Move in ARC

[johnr4mbo]

Hi,

 

I'm trying to drill 9 holes in a diameter of 319.5mm.

I use a normal drill operation.

But i want it to move from hole to hole in an arc movement since there is still material in the middle which is higher , atm it's doing that in a straight line.

now i need to retract my tool 100mm everything time it travels from hole to hole.

 I hope you guys understand my poor english. xD

 

Thanks,

Rick

Use the clearance height to retract and uncheck the box under it. It will not go in an arc unless you program it as some sort of funky contour instead of a drill path and jerk with the toolpath editor.

You will probably  have to do it with each hole as individual ops and add a contour move at high feed rate between each one.  Otherwise you will have to create a macro that would do it for you.

If you have multiaxis mc license, you might be able to use that to drive different behavior, but I doubt it will be as effective or straighforward.

I am assuming this is on a fanuc control?

It would take a combination of single hole drill locations and 3D contours and a bit of editing to get it as I understand the users wants it

Thanks for replying all.

it's fanuc yes.

I hoped there would be an Simple option for it that i missed.

I'll try to mess around with some stuff.

You could also use the Sort option to control the movement between holes

Would doubling the number of drill points and alternate between G80 and G81 each successive hole work? (are you trying to avoid a hub diameter).

I didn't try but it could work: If you have multiaxis you could try one drill toolpath per hole then multiaxis linking toolpath.

Drilling with Safety Zone of a cylinder should do it with no problem. Here is the link to an example I put together to show anyone.

Have to use Solid holes to achieve this toolpath. Arcs, lines planes or points and it will not work.

Welp!  Ummm sir Haas machines would not have a fanuc control.  They have a Haas control!  Close for most, but definitely not the same thing.

ron, that would be fine drilling the outside of a cylinder.  But I believe the application he is referring to is drilling a bolt circle axial to the cylinder.  Think avoiding the center of a wheel hub while drilling from the front side.

Then yes that is incorrect and would have to use one of the suggestions noted above. Why it has to travel in arc I assume to to avoid the center piece. I have done what others have suggested and drilling one hole then use 2D with no comp to follow the arc from one hole to the next.

Couldn't this be done by drilling a single hole and creating a Transform-rotate operation?

I don't think it will create the arc move around the center boss like they want. I have to assume the tool is long and to bring it up and over might over travel the machine. I have done things like this over the years and like others mentioned it just some work.
