5x Rotary Table Hint

[Jandr0]

Hi everyone,

Today i have a problem that my workpiece is just a little bigger than my table (outside my xy axis travel limit).

I know that the contour toolpath can be done with different C-angle in each wireframe section to avoid overtravel move.

But what i want to ask : is possible if i just make a single toolpath to solve this travel limit issue?

Here is the illustration to make it clear. Pink line is the axis limit.

Any solution would be really appreciated. Mcam attached.

Thanks in advance!

Try the axis control page - set rotation type to 3 axis, about Z, this is post dependent but will give some XY and C axis motion that may keep the path within the travel limits.

Mr Fish,

Can u please give me an example for the correct output gcode from my mcam file? Using the correct post

Trying to figure it out by myself to edit the post, because the actual move on machine is not correct.

I follow your method, and I think the problem is start from line 24.

Been tried to edit manually into correct order (g43.4 H... Z...;) but still output wrong move 

Should it be G43.4? or there is another option?

Been on mastercam seat for 5years now, been doing a little change in my postability post. But nearly give up in this case.

I'm so curious to figure out the correct output, so i can guess where is the part of my post to be fixed.

Don't give me a correct post, just give me a clue (correct gcode output) so i can learn to fixed it by myself. If you please.

Thankss

WHen i do it it is G43.4 otherwise it would have to be perfectly aligned to the center of rotation

Odd you have a Postability post and have not looked in the Machine Definition to control this? When you reached out to your dealer and they then contacted Postability who always provided world class service what was their answer?

You are tying to use a rotated plane to keep the part within the axis travels? I would look for using Rotary Axis Positioning in the Rotary Axis Control and see if that helps. Most Postability post have the G68.2 Logic hard coded for K on a Table-Table Machine. The other operation would be try using 3 Axis and using the Rotate around Z to get one toolpath to cut the whole OD, but spin the table. Problem might be do you have enough Y axis to allow that? If the part is too big for that then the way you are going about it will be the best way to machine a 500kg gorilla in a 5g cage.
