The First Scan 150R non-contact, fully automatic precision measuring system is designed for cylindrical components. It can perform non-contact measurements with accuracy and speed and is easily networked to provide data to a variety of SPC formats, the company says.
The measuring system uses a telecentric backlight illuminator to produce a high-contrast silhouette of the workpiece to be inspected. The illuminator increases edge contrast and measurement accuracy designed specifically for gaging applications. The images are received by a high-resolution digital line scan camera that can take measurement data from the part at rates of more than 14,000 updates per sec. This data is collected by 8,160 sensitive pixels that can detect changes in the light pattern at sub-micron resolution. During the scanning process, a calibration cone, which is incorporated into the workpiece holder, provides the basis for all measurements to be automatically provided by the machine.
Once the part image is scanned, an unlimited number of measurement zones can be preset along with the corresponding dimensional specifications and control limits.
In-machine probing doesn’t reach the power of CMMs but can still be useful for pre- and mid-process control, as well as for “rough screening” of parts.
