I am trying to figure out how to read the chart in our standard practice manual. We are glass bead peening a part per the manual, which instructs:
Use Glass Bead Size 6 ( CP2238 ) or Glass Bead Size 5 ( CP2219 ) at an Almen intensity of F15N. Since I don't know how to past a picture in my message, it will be hard to explain the chart. I can try e-mailing it to you. On the left hand side of the chart shows "N Intensity" with two columns labeled "Inches" and "Afnor". The x-axis is labeled "Diameter of Glass Beads". My question is what is on the chart itself which has vertical lines with corresponding glass bead sizes.
My dilemna is that I am showing that with a F15N, the intensity should be 0.010"-0.014"N, but how do I double check this?
