Broaching a keyway with the Tormach

I have a 'standard' keyway broach setup (broach tools with collars and shims) and an arbor press. I know how to do this method.

Is there a CNC method I don't know about? Specifically, I am cutting a 3/32" into a .375 diameter hole in a wheel hub that is .5" deep (through the entire way).

Just wondering if a tool exists that I could do this with the CNC machine.

Never hurts to ask.
