    Question can some one show me what a facing program looks like for a Hass Lathe.

    iam jujst starting out on one and if i can get any help its appreciated.

    also a turning program too .. what it would look like.

    Any stock size is fine ,, i want to see how to do it in a canned cycle

    Try going to

    http://www.haascnc.com/training/Misc...20on%20Web.pdf

    and download the free program generator. It allows you to quickly generate the canned cycles and the code to turn the part.

    Let us know if you need more help.

    Haas OR Hass lathe program?

    Are you programming a Haas machine or a Hass machine?, you should be as specific as possible, as there may be subtle differences between these machines, and the NC code may not work properly.

    here's the thing. I am telling you right now I don't claim to be an expert in long hand programming however I am about to receive my A.A.S. degree in machining tech and my emphasis is in CNC programming and operating. From personal experience I have found as a newbie in the CNC world it is far easier to program a facing cut long hand than it is to do in a canned cycle, only because, how many passes do you need to make for a facing operation? one, two usually...I.E.
    ( PREPARATORY COMMANDS GO HERE)
    G00 X1.5 Z-.010
    G01 X-.005 ( FIRST PASS)
    G00 Z.1
    X1.5
    Z-.020
    G01 X-.005 (SECOND PASS)



    And so on and so on. this is just for me an easier way of building and reading a program. because at my place of work and at school we do not have issues with information storage.

    I hope this info helps you, and I did not miss the point. thanks, joe

    try CNCsimulator. I think the web address is www.CNCsimulator.com it has a basic simulation program you can use to do basic verification programming. howeeer if you are serious about verifying your stuff you can buy cimco edit5 with the lathe package thats what we use at work and at school

    As it says at the top this program faces and chamfers the end of a piece of stock. If you copy this and load it into a Haas lathe you can watch in in Graphics.

    i guess at this point I still believe that z would be at the end of the part and negitive is cutting into the part I guess I'm not sure why this program is cutting at z-15.and dthe x is usualy programed off the center or the diameter so that seema ok. unless you mean that your g54 is setup off machine zero and then I think I would understsnd but then you would have to calculste that distance in your program. I guess to summ it all up I may not haver the experience that others may have. I can say that I have run a haas and fanuc controlers. please dont ask me to identify the model numbers. thanks joe please excuse the spelling it is now time to do honey doos

    You are referring to the G53 X-2. Z-15.0 line.

    G53 is machine coordinates so in fact this move takes the tool 15" from machine home on the Z and 2" away on the X.

    This program was written for a Haas TL2 and I use the G53 command instead of G28; G28 would take the machine all the way home which is 40 inches away from the chuck.

    The actual cutting moves start at line N7.

    The tool offsets are to the finished end of the part which is why line N8 has the tool positioned at Z0.15 just before the G72 canned cycle.

    The G72 faces the part down to Z0.0.

    Most times you would not need to take off this much material when facing.

    bobrob,
    The link appears to have changed. Try this one "ftp://haascnc.net/Training/" then download the folder QC.
    Rgds,
