SENSOR, FRICTIONAL FORCE MEASURING METHOD, PRESSURE MEASURING METHOD, AND FRICTIONAL FORCE/PRESSURE SIMULTANEOUS MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a new sensor capable of accurately measuring frictional force and pressure acting on a tool surface or the like, and a measuring method of the frictional force and pressure.;SOLUTION: Substantially parallel two beams 3 and 4 are disposed to connect to a thin part 1A of a tool 1, lower ends of these two beams 3 and 4 are interconnected through a thin plate 5, a plurality of strain gauges 6-1 to 6-4 are disposed near joints of the thin plate 5 with two beams 3 and 4, and a sensor 10 is constituted integrated with the tool 1. Then, the frictional force and pressure applied to the thin part 1A are measured by detecting strain of the thin plate 5 via the beams 3 and 4 with the strain gauges 6-1 to 6-4 and taking difference or sum.;COPYRIGHT: (C)2004,JPO
