Systems And Methods For Machining Materials

(canceled)

A computer-readable medium comprising program code configured to cause a CNC machining apparatus to execute a method for machining a work piece along a curving tool path, comprising:

• code for controlling a relative translational movement between a tool table and the work piece along the curving tool path, comprising code for 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
• code for 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.

A work piece comprising:

• a feature scribed while varying an angle of rotation of a tool table with respect to the work piece to maintain a substantially constant angle between the tool table and a corresponding relative translational movement between the tool table and the work piece along a curving tool path.

A replication master for use in the production of an array of lenses comprising:

• a surface comprising a plurality of features thereon, wherein at least one of the plurality of features was scribed while varying an angle of rotation of a tool table with respect to the replication master to maintain a substantially constant angle between the tool table and a corresponding relative translational movement between the tool table and the replication master along a curving tool path.

A lens formed at least in part by application of a replication master comprising a feature for defining at least a portion of the optical element, wherein the feature was scribed while varying an angle of rotation of a tool table with respect to the replication master to maintain a substantially constant angle between the tool table and a corresponding relative translational movement between the tool table and the replication master along a curving tool path.
