Swarfing toolpath problem

[Guest]

Would someone mind taking a look at a file for me.

 

Giving me headaches this morning.

 

It's swarfing toolpath run in 4 axis, which I've done before but I cannot get a good path this.

 

Might someone tell me what I am missing?

Huh? Looks like it should work to me. But it don't. Thanks John, now my head hurts too.

That's not me, that was those bottles of Vodka from last night.

I would recreate my geometry for the chians or use a different toolpath. You can use Swarf but you will need to use the SYNC method maybe points will work the best here. Create an equal number of points on the top and bottom chains. This will force the tool to SYNC along those points almost like Toolaxis control lines if you were using Curve5ax my favortie toolpath for something like this part.

 

Look at your file with CRAZYSPIN added to it see if that works for you. I would use a smaller endmill as well and needed to set 4th axis to Z axis.

Use SYNC Mode= By Entity

Output format 4-Axis = Z-Axis

SYNC Mode and it doesn't appear to like your WCS. i translated the part so i could use top view as the WCS and set the SYNC to Entity like Qmp said and it seemed to work.

Ron, Thanks I'll take a look at that in a bit.

 

Qmp, thanks for the suggestion.

 

I just changed my rotation from X axis to Z axis and the path looks better. I am confused as to why. I am rotating this part around the X axis of my machine.

 

Might this difference be because of the created WCS and the toolpath needing to see the actual coordinate system and not the created one?

QMP is right. it work if u sync by entity amd select 4-axis to z axis. but it would rgh that by regular pocket and stay away from the wall by 1/2 the dia of the rgh tool and use swarf to finish it. using multi path on swarf is not recommendeted.

One other thing I would do is change the lead in lead out as well. On a 4th axis with this type of lead in and lead out you will create alot of extra code that may not befit the cut. Keep the arc but maybe do away with the height unless it is really needed.

From WCS = top view your GEO parallele to Z-axis

that why you have to chose Z-axis

 

If you rotate the part parallele to X-Axis, you chose X-Axis ....

[Guest]

OK, I flipped my file all around. Made my part lie on the x axis origin, created new WCS's to work on for the ends and used the standard TOP WCS for the swarf path and it worked fine.

 

Thanks all for your help and suggestions

man they seem to be chewing up your part, but if you get correct code and learn something at the same time thats a win win in my book.
