Measurement of metal stampings
Metal stampings made from ground stainless steel are precisely measured in a fully automatic measurement system containing two optical optoCONTROL micrometers. These stampings are cylindrical in shape and are measured for precision in roundness, concentricity and diameter.
These optical micrometers form one focal point at two different positions and to measure roundness, a ray of light is passed through the two focal points. An encoder is used to provide high precision edge and diameter measurements by rotating the blanks. These rotations are performed thrice in this case to get the roundness measurement. The ODC2600 optical micrometer also simultaneously calculates measurements for concentricity and curvature. The measurement system is also immuned to ambient light due to the elecentric lens and optical filters installed in the system.
