Work-piece surface e.g. cylinder surface, measuring method for use in e.g. processing machine, involves filling gap between sensor and inner and outer surfaces in measuring area with liquid, which is transparent to measuring radiation

摘要

The method involves determining a surface structure of a cylindrically curved inner surface (601) or outer surface of a work-piece by an optical measuring sensor (610) attached to a probe body of a measuring probe. A gap between the sensor and the surfaces of the work-piece in a measuring area is filled with a liquid (631), which is transparent to measuring radiation. The measuring area is cleaned using a cleaning device (630) before or during measuring, where the surfaces of the work-piece are rinsed with the liquid during cleaning of the measuring area. An independent claim is also included for a measuring system for measuring a surface of a work-piece.
