Method of machining a workpiece into a desired patient specific object

A method of machining a workpiece into a desired patient-specific object having a first patient-specific surface and a second patient-specific surface opposite the first patient-specific surface, the method comprising:

• receiving a digital object representation representative of the desired patient-specific object;
• machining, in accordance with the received digital object representation, the workpiece into a partially machined object, the partially machined object having a first object surface replicating the first patient-specific surface and a second object surface opposite the first surface;
• securing the partially machined object to a support member, the support member having a support surface shaped using patient-specific modeling and configured to matingly engage at least a portion of the first object surface for exposing the second object surface;
• and
• machining, in accordance with the received digital object representation, the exposed second object surface to replicate the second patient-specific surface.
