Abstract
An adaptive precision chuck for a precision/ultraprecision machining system is described. The chuck (200) defining a mount for receiving a workpiece (300) wherein, when in use, the centre of the mount is configured to be substantially concentric with an axis of rotation (214) of the machining system, the chuck (200) further including jaws (201) about the mount and a plurality of compliant flexures (203-206) configured, upon application of rotational forces by the machining system to the chuck about the axis of rotation (214), to engage the jaws (210) upon a workpiece (300) in the mount.

An adaptive precision chuck for a precision machining system, the chuck defining a mount for receiving a workpiece wherein, when in use the center of the mount is configured to be substantially concentric with an axis of rotation of the machining system, the chuck further including jaws about the mount and a plurality of compliant flexures configured, upon application of rotational forces by the machining system to the chuck about the axis of rotation, to engage the jaws upon a workpiece in the mount,
- further wherein the chuck is mountable via mounting means to the machining system and the chuck includes third flexures associated with the mounting means, the mounted position of the chuck on the machining system being adjustable via one or more forces applied to the third flexures.
A precision machining system, including an adaptive precision chuck, the chuck defining a mount for receiving a workpiece wherein, when in use the center of the mount is configured to be substantially concentric with an axis of rotation of the machining system, the chuck further including jaws about the mount and a plurality of compliant flexures configured, upon application of rotational forces by the machining system to the chuck about the axis of rotation, to engage the jaws upon a workpiece in the mount, the adaptive precision chuck being configured to receive and retain a workpiece for machining by the machining system, the precision machining system further including a vacuum chuck, the adaptive precision chuck being mounted to the machining system by the vacuum chuck, the mounting to the machining system being adjustable via the flexures.
