Material Stretch Application
Again, a 12.00 inch part is desired. A Preset of
12.00 is entered into the control with a scale factor
of 1.0000 and a sample part is produced. When it
is measured, it is found to be 12.37 inches long.
The scale factor needed to produce a 12.00 inch
part is calculated by plugging these values into the
formula:
12.37
″
(Measured)
Scale Factor =
12.00
″
(Desired)
= 1.0308
When the scale factor of 1.0308 is entered into the
control, parts are produced at 12.00 inches as
desired. Since the material is stretched in the pro-
cess, each pulse received by the counter is worth
1.0308 counts. Thus, less than 1200 pulses need
to be received to produce each 12.00 inch finished
part and display 1200 counts.
