Machinery Temperature Estimation



Development of a virtual sensor (DVS®) in order to provide nonlinear temperature compensation for inline measuring system, applied on high-speed machining for ballscrew production. This kind of compensation is needed to estimate the pitch and P.C.D. ballscrew measurements at ambient temperature. The required real-time measurement are temperature of the piece worked part (hot temperature), temperature of the piece cold part (ambient temperature) and measurement of the piece dimensions in hot temperature conditions.


The DVS mean estimation error is <1μm, against a measurement system resolution 0.1μm. This solution allows to have an improvement of the real-time optimization system for a systematic nonlinear temperature compensation software tool has been developed to be embedded in the machine measuring system.
