Need a little help with a 4 axis that is not posting out right.

Have a haas vf5 with a rotary axis. I have a trunion table that holds the part and needs to rotate to two specific sides 90* and 270*.

in mastercam i am using a contour 3d toolpath and was able to post out for the 90 degrees but when i try to post out for the 270 degrees it gives the following errors.

I have the axis control set to rotary axis positioning and the planes set to top/ back/ back. let me know if i need to post anything else.

The expert will get to this later.

Sounds good...

this is what i have tried so far.

Verified my machine defninition manager settings with a buddy. all look good
Reinstalled X6 thru mu3 update
deleted the operation and redid - same issue


A buddy took my file and was able to post it with the a values working but then tried to post the same thing again and he got the same error.

machining view cannot be achieved by rotating only 1 axis ( in relation to the WCS that you have used)

[Iggyg00]

Hello thank you for the info... was able to get it to work yesterday but didnt understand why. know i do thank you.

[cadcam]

for example using the default bottom plane or WCS rotates the part around the Y axis instead of the X axis so this can not be achieved with this machine setup.

[etech4u]

On the 4th axis you can not use the back plane as it relates to the top view. The way we get around it is to use dynamic plan to create a view that will roll in the right direction without needing to turn the view in a second direction.

[cadcam]

(On the 4th axis you can not use the back plane as it relates to the top view.)
Are you trying to say that it rotates around the Z axis instead of rotating around the X axis as needed.The Dynamic tools are great for this type of thing as they are interactive and easy to use. just did a Webinar yesterday on one use of programming are part with 4 side and 4 different ops using Dynmic WCS

Did you get this issue worked out?

[ttckcncuser]

im having trouble with the rotation of my 4th axis on the haas vf-2, during the program, when its machining on the x axis its going slower than dirt (cause you have to turn ur feed way down to keep from throwing alarms for exceeding max feed rate) but when its machining on the a axis its hauling ass and i cant figure out how to correct it or compensate for the problem and its getting close to crunch time on the part, need help fast. please and thanks

[txcncman]

Inverse time feed?

[cadcam]

As Txcncman stated you want to see G93 and G94 in code.
Can you share the Mastercam file and what post are you using. may be able help with this.

Hi, did you figure out this problem. I know it is a very old post. But if you still have this problem then i have a solution for it.
