Hi, I'm Drew Klaber with Mitutoyo America Corporation.
I'm here with Jeremy Banks, who's our National Data Management Sales Specialist.
And today we're going to be talking about Derive Characteristics and MeasurLink.
So, Jeremy, I've run across a few applications lately
where a customer may have a part that they're measuring
and they're doing a couple, let's say diameter measurements.
And once these measurements are done, they'll get the calculator out,
figure out maybe an average or maybe they're doing maximizers.
There's an additional calculation that they're doing.
Is there a way that we can just have MeasurLink automatically do that calculation for us?
Yes. So there's a function of MeasurLink called Derived Characteristics.
And I'll show you how to set that up so we can do an average. Perfect.
So, Drew, in your example, the customer is measuring this diameter in X and Y.
So, for example, when you measure the diameter in X,
and then I'm going to rotate the part and measure the diameter of Y,
and then your customers are required to average those two readings,
to get a third characteristic, correct? Correct.
OK. So let me show you how to set that up.
So, Drew, the first thing I need to do is create my Derived Characteristic.
Now, this is going to be average.
So inside of my Part Library, I'm going to add a New Characteristic.
And I'm going to call it Average.
And I'm going to change it from a Variable to a Derived.
To Derive meaning it will automatically calculate.
Correct. So I'm going to click off and then I'm going to click back on Average.
And now I can see that I have an Equation tab.
Now I'm going to build the equation for average.
You always have to start with the characteristic name.
That's very simple to do.
I'm just going to select it in this list of characteristics by double-clicking.
Now, down here at the bottom in the Code, I'm going to build an equation.
Now, the equation for average is basically diameter X plus diameter Y,
divided by two. Right.
So I'm going to go ahead and enter that in.
I'm going to select parentheses
with the keyboard and then double click on Diameter X,
hit the plus sign
and a space, and then double click on Diameter Y.
I'm going to close that with the parentheses
and then I'm going to add divided by two.
I'm going to finish the whole thing off with a semicolon.
Now, down at the bottom, I'm going to hit the Save button.
This will automatically check the equation that I've just written,
and if I've had any problems,
a dialog will appear and tell me what my problem is.
I'm satisfied with this.
I'm now going to copy this characteristic from my Part Library
into my Routine Library.
So I'm going to click on Average,
and then I'm going to click and drag it down to the Routine Library tab,
back up to my tree
and then drop it onto Average.
The characteristics automatically added to the average routine.
And at this point,
I can see that the DAQ Source has automatically been mapped to Calculator.
I'm going to go ahead and hit save
and I can click, Create Run.
So I'm back in real-time and I can see that
I have my original characteristics for diameter X and diameter Y.
But I do not have my characteristic for average, I need to add that.
So I'm going to go to the 2D View tab and click on Create.
I'm going to click and drag Average onto the screen.
Now I'm going to make it look the same as the others by using my Apply to All
and Tile function.
So Drew, as I measure diameter X
and then diameter Y, the average is automatically calculated.
That's pretty simple to do.
So aside from averaging are there other calculations that we can do as well.
Yeah, basically any mathematical formula that anybody normally do by hand
or in excel, we can create a derived characteristic to do that.
Very cool. Thank you again for your time.
