K Diagram only for mean value diagrams

[[Ow...]]

Would somebody care to elaborate on this and also explain how the diagram alignments work on the K-charts?

I looked in the manual to no avail, and while it seems fairly intuitive, I'm looking for some examples with explanations. 

Hoping somebody has some documentation on them.

TIA

Owen,

 

 Howdy, sure, these are mainly to tell Gear Pro how to align the K-Tolerance Band to the actual data, there are a few ways. By default with a K-Chart I think the general rule of thumb is the 'highest point of the trace/measurement' typically aligns to the top of the tolerance band. What is shown as upper tolerance option above. There is also the option to align the trace/measurement data of the lowest point which will then 'become' the lower tolerance band alignment.

Reference Line is to any arbitrary 0 line to attempt to center the trace I presume.

Zero point I think is to start the band where the trace starts at zero it appears.

You can also restrict the alignment range allowed so as it looks for a hi point or low point of trace, you can restrict the area it searches for, this is typically reduced to the main profile area around the center /PD allowing for some end relief etc.

In most cases unless otherwise specified - upper tolerance should be fine, if unsure consult your Engineering Dept.

Good luck !
