Method and device for precise contact free measurement of loading on a rotating spindle for machine tool monitoring uses a distance sensor and measures and records unevenness with the tool operating in an unloaded state

摘要

Method and device for monitoring rotating tools (1) using a distance sensor (2) for measuring changes in the axle or rotating part's position when under load. The first stage of the method consists of producing a signal curve for the tool with no load applied. When tool rotation is then measured with a load applied the effect of any inherent roughness or out of balance effects can be compensated, so that any change of position is due entirely to loading of the tool.
