Determining Maximum Stitch Bead Length - We determined this value
using the following general rule:
• Duration length (in seconds) x
0.20-
Max. stitch bead length (in
seconds)
In this example, the maximum stitch bead length is 0.158 seconds:
•
0.788x
0.20-0.1576
seconds (157.6 ms)
We rounded the value to 0.158 seconds {158 ms). The PC40 stitch
capability would allow us to specify stitch beads as long as 0.158
seconds each.
However, we wanted more and shorter stitch beads for our application.
We ran
several test patterns and
got
the following results.
Stitch
Bead Lengths
Number
of
Beads
at
50% Coverage
0.050 8
0.060 7
0.070 6
0.082

Based on the test patterns and our
application, we specified beads
0.050 seconds long at 50% coverage. These values were recorded on
the pattern log (Figure 4.1 0).
Stitch

was programmed and noted on the pattern log for channel 1.
