Reverse engineering let engineers design an adapter so the old mount could accept the new motor.įor example, a blade on the impeller of an air compressor broke off after years of service.īut the compressor manufacturer asked for eight months to make a new one. The image can be enhanced for end use by engineering programs that deal with surfacing, stress analysis, human factors, ergonomics, plant layout, or product flow.įor instance, engineers in a steel mill needed to replace an aging 7,500-hp motor. Then transcribe dimensions into a digital or CADcompatible format as an image of dots, streaming lines, or wire frames. The key is measuring with sufficient accuracy to capture the degree of detail necessary for a faithful reproduction. Zone 6 would be scanned with a 3D hand-scan method to completely capture the fillet radius. Zones 1 to 5 and 7 would be scanned using a parallel-plane technique. Laser-tracking devices such as this one have a range of 230 ft with up to 0.001-in. In this case, a laser tracker, temporarily in the center of the production line, can measure to any spot on the machine. Reverse Engineering Ex4 Using Software Portable CMM Is.
