This post is dedicated to Grepper and we'll explain why in just a little bit. We're continuing to improve on our methods and apparatus in creating a homogenous roll. Our latest data set taken after the edge was rolled was better than we could have hoped for. We're going to have to repeat the test to see if we can duplicate our first results. We've taken to calling our efforts an "engineered roll" so please get used to our using that term.
We've developed a whole new way of rolling the edge in a repeatable and homogenous fashion hence our "engineered roll" terminology. We've need to tighten up our process so we will be refining our test fixture over the next couple of days. Then, hopefully, we'll post some sample results.
So on to Grepper. Mr. Grepper has taught us, repeatedly, in his posts about the importance of lighting when taking microscopic pictures. We thought that we would give you an example of what can be learned about edges if we all listen to Grepper's advice. Here's our initial picture of the edge that we just rolled:
It looks like something but what? We know that the edge is rolled because we can measure it. What does the roll look like?Here's what a little change in lighting can do. In this case we've simply altered the angle of the camera, thereby altering the angle that the light strikes the edge.
And here's another at just a slightly different angle:
Now we can see what we are dealing with and it looks just exactly as we imagined it should. The edge apex appears to be rolled at about a 30 or 40 degree angle. Thank you Grepper!
