<p>The invention provides work piece support apparatus for supporting resilient sheet material (2) during a machining operation, eg, routing, in which the support apparatus includes hydrostatic clamping means comprising perforated support pads (24L,24R) positioned each side of the resilient material and connected to a fluid supply. By this arrangement a fluid layer under relatively high pressure is interposed between each pad and the adjacent region of sheet material which is thus fluid pressure supported in the immediate vicinity of the routing tool (3) throughout the machining process. The invention beneficially provides a routing machine including the work piece support apparatus in which the work piece is positioned in a generally vertical plane and the routing tool is mounted about a generally horizontal axis (4).</p> |
