Tip of the Day 175: Full Integrals vs. Fill and Pack Integral

In Tip #174 you saw how Fill and Pack Integral could be useful for monitoring dimensions in very thin-wall, fast freezing parts. In that discussion we used End of Cavity as the indicator, assuming that the dimension near the end of the cavity was most important.A...

Tip of the Day 150: The Mystery of the “Integral” (part 3)

In tip #148 we explained that the integral is an area or “area under the curve” as we say in class. At a recent training event Rajen was trying to answer a couple of tough remaining questions.1. “Why are the units shown as psi-seconds?” (or bar-seconds)    Just as we...

Tip of the Day 149: The Mystery of the “Integral” (part 2)

With an understanding of what an integral IS, the popular next question is “How do you compute it? I know how to figure the area of a rectangle or triangle but what is formula for the area of this:  ?”Answer: Let the eDART™ calculate it.Those with an itch to know...

Tip of the Day 148: The Mystery of the “Integral” (part 1)

We regularly struggle to explain what an “integral” is and where it comes from. Integrals are numbers calculated by the eDART that are particularly useful for detecting changes in part weight or dimensions.Generally we say an integral is the “area under the curve,”...
