ABSTRACT:
A method for machining a blank includes machining a first pocket in the blank having a first sidewall, machining a second pocket in the blank, machining a groove within material located between the first and second pockets to expose a second sidewall opposite the first sidewall, machining the first and second sidewalls, and alternately repeating machining the grove and the sidewalls to step mill the groove deeper in the blank and form a third pocket along which the second sidewall extends.
