4th rotary help please

[Sandybar]

I have a file uploaded ont he FTP site in the X4 folder called Crossheadnonose.mcx.

 

I'm have trouble attaching this toolpath. Keeps going into the checked surfaces and not sure why.

 

Thanks in advance.

I am not sure why that path is violating the checks, I only looked at it briefly. I have a lot better luck with the advanced multi-axis paths.

 

Do you have the advanced Multi-axis package?

[Sandybar]

Yes I do. What type of path would you recomend?

[cobra95kev]

I think the paralell to surface would work good and select the round surfaces as drive and the fillet surfaces as the single surface edge and leave the tool axis as normal to the round (drive)surfaces. Make sure you set it to do regions instead of lanes if you want to do both cutouts in one toolpath.

Thanks Cobra,

 

Worked out for me really good.

[cobra95kev]

Glad it worked!

Looks like the gap size was set too large in the original toolpath so it was trying to merge the drive surfaces throught the check surface. I decreased the gap size setting to 0.01" and it seems to avoid the check surface. Glad to hear the other method worked out too.

I've a little hic-up with this part. Machined one side just fine.

 

Trying to machine the other side, the clearance start's on the bottom of the part the feeds to above the part, or Top before machining. What type of tool plane do I need to do to get the right tool Path?

 

Thanks

Hmmm,

You might check your links page and see what those are set to if you are doing both sides in one toolpath. I never use clearance area I just use distance because all of our parts are left in airplane coordinates and clearance won't work for those.

 

Worst case you may have to break it up in to two toolpaths.

[Matt Sumner]

If you use the cylinder clearance area centered on the X axis it will probably work well for this part.

[Matt Sumner]

Hey Cobra95kev, good call on the Advanced Multi-Axis toolpath. You don't get those cool clearance options in the normal 5 axis stuff. That looks like it should run pretty sweet now.

[Sandybar]

Hey Cobra,

 

That is what it was, I had it set on clearance, put it on distance and worked. Where do the clearance numbers come from?

 

Thanks

[cobra95kev]

Matt,

Thanks for your tip earlier on the gap settings, I haven't messed with those much. I will be able to use that sometime.

 

Sandybar,

 

Those clearance values come from the system origin only. Kind of cheesey if you ask me because you can only use them if your model is setting right where it will be on the machine at the system top origin.

 

The distance option was actually a tip from a coworker so I must give him that credit. Glad I could pass it along. I have only been doing 5-axis for about 6 months.
