<p>A fixture (10) for supporting a workpiece (18) during a machining operation. The fixture comprising a base (12) provided with a channel (14) for receiving part (16) of the workpiece (18), the channel having a first wall (20) facing an opposing second wall (22). An inflatable diaphragm (24) is located on the first wall (20), and configured to engage with an engagement surface (36) on the workpiece and bias the workpiece against the second wall. The diaphragm comprises a deformable portion (26) spaced apart from the first wall of the channel, the deformable portion having ends (28,30) which provide a seal with the first wall to define a chamber (32) enclosed by the first wall and diaphragm.</p> |
