Profile measurement. (Instruments).The company's on-line 360 [degrees] profile measurement system is said to provide full profile measurement for extrusion, drawing and roll forming Roll-forming or Rollforming is a continuous bending operation in which a long strip of metal (typically coiled steel) is passed through consecutive sets of rolls, or stands processes in the rubber, plastics, and wire and cable industries. The Profile360 continuously measures the outside profile of the moving product and displays a pass/fail status. An optical comparator comparator Instrument for comparing something with a similar thing or with a standard measure, in particular to measure small displacements in mechanical devices. In astronomy, the blink comparator is used to examine photographic plates for signs of moving bodies. display shows the measured profile compared to a design template. Deviations from the template are displayed as error whiskers See metal whiskers. around the contour of the profile. A virtual caliper caliper Instrument that consists of two adjustable legs or jaws for measuring the dimensions of material parts. Spring calipers have an adjusting screw and nut; firm-joint calipers use friction at the joint to hold the legs unmoving. utility permits the user to set individual measurements and pass/fail limits for critical dimensions. The Profile360 provides analog outputs for process control. (Bytewise Measurement Systems, 1150 Brookstone Centre Pkwy., Columbus, GA 31904) Circle 73 on card |
