To measure a piston rod, the part is placed on prisms and the measurement is started. The sensor moves in a linear direction along the preset surface line at a speed of 100 mm/sec, meanwhile recording 1,024 individual measurement points. Roughness information is gathered over the whole functional area and can be used to monitor the finishing processes. Monitoring takes place directly next to the finishing machine.
Piston rods can be ground and finished in two different directions. One main benefit of the sensor’s design when measuring piston rods is its ability to detect isotropy attributes resulting from grinding directions on the surface, by rotating the sensor.
