This
application utilizes the on-board PLC to control the machine. The test
system is performing leak and flow tests simultaneously over two fixtures.
This system also incorporates thread sensing presence attribute, and
poke-yoke style proof pins to check for the presence of holes. The display
also serves as an HMI, which shows machine status. For example, if a thread
were missing, the screen would show a Thread Fault.
Two
cavities need testing simultaneously, but common wall leakage needs to be
detected. Through advanced techniques and custom programming, a total test
time of 14 seconds and a Gage R & R of 4% is achieved.
A PLC
controlled machine assembles and gages multiple styles of parts. The
ViCATS-LTS performs a leak and flow test on each part. Part volumes range
from ¼ liter to almost 3 liters, depending on part style. Total test time
for largest part including leak and flow testing is 6 seconds.
Turbine
shaft cross-drilled holed are simultaneously flow tested for restriction
and are leak tested sequentially. The on-board PLC controls the machine
while a graphical interface communicates test information to the operator.
