Problem- 4th axis degrees of rotation.

[Wolford]

Hi guys, I have a slight problem with a part we make. Machine is a Makino a61, the part is a stator vane that is located in the middle of the B axis, tool 1/2 ball nose. Any who I program the part in a zig fashion, where the mill starts at the top of work piece and spirals down. The problem is before I can get to the bottom the control alarms out cause by b axis movements are greater than 99,999*. Speed and finish are critical. I can't use zig-zag because customer is very picky, not to mention it is a little slower. Is there a remedy in surfcam or?

Oh machine control is makino professional 5.

Thanks,

Wolf

Do you have a file or picture, so i can see alittle bit more of what's going on ?

I don't know your control but I know those parts

There should be some paramiters that let the axis roll back to zero (reset the axis)

[Wolford]

In my post there are B movement greater than the control can read. Be nice if surfcam would zero out every 360 degrees.

If you are using the MPost then search in postform.m which one you are using and modify the B register.


B ->3.>3 mod 360
or
B ->3.>3 mod 360 mult -1

It just add the mod 360 for the B register!

Then you could output 0.001 -->359.999 --> 0.001 and also postive way!

Maybe you also need to modify your parameter about the B axis in the controller.

If you are using SPost, you need to use SPost Configuration to modify your Uncx01.Pxx
