Hello,
Many of our older product lines use straightness and roundness to control cylindrical features. Moving forward, we will be using cylindricity so that taper is also controlled. Is there an efficient way to convert straightness and roundness dimensions into cylindricity? Thanks.
@drawoh, for the record I would prefer cylindricity. The way it was described to me, our suppliers have been using straightness and circularity for so long it was "easier" to not change it and just add the KCCs to it to the current spec. I don't fully understand the reasoning, but I like to...
Hello,
The company's global team for a product family is calling out cylindricity as a KCC moving forward. Due to supplier relations/history on these products for our specific plant, we will be using straightness and circularity as KCCs. What are everyone's thoughts on this? Are we losing any...
Hello,
I am doing an MSA on our measurement process for flatness. We are using an inverted gauge installed under a granite block. The issue I have is that when measuring flatness, no two operators are going to be hitting the exact same points. I can create a fixture to ensure they are hitting...
Thank you for each of your replies.
CheckerHater, would it be correct in saying the entire surface flatness is the "Global Flatness" and flatness per unit of area is the "Local Flatness"? Is there a better way to measure the local flatness of a part than using an inverted gauge under a granite...
Hello Everyone,
I recently started at a new plant and we seem to be having flatness issues with two of our parts. The two parts have a flatness spec that reads .0002/IN, while our other products are all .0005 for the entire surface. The quality department says the .0002/IN can just be...
