Now select "Calculate". Once you press ENTER, Feed Advisor calculates your
acceleration rate. This message quickly flashes on the screen.
PLEASE WAIT … CALCULATING PARAMETERS
Then Feed Advisor tells you if the feed length and feed arc you entered are valid for that
press speed. For instance, if Feed Advisor determines that the feed has plenty of time to
complete based on the values entered, you will see this message at the bottom of the
"Feed Advisor" screen:
THE MATERIAL WILL BE FED UP WELL BEFORE
THE FEED ARC IS COMPLETED.
This means that the feed will end well before the end of the feed arc you have entered.
If you see this message:
THE MATERIAL WILL BE FED UP JUST AS
THE FEED ARC IS COMPLETED.
… this means that the feed will end just as the feed arc is completed. This is the
optimum condition. If you entered values that will not allow the feed to complete before
the end of the feed arc, you see this message:
THE MATERIAL CANNOT BE FED UP IN TIME.
MORE TIME MUST BE ALLOWED.
In this case, recheck your values. It might just be a matter of lengthening the feed arc if
that will not affect other actions, such as part transfer or part cut off. If you cannot do
that, your other option is decreasing press speed. In any case, revise your figures if
ProCam 1500 gives you a warning. Then "calculate" Feed Advisor again.
When you get a good calculation, press the RESET key.
You will see the acceleration
rate and maximum run speed for your feed setup are automatically revised by Feed
Advisor. In our example (Figure 3-15), the acceleration rate is 40%. This means that the
feed is comfortably within an acceptable acceleration range and maximum run speed.
