Cuurent support for Right Angle Heads

What is the current support for programming right angle heads?

It could theoretically be done. But would we would need to know a lot more about its capabilities. You would most likely also need to be running full InventorHSM to do the indexing type moves.

Hi Joe,

If you use 0 and 90 degrees it could be mostly a postprocessor thing. I worked with an old Maho machine with Heidenhain control, and we added a post configuration option "use horizontal yes/no". On this machine the coordinate system changed from tool pointing in Z directing to tool pointing in Y direction on tilting the head. If your machine is the same, it needs to be done in the post.

We´ll a solution to use angular heads in Inventor HSM now is to do it in the post indeed. But this would become quite tricky when your machine has more then 3-axis. Also the Maho machine everything thing stays the same it's just the axis switch that Achim made in the Maho post. But when you are able to turn the head by the program this isn't possible since it's not just axes being swapped.
So I understand it won't be a high priority but maybe put it on the list so it could be simulated correctly as well.(Very very hard I know)

eeek! We are at the beginning potential usage.

Thanks for the response

My concern would be if the machine has a straight 3 axis control. If you’re working at 90° quadrants you “could” just swap the axis so you would be drilling in the X axis instead of the Z for an example. But when you get to the odd angles it can get quite complicated depending on the control. And if the head also has a Z tilt it would be even worse. That’s why I said it could theoretically be done but there is a lot more that needs to be known before I could say yes or no.

I have a post for this but never tested it. The issues are the tool length offset (from the gage line at the main spindle to the center of the tool) and the X or Y offset the distance from the main spindle axis to the tool tip. This value could be in X or Y + or -. Another issue is the spindle rotation direction of the 90 degree head. Probably runs reverse of the main spindle direction. This depends on the head.

See some info here http://camforum.autodesk.com/index.php?topic=164.msg752#msg752

I was quoting a job for this function. But the job never happened. I think we were going to use a macro variable for the tool orientation and the length from the main spindle to the tool tip. If this is going to be a reality, then the tool needs to be defined within the tool file 2.0 so that real machine simulation can happen.

Don't know if this helps, but it might be a start.

Hey @JoeBarnes4076 did you ever get anywhere with doing this?
