Abstract: A clamping arrangement has a clamping device is fastened fastenable on a clamping base, and a clamping element able to be tightened thereon. The clamping device has a clamping module with clamping members that can be fixed by a fixing element on the clamping base, wherein the fixing element is configured such that the clamping module is fixed in the X-Y plane in a floating manner. The clamping module is displaceable in the fixed state of the fixing element with respect to the fixing element in the X-Y plane, but is non-displaceable in the Z-direction. The fixing element is provided with Z-support surfaces for the clamping element. The clamping arrangement is particularly suitable for a large clamping system, so that thermally caused dimension changes of the workpiece carrier with respect to the clamping base can be equalized with repeatable accuracy, without the clamping system being over-constrained geometrically/mechanically in the X-Y plane.
