    5 axis post-What should I expect?

    Our company purchased a 5 axis router which also has a rotary axis. The manufacturer (not AlphaCam) supplied the posts and it's been months and we're still working out bugs that make the machine unpredictable at times . Also, we aren't getting a good finish quality. I have experience with CNC lathes and routers, but this is my first experience with 5 axis, so I was hoping you guys could give me your thoughts.

    Is this a normal process for 5 axis or should we expect the posts to be bug free the first time? Also, how can we determine if the finish quality is an issue with the post?

    re: 5 axis post-What should I expect?

    I've found a lot of performance difference depends on if the inverse kinematics is done in the controller or if that is being done in CAM.

    Thanks burdickjp! What have you found is most desirable, if the IK is done in the CAM or the controller? (Ours is done in the controller)

    I prefer controller.

    What is your controller? What is your machine?

    I would rather not name the machine, but it's well built and heavy duty. The controller is Fanuc.

    I'm also wondering if we go to Alphacam for the post if it will be right the first time, or at least close, or is it just the nature of 5 axis to have a long process of working bugs out? .

    Normally if you have a Fanuc controller and all function are active in a machine (like command for 5 axis and plane transformation TCP G43.3/4, Plane change G68.2.. ) it is fast process with Fanuc. BUT do not know your machine specification and kinematics.

    My experience with 5 axis has all been with Siemens 840Ds. Issues I've seen have all been related to machine builders not following Siemens' documentation, standards, and having things set incorrectly in the controller.
