    Most of these parameters control efficiency. For example, the machining center chip-breaking peck drilling cycle (G73) has a parameter that controls retract amount between pecks. The larger this value, the more time it will take to machine a hole. In similar fashion, the deep-hole pecking cycle has a parameter that controls the clearance amount between pecks. Also, the turning
