4-axis wire cut point

[LansB]

Hello,

 

I am trying to chain a 4-axis wire contour but keep running into a couple snags.

 

The first problem I seem to have is that it won't let me select a cut point and it runs the wire back through the center of the part to the thread point. When I chain it I am selecting the thread point then the lower contour then the thread point again then the upper contour and it works. If I try to add the cut point into the program it says I can have no more than two contours???

 

The second problem I am having is that it allows the toolpath to run when 4-axis taper is selected but when I change it to direct 4-axis is says unequal number of entities. I have analyzed both contours and each one contains 241 entities???

 

Any help would be greatly appreciated.

 

Thanx,

Lans

"When I chain it I am selecting the thread point then the lower contour then the thread point again then the upper contour and it works."

 

That's the problem. You do not want to select two Thread Pts.

 

Order should be ->

 

Thread Point

Lower Chain

Upper Chain

Cut Point

 

The chaining order below is also acceptable, but I always suggest the method above - as it make "more" sense (Thread, Burn profile, Cut) ->

 

Thread Point

Lower Chain

Cut Point

Upper Chain

i use the lower one

emailing it on the way Del! Thank you!

 

Roger, I will try that out. Thanks also!

lans, i havnt gotten it yet.as far as the direct 4 axis goes.if you have splines you cnat do direct 4 axis only taper 4 axis.

[Guest]

ive got it. the first thing i see is that you are not using any sync.sync it by entity.are you only doing half of it at a time lans

[LansB]

Yes, half of it at a time. What you see is the first half. After that I will have to rotate it and do the second.

 

The break point is where you see the extended contours across from each other.

lans,another thing i see is that the entities are not trimmed as far as the top contour that iam working on

[LansB]

I re-chained the contours in the order specified:

 

thread

lower

upper

cut

 

I also selected sync byt entity and it looks 100% better. It still will not let me do direct taper though. "wire compensation not successful"

lans i am sending it bac to you.take a look at my parameters and see what you think.i moved your z to where i would do it for me personally. it looks good. i put the thread and cut point just guessing.

[Guest]

i went back and trimmed all of your top geometry

[LansB]

Thanks Del.

 

For some reason it is cutting the taper smaller at the top even though the geometry is reverse of that.

 

is this a parameter in my machine that differs from yours?

[Guest]

that is weird. i see that now.

[LansB]

Thanks a ton for your help!

 

I think I have it figured out now anyways. I used the suggestions you gave me and it looks to be good.

 

I'll let you guys know when we run it next week.

 

Thank you very much!

lans i have no idea why it is reversing the direction of taper. i have never seen that before.might want to send it to roger martin and have him look at it.

[Guest]

lans, you have new mail. it does right now.
