gouging

[tonyjohnson]

mastercam seems to gouge alot.Ive scraped a surface job with the filter on and off.whats up with 9.1 . The tolerance is .0003 .I had to shift the guilty tool up in Z .012 to remove the 2 gouged areas on a dome shaped surface.Will some mold guy help me out?

Dome shaped... is this a revolved surface? Was it created in something other than MC?

Always beware of revolved domes, even if they are made within Mastercam.

 

Copy surface and trim to a line so you have 2 surfaces.

 

This will result in better math on the toolpath.

The suface was created in solidworks by my customer and I had it checked out by a MC dealer.I have many surfaces in the file .Seems the arc moves are not very acurate.The gouges are EGG shaped instead of being round.

I would recreate the problem child....

 

+1 to Murlin.

Beat me to it billh....yup....dat's what I would do...

What about the ARCs in the code. How do I get rid of them in exchange for long hand code.

If using V9, you'll probably have to disable arcs in your post. I'll have to get back to you on how, unless someone beats me to it.

 

If using X, go into your control definition, under Arc and uncheck Support arcs in XY plane,

Support arcs in XZ plane, and Support arcs in YZ plane.

Ahh, well not having your post dialed in on arcs in a diffrent problem.

 

 

You can change these param's

quote:

---

breakarcs : 0 #Break arcs, 0 = no, 1 = quadrants, 2 = 180deg. max arcs

arcoutput : 0 #0 = IJK, 1 = R no sign, 2 = R signed neg. over 180

arctype : 2 #Arc center 1=abs, 2=St-Ctr, 3=Ctr-St, 4=unsigned inc.

do_full_arc : 0 #Allow full circle output? 0=no, 1=yes

helix_arc : 2 #Support helix arc output, 0=no, 1=all planes, 2=XY plane only

arccheck : 1 #Check for small arcs, convert to linear

---

And in the filter box, you will need to turn off arcs in the y&z....

 

You will need to refrence your control manual for code examples....

Is it guoging in verify or just on the machine?
