BROACH MAIN .MIN 

 ( USE A WORK OFFSET FOR BROACH TOOL BY IT SELF)
(YOU CAN ADJUST THE LOCATION IN X OR Y DEPENDING ON KEYWAY LOCATION)
(ALSO THE CODE IS WRITTEN FROM CENTER OF HOLE)
(THIS SAMPLE IS WRITTEN TO CUT KEY WAY AT 12 O ' CLOCK)
(THIS IS 2  FILES ONE IS MAIN PROGRAM ONE IS SUB PROGRAM)

(THE Q NUMBER  # MUST BE THE TOTAL DEPTH OF KEY WAY DIVIDED BY THE D.O.C.)
(IE... IF KEYWAY IS .130 DEEP AND D.O.C. IS .001 THEN = 130 )
(.130 / .001 = 130 )
( Q = TOTAL DEPTH / D.O.C. )
