What's wrong with this part?

[hualon]

I have a relatively simple file here that isn't cutting properly. I'm using a 1/2" cutter to do four operations: two pockets and two contours. The resulting product is a clamshell box.

When I run the "Verify", the part seems to be right but the actual part has a defect. The walls of the box should all be roughly .25 inches (.2431) but the bottom (on the x axis) winds up being far thinner... like .125!

Does anyone have any idea why this might be happening?

I attached the mcx file but I made the extension a .zip. Could you look at it (rename it to a .mcx first!)? Thanks!

edit: I added the .nc as a .txt file.

If you could post a version 9 file I might could help you.

I do not see that one all is .249 looks like it may be drawn wrong.

hualon,

Can you tell me the blank size and where the X Y Z zero is located. I will run it thru vericut and check it out.

Bottom left corner X-.25Y-.25

Stock is about X19.5 by Y11.5

BTW: I couldn't see the problem with a quick NC Plot and didn't look with Predator. Maybe you will see with your solid verification.

Toby,

When refering to a stock size there are three dims: L X W X D. D being the thickness of the material. Same goes for the X Y Z Zero location. I need the Z Zero too.

[hualon]

The stock is 12x20x.5". I zero at the top of the material.

I'm pretty new to all of this as you can probably tell. I think that the problem might be in where I'm setting the zero for the y.

Ooops!!! Looks like I need a vacation. Sorry about that.

Watching multiple tabs in the browser (yea that's right blame it on the tabs).

LOL glad I'm not at work today

hualon,

Please look at this PDF and let me know if the dims shown are correct and the zero is in the right spot.

[hualon]

That is correct.

Ok thank you, I will check it out and let you know what I find.
