Systems, methods, and computer-readable media are provided for machining a feature on a work piece along a curving tool path including a spiral pattern with continuously varying radius. In particular, the feature is scribed by a tool while varying an angle of rotation of a cutting surface of the tool with respect to the work piece to maintain a substantially constant angle between the cutting surface and a corresponding relative translational movement between the cutting surface and the work piece along the spiral pattern. A dynamic feed rate of the tool also is varied continuously with respect to the work piece based on the continuously varying radius of the at least one spiral pattern to substantially maintain a target centripetal acceleration of the tool with respect to the work piece.

A method of milling a piece of raw steel stock comprising: presenting a piece of raw steel stock having a first surface and a second surface having a perimeter; presenting a magnetic chuck with a top surface configured to support the piece of raw steel stock for milling with magnetic capabilities; arranging a minimum of four solid pole extensions on the top surface to support the second surface of the piece of raw steel stock for milling of the first surface thereof such that the solid pole extensions will be relatively evenly distributed beneath the perimeter of the second surface; arranging multiple mobile pole extensions on the top surface to further support the second surface; placing the second surface onto the multiple mobile pole extensions and the solid pole extensions; activating the magnetic capabilities of the magnetic chuck; and milling the first surface to a desired flatness.
