    Default Broaching Haas 30y

    We just bought a broaching tool for the lathe. When we set the values in VPS the cycle starts cutting way inside the starting diameter and never goes deep enough.
    I know it has to accommodate where the edge of the cutter contacts the arc of the bore but it starts more then .25” away and with passes of only .0015” it takes forever.
    The broach is only .25” wide and the hole is 1” diameter.
    Any suggestions as to why?

    I am not familiar with this control specifically but when encountering problems like this on a conversational machine I find it's typically that the tool's dimensions aren't properly defined. The .25" wide cutter and the .25" away may be the clue you are looking for.
