    Re: i j k errors

    N5020 G91 .....
    N5030 G3 X-0.36 I-.36 J0.

    With G91 active (N5020) the end point and the center point of your circle are identical (X == I). That will not work.

    I guess you have got an inclined bed lathe.
    With this type of machines the kinematic transformations (for example TRANSMIT) in reality is a concatenation of two transformation.

  3. Re: Any problem solvers? -> Need help with G02/G03 programmed as X Y I J

    If I understand correctly the two machines do have different controls i.e. only the new machine has got a sinumerik control.
    Though it will be rather impossible to compare parameter sets of both...
  4. Re: Any problem solvers? -> Need help with G02/G03 programmed as X Y I J

    You did not tell us which type of sinumerik your are using.
    If it is not a very old model you can try the following:
    If for example you have J17 in your NC-program replace it by J=AC(17) (and...

    Re: maximum feed rate - sinumerik 840D control

    I don't think that you can increase the max. feed rate of your machine by just changing a machine parameter. That rather would require more powerfull drives.
    Why do you think that the max velocity...

    Re: Apprentice Siemens user questions!

    G-codes are not specific for certain machines.

    Re: My circles are always too small. Why?

    Does the error depend on speed, that is does it get smaller with reduced feed rate?
    Keep in mind that with a normal closed loop control (without feed forward compensation) the radius of a circle...
  16. Re: Multi part fixture 60off with Siemens 840D controller

    I don_t thin that $=AA_IM[X] will be accepted by the controller. It should read
    $AA_IM[X].
    For the rotation you may write
    $P_UIFR[2,Z,RT]= < Your R-Value >
  17. Re: Multi part fixture 60off with Siemens 840D controller

    Using TRANS does not influence G54 i.e. TRANS is effective relative to the coordinate system defined by G54.
    So zero offsets and rotations of G54 stay active.
    Concerning your question whether TRANS...
  18. Re: Multi part fixture 60off with Siemens 840D controller

    If I understand correctly what you are trying to do it means that you want to concatenate G54 and G55. That's not possible because both frames can't be active at the same time.
    But you can...
