Abstract
A mounting arrangement 1 is provided in which clamping pairs comprising a clamping pad 2 and seating pads 3 are arranged about a mounting end of a component 4. Thus, the component 4 is appropriately presented to a machining device but the component 4 can slip relative to the pads 2, 3 in order to relieve residual stresses in the component due to initial forging processes. A damper 8 is provided in order to augment vibration control in association with the contact abutments between the pads 2, 3. In such circumstances accurate machining of a component 4 to a final profile 6 from an initial rough profile 5 can be achieved more efficiently without periodic release of the component 4 so that distortions are avoided in the final component as a result of retained residual stresses by previous clamping.
Claims12
A mounting arrangement for simultaneous machining of opposite faces of a component which may retain residual stresses, the arrangement comprising multiple point contact abutment clamping in use of a component, the arrangement characterised in that only three clamp pairs are provided to enable residual stress relief in use as the component is machined and incorporating a damper to augment vibration control otherwise diminished by the reduced contact clamping provided by only minimal contact abutments.
A method of simultaneously machining opposite faces of a component which may retain residual stresses, the method comprising clamping the component with multiple point abutment contacts and thereafter machining the component, the method characterised in that the component is only clamped by three clamp pairs and a vibration damper is applied to the component in order to augment vibration control otherwise diminished by reduced contact abutments.
