Abstract
A cutting assembly and an apparatus for self-aligned chamfering of a workpiece are disclosed. The chamfering apparatus includes a mechanism for releasably securing the workpiece in preparation for a chamfering thereof, a cutting assembly, and a mechanism for moving the cutting assembly proximate the securing mechanism between a first position and a second position, wherein the cutting assembly traverses along an edge portion of the workpiece to be chamfered. The cutting assembly includes (i) a guide member having a guide surface; (ii) a blade member mechanically coupled with respect to the guide surface for establishing a desired cutting depth; (iii) a mechanism for applying a resilient tensioning force to the guide member, the resilient tensioning means applying a first tensioning force when the guide member is in a non-chamfer engaging position and applying a second tensioning force when the guide member is in a chamfer engaging position, the chamfer engaging position corresponding to a position of the guide member when the guide surface engages the portion of the workpiece to be chamfered; and (iv) a mechanism for locking the guide member to maintain the chamfer engaging positio…
