  1. parts manual or part number

    David, may I purchase a copy of the parts manual from you? If not, can you give me a part number so I can try to get a part from South Bend?
    I called South Bend today. They said my lathe is too old....

    Re: Not reading some V5 CATIA files

    Thanks for the attention to this.
    Orchid just replied to me to tell me it should be fixed in the 2015 Beta that will be out in about a month.

    Not reading some V5 CATIA files

    Guys,
    I am a long time user of VX/ZW3D. I am not using the 2015 version. I need to translate some V5 CATIA files for a RFQ. I downloaded and am now using the trial version of the latest 2015 as of...

    Re: XY out of square!!!

    I would think about shimming the Y axis blocks for a while before doing it. I don't think it is the same as adjusting the Z axis guide.
    What you want to do is align the machine components with the...

    Re: XY out of square!!!

    How far out are each?
    I think a 6 inch machinst square would work very nicely for your machine.
    An ajustment of the Z blocks will not affect motion but will affect the tool axis squareness.

    Re: XY out of square!!!

    good point - I did assume the asker is competent to do the adjustments I suggested.
    On that vein

    Hyrum - how did you determine the machine guides are out of square?
    What do you have to determine...

    Re: XY out of square!!!

    underthetire - I will agree.
    About the only reason to worry about level is to get the coolant to drain in the correct direction. :)

    Re: XY out of square!!!

    Not sure why you would think this way.
    We have done this on our three Haas mills (VR11, VF10, VF6) and have been VERY pleased with the results.
    As far as I know, we have only done it once to each...

    Re: XY out of square!!!

    I think the answer is yes.

    Loosen the Y axis blocks under the saddle that runs on the Y axis guides. This will allow you to adjust the X axis so it is square with the Y axis.
    That machine looks...

    Re: XY out of square!!!

    Don't think of it as Y is out of square with X. Think of it as X is out of square with Y. The Y is not adjustable. You can do this without a technician. Follow the procedure outlined in the first...

    As previously noted - opinions are many.
    In my opinion NCL from NCCS is the ultimate CAM system. NCL will cut anything in any way you want. NCL is expensive. NCL has a long learning curve.

    You are correct to assume most 5 axis machines move point/vector to point/vector - one line at a time. Assuming the tool tip describes the programmed path is not correct. Some CAM system allow the...

    I must agree .010114 is too much.
    I must disagree .0004 is the correct amount.
    The correct calculation is in a post above.
    The correct calculation is approximately equal to my observe measurement.
