<p>Device and method for compensating a non plastic deformation of a first machine element (2) and possible supporting means (7), said first machine element (2) at least comprising machining means (1) and being fixed to a second machine element (3) in linear operation at least comprising one feed slide (4) and one linear motor (5). The device is characterised in, that said feed slide (4) and linear motor (5) are arranged with position feed-back in a position closed loop configuration (6); said deformation is arranged to be substantially compensated by a linear movement of said second machine element (3) effected by said linear motor (5); and the extent of said linear movement being arranged to be based on current alterations in the winding of said linear motor (5), which are caused by forces exerted on said linear motor (5), said forces originating from the deformation of said first machine element (2) and said possible supporting means (7). <IMAGE></p> |
