Pushing Depth Definition

    Spottool v8.3

    I'm inputting gun sag values in my pressure table, and was hoping someone could give me a clear description as to what the pushing depth value is used for. Does it's value have to be greater than the gun sag value? Thanks in advance.

    As per my understanding

    Gun sag: an offset to compensate for fixed shank deformation
    Pushing depth: After moving shank touches the fixed shank and achieves set pressure, it further tries to push down. Maximum pushing depth can only be as much as your stroke limit is (usually 20mm).


    Hope this helps.

    If you want, running Autotune from the Utilities menu at 100% speed in Auto mode or T2, will put in the gun sag values for you. Maybe you have already done that.

    Pushing depth is the point during pressurization at which the servogun "gives up," stops pressing, and reports a fault of "Pressure Shortage"

    As an initial pushing depth (it may take some experimentation,) I would try Thickness (part layup thickness) + gun sag value + 2 mm.

    Once you get it just right, it can detect things like missing weld cap or missing nut.
    Good luck.
