Title:
METHOD FOR DETECTING SURFACE STATE OF WORK AND DEVICE FOR DETECTING SURFACE STATE
Document Type and Number:
WIPO Patent Application WO/2006/028295
Kind Code:
A1
Abstract:
A work (1) fixed to a movable table (22) is brought into a rotating state and cylindrical grinding is carried out while regulating the cutting amount of a grinding wheel (23) through a feed motor. During the cylindrical grinding, thermoelectromotive force is measured through a thermocouple (42) by pressing the thermocouple (42) against the rotation ground surface (1a) of the work (1) under a contact pressure. According to thermoelectromotive force data obtained through the measurement and the correlation between the thermoelectromotive force and the surface roughness predetermined for a known reference surface and prestored, the surface roughness data corresponding to the measured thermoelectromotive force is outputted and displayed on a display section. The in-process surface state of the work (1) can thereby be measured while performing machining, e.g. cylindrical grinding.
