5axis spiral help

[Bruce Caulley]

G'day all,

I have uploaded a file called bruce_swarf_spiral.mc9 under mc9 files on the ftp. When viewed from the front, the tool is not staying parallel to the wall when ramping down. I have tried different methods of tool axis control as well as tilt angles, but none seen to have any affect. Am I missing something simple???

 

The operation is part of a trial to test out our Mazak Vortex and new CMM, as well as giving me a chance to use a few of the more "funky" toolpaths available in MC. The job will be on the machine some time tommorow and I would really like to see this toolpath work. 9.1 maintenance

 

Any advice greatly appreciated.

Bruce, I ain't the best 5-ax man but you problem tripped me out. I couldn't figure the problem but check bruce_swarf_spiral_2.mc9 on the ftp. I am a big fan or curve 5axis. I just saved your backplot as geometery on level 50 then applied a curve 5ax toolpath. The angles look good now.

You're basically trying to Swarf cut with a Flowline toolplane, which is more tip cutting than swarf cutting in general. You could try axis control normal to the surface with a -90deg side tilt, or just use your point control, but use an Axis Limit, Z Axis, min and max at 20deg, Modify tool direction.

Thanks travis and Dave. I will try these as soon as I get to work today.

 

Some good advice as normal.

That worked Dave. Funny what you miss when you have a late night, I actually thought I tried -90 tilt.

 

Thanks for the time fellas.

Next problem. When the machine is retracting from an angled face, it is not moving in the tool axis. i.e GOUGE. I thought that this was only on the 5 axis parts but then it happened on the drills also. On the drills it looks like the XY movement and the Z movement on the next line should be on the same line together.

 

On the 5 axis paths it is the line with the 5axis substitute rapid feedrate on it.

 

If anyone can think of a fix from the scant info here I would be greatful. I will try a few things when I get in tomorrow and see if I can't provide a bit more info.

My fault. All fixed.
