One CMM sensor measures roughness & waviness.
The Zeiss Rotos from Carl Zeiss Industrial Metrology, Maple Grove, Minn., is a new roughness sensor that enables standards-compliant inspection of roughness and waviness on a single coordinate measuring machine (CMM). The unit is intended for users that inspect size, position, or form on a CMM and who also need to measure roughness and waviness on the same workpiece. According to Zeiss, it is no longer necessary to transfer to a surface measuring instrument. All features of a technical drawing thus can be fully captured with one CMM and displayed in one record. A range of measuring positions can be reached without rechecking and a fully automatic run is possible without the operator influencing the surface measurement.
Instead of clamping the workpiece on a contact-stylus instrument, Zeiss Rotos is used via the stylus-changer interface on the probe of the CMM, under full CNC control. This takes just a few seconds compared with the previous several minutes. Measurement data from the unit is transmitted via Bluetooth to the analysis computer. The data is then imported into Zeiss Calypso software via a machine driver and can be exported with other measurement data in a common record. (800) 327-9735 * zeiss.com
