Abstract
Embodiments of systems, methods, and computer-readable media for machining materials are disclosed. For example, one embodiment of the present invention includes a method for machining a feature on a work piece (100) along a curving tool path having the steps of controlling a relative translational movement between a tool table and the work piece (100) along the curving tool path and controlling a corresponding angle of rotation of the tool table with respect to the work piece (100) to maintain a substantially constant angle between the tool table and the corresponding relative translational movement between the tool table and the work piece (100) along the curving tool path. In another embodiment, a computer-readable media includes code for a carrying out such a method.

A method for machining a feature on a work piece along a curving tool path, comprising:
- controlling a relative translational movement between a tool table and the work piece along the curving tool path, comprising controlling a dynamic feed rate of the tool table along the curving tool path to substantially maintain a target centripetal acceleration of the tool table with respect to the work piece;
- controlling a corresponding angle of rotation of the tool table with respect to the work piece to maintain a substantially constant angle between the tool table and the corresponding relative translational movement between the tool table and the work piece along the curving tool path;
- and
- determining the dynamic feed rate of the tool table at a plurality of positions along the curving tool path based on a set of coordinates defining the plurality of positions along the curving tool path.
A method for machining a feature on a work piece along a curving tool path, comprising:
- controlling a relative translational movement between a tool table and the work piece along the curving tool path, comprising controlling a dynamic feed rate of the tool table along the curving tool path to substantially maintain a target centripetal acceleration of the tool table with respect to the work piece;
- and
- controlling a corresponding angle of rotation of the tool table with respect to the work piece to maintain a substantially constant angle between the tool table and the corresponding relative translational movement between the tool table and the work piece along the curving tool path,
- wherein the curving tool path is substantially axisymmetric about a first localized coordinate axis on the work piece, and
- wherein the feature comprises a lens feature and the curving tool path further comprises a substantially spiral tool path beginning at the outside edge of the lens feature, following the substantially spiral path with a decreasing radius, and ending at the center of the first localized coordinate axis.
