PART 1 – SYSTEM OVERVIEW
SPEED
For speeds less than 1000 mm/min (40 in/min) a corner radius of 2.5mm (0.1 in.) is
recommended. For speeds above 1000 mm/min the radius should be increased based on
the machine performance. This will be directly related to the drives selected and the
frame weight and stability.
CORNERS
The smallest angle which can be traced (without a corner radius) is 90
°
. If an angle less
than this is required, or if kerf is to be used, the template must have a corner radius as
described under
Speed above. If a corner radius is not provided an alternative solution is
to use corner slowdown.
CORNER SLOWDOWN
The Replicator CCD has two modes for corner slowdown:
•
Automatic Slowdown
•
Corner Marker Slowdown
Corner slowdown modes are selected by the yellow tracer function pushbuttons as
described in the “Replicator Trace Function Activation Table” in Part 2.
The corner slowdown speed is set using the Corner Speed pot, but is never greater than
the speed set by the Run Speed pot and the High / Low / Off Speed switch.
AUTOMATIC CORNER SLOWDOWN
When the Automatic Corner Slowdown mode is active, the tracer will slowdown under
certain template conditions. Typically, these conditions are when the tracer approaches:
1. Any radius of 8 mm (5/16”) or less.
2. Any corner of 135º or less.
CORNER MARKER SLOWDOWN
With the Corner Marker Slowdown mode active, the tracer will slow down in areas
where the template is prepared as follows.
Increase the width of the line to 4mm (0.160 in.) at each corner or location where
slowdown is desired, as shown in Figure 1.3 below. Note that the line must be widened
on the edge not followed by the tracer.
Slowdown begins when the wide part of the line is encountered by the tracer. Speed will
decrease from the machine feedrate to a value set by the Corner Speed pot, if the
slowdown began soon enough. This means that the best length of the widened line
depends on the machine performance.
