Air Force called the Aero-Almen strip is the only way to assure safe operation and you will learn how to prepare, blast and read the intensity using this strip |
||
| 11 | Almen Gage
Practice and R&R Study - Staff - Electronics Inc . Wouldn't it be a shame to be doing an excellant job of shot peening or blast cleaning but not get credit for it? This can happen if your Almen gage practice consumes too much of your allowable peening intensity tolerance. You'll get a chance to practice using an old analog gage and new digital gage and compare the performance. Working in groups of three students each will measure ten Almen strips three times (total of 90 readings). The goal is to have as low of variation among readings as possible. |
||
| 12 | Almen
Saturation Software (Almcom) - Steven Baiker - Baiker AG Wouldn't it be nice to have a computor program print the Almen saturation curve, give you the intensity value, and warn you of inconsistent data? Well, it's available and in use in Europe. You'll see how hand generated graphs are subject to wide variations depending upon the skill of the operator and then see how the computor program can provide "the answer" automatically. |

The intensity of the peening media stream determines the size of the dimple. Coverage, or the percentage of the surface dimpled, is controlled by time and media flow rate. Learn how to measure intensity with the Almen strip and estimate coverage with 10x or 30x magnification. |
