tracing
with the Tracer Kerf pot set to zero, the center of the tracing head and the center of the
torch follow the outside edge of the template line. In centerline mode tracing with the
Tracer Kerf pot set to zero, the center of the tracing head and the center of the torch
follow the center of the template line.
A template that will always be used with the same value of kerf can be enlarged by half
this kerf value. Then it can be run with the Tracer Kerf pot set to zero and the part will
cut to the correct size.
LINE WIDTH
For best performance, template lines should be a minimum of 0.7mm (0.028 in.) in
width.
