Renishaw "Metal Condition"

[BBprecise]

So I'm trying to decipher a measuring routine a former employee created and the only thing hanging me up is the use of var# 146 Metal Condition. I have never used nor seen this used so I'm hoping someone here can explain what is recorded in that variable? None of the Renishaw literature I have explains what that variable is for.

 

Thanks.

Everything I have shows optional output. It is listed as Variation(Stock) if used in the Stock Allowance Cycle. All others it is used in list the same thing Metal Condition. You have to open up the macro and follow the logic of the macro to see what it does.

From 9823 3 Point Bore or Boss Measurement I see this math for the output.

#146=#143*#30/2(**METAL*CON)

Now we need to see what #143 and #30 are defining.

#143=#138-#7(**SIZE*ERROR)

That then used #138 -#7 for get a size error. #143 is also an optional out of Size error. Which leads me to think #138  defined size for the Probing routine is used. Whatever the difference is negative or positive is used minus what ever is defined in #7. #7 is part of the routine used across many different macro calls when probing. Best I can tell that exact value of error from what it should be and what it measures is what #146 is outputting. Easy test is run the routine you want and use a .1 difference between then routine and the feature measured. See if that value is that amount. Adjust +/-.02 and see if that output changes that value. That is the method to see what it does and then see how you can use it for your probing needs.

So I did a few tests on the only machine I had available and what I've determined is that on a single surface (9811) measure on the Z it always reports the same value and sign as #142 and #143. However on a 9814 bore/boss #146 reports as half of #143. If the bore is stock off #146 reports as a negative number. Looking around in 9814 the macro either sets #30 as a 1 or -1, depending on values in #7, #18 and #26. I didn't have a boss to measure but I would assume that a -#146 is stock off and a +#146 is stock on. I need to test if a bore measures small how #143 and #146 report as well. If #143 always reports as a + number I can see how #146 could be a better choice.

Thanks.

Excellent problem solving and information collecting to come up with the results.
