Re-Machining Quirk

[Mic6]

So I machined out a .5 wide slot with a .25 em. Now I'm trying to go back and pick out the corners with re-machining and a .0935 em. This was working just fine yesterday even with my clearance at 40% I could see it blending in verify. Now today even with these settings

 

Or even at 100% I cant get rid of the little bits of stock. I left zero stock when I finished the slot. It seems like no matter where the clearance is set, it wont cut it.

 

Leaving 0 stock in the remachining, the chamfer shows heavy, and the slot wall shows little chamfer. I opened yesterdays part just like this, and now it's doin the same thing as well.

 

Any ideas?

What about if you backplot it in the top view. Does it show the tool staying away from the edge? When you run the part throuh does it blend good? Just wondering if this is only a verify problem.

Running right now, Let ya know in a few. I verified yesterday when it was working and it cut away all the extra stock, and the actual part blended perfectly.

Try changing your verify options:

Switch "Tool Profile" from "As Defined" to "Auto"

and see if it makes a difference....

no difference

I noticed that verify also shows material left

after i do surfacing paths then em out a sharp

corner. but the CNC machines it correctly

 

I think the (3rd party) verify needs an update.

It is a big improvement from X2 to X3

At least it doesn't show a gouge.

One more thing,,,,,,,,

Set "Tool Tolerance" to .0005 in verify.

(I think the default is .008??)

See if that helps.

Looks like the tool tolerance adj. made the difference. The actual part blended perfectly. I just can't figure out how it worked fine in verify yesterday having never touched either of those verify settings. Oh well Thanks KC

Try turning off roll around corners. I have sometimes noticed that it makes verify look funny, but it seems to machine OK.

Certain tools will just not verify correctly for some weird reason..

We draw and scale all of our tools with the spindle

(A whole other subject...)

With the default settings in verify, the tools look like friggin' stop signs! (and verify that way too!)

Always have to switch "Tool Profile" from "As Defined" to "Auto" and keep tool tolerance way down.....

Mine is set at .0003 but I still have but the one

issue

Thank God I ran across this post. I did a 5-axis toolpath and when I verified it there were steps in the wall. I have spent HOURS trying to figure out why.

 

I checked my tol. and it was set to .008 as you mentioned above. (My network admin. came and reset all my settings to their defaults last week thinking this would resolve other issues - without asking me) Anywey, I changed it to .0005, reverified, and the steps are gone.

 

Thanks.
