Patent ID: 6955284

Claim:
Device for positioning a tool ( 1 ) in relation to a workpiece ( 6 ), said device having: three drives ( 2 , 3 and 4 ), which enable positioning of the tool ( 1 ) relative to the workpiece ( 6 ) in at least two of three perpendicular spatial axes x, y and z; two cameras ( 10 , 11 ) positioned between the tool ( 1 ) and the workpiece ( 6 ), the first camera ( 10 ) essentially along a spatial axis (y) being positioned for taking an image of a first workpiece edge, and the second camera being positioned for taking an image with respect to spatial axis (y), and the second camera ( 11 ) being oriented perpendicularly with respect to a second surface of the workpiece; and a control unit operatively connected to said cameras and to said tool, whereby, based on the two images from said cameras ( 10 , 11 ), said control unit analyzes the position of the tool relative to the workpiece along the three cartesian spatial axes (x, y and z-axes) resulting in the issuance of control commands for the three drives ( 2 , 3 , 4 ) along the perpendicular spacial axes.
