ShadowGage is designed to measure features such as diameters, lengths and grooves on the contour of small precision parts, and then automatically separate the acceptable parts from the rejects. Single-camera systems can measure either the profile or top view of the parts, while two-camera systems can measure both views simultaneously.
According to the company, the machines can measure with an accuracy of ±0.0001" at a rate as fast as 7,200 parts/hr. Because the software recognizes the part’s orientation and then executes the appropriate measurements, parts can be loaded onto the machine manually or from a vibratory feeder, without regard to orientation.
Different instruments (and different operators) are prone to different errors.
Just because dial indicators have been around since the early 1900s, don't expect them to fade away with the last century. This tool's long-term popularity is well earned.
Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.
