need help on horizontal

[left coast lefty]

We would like to machine around the 3 bosses and the port on a horizontal. There is a .062 max radius around the port where it hits the drive surface. We tried rotary 4 axis from the multiaxis menu but it only accepts ball endmills. We would like to use a .750 bull or something to that effect. Can anyone point us in the right direction?

 

Thanks in advance.

Try a swarf toolpath and constrain it to 4 Axis output.

5axmsurf Parallel cuts will work with a bull em. Keeping in mind your end mill needs to be ground with a flat bottom.

Here is a Curve 5 axis locked in the 4th....the distance increment and the curve follow method have been changed to .2 in the " cut pattern"

 

so that I could fit them on this page...max is 2 megs

 

They normally default to .05 and .005 respectively

 

The origin is the tool control as Ja.....errrr CNC guy mentioned above

 

 

 

HTH ...this is for referance only mind you

Thanks guys. Sorry, been away from the computer for a couple of days. We'll give these a shot.

OK, this just became hot.

 

Jack, how do I get the rest of the port without overcutting? Do I have to transform this outward with small increments? There must be a better way, but I'm totally clueless here.

If you click on the parameters page you will find linking/roughing directories etc that will alloy you to step this down with the endmill as well as side step and you can add a lead in/ lead out to this toolpath...If I add more to this toolpath above I cannot put it in on the page as it maxs out at 2 megs

 

The tool path presently uses the OD as the drive surface and the chain around it as a cutter comp guide.

 

When this has been roughed down you can either use smaller steps to get a finer finish on the side walls with this toolpath or use surface contour to get the side wall nicely cleaned up to the highest point on the OD from the front view

Thanks a lot Jack.
