Forming contact detection function for machine tool etc. - determining stop positions or movement path due to external force by sensing changes in vibration

摘要

A movable part is vibrated by the supply of excitation, which is electronically or physically scanned, also the influence of their vibration parameters, e.g. amplitude and/or frequency or phase, by the contact of the moving part with a further part or stop. This is used for deriving a contact function, related to a direct contact of this part, or a contact of these parts across a third part. Pressure force determination is used on gripping, squeezing and clamping units. Linear and distance measurements are carried out with the coding of objects. Piece goods are counted using the scanning function, and can be used further for the noise damping of machines. USE/ADVANTAGE - Robots and manipulators esp. machine tools such as lathes and milling machines. Gives improved contact time point identification of tool removing material and coarse and fine adjustment.
