Pocket Rough

[Lukas]

Hi Guys,

 

I'm having an issue in mastercam x7 when defining chains for rough pocket machining.

There is an option to choose containment chain, where as I've seen on some tutorials, is a possibility to pick stock material as a chain and machine everything all around previously indicated model surface. For some reason my mastercam is not recognizing stock as a possible containment chain and I can't go any further with machining my part.

 

Any ideas how to fix it?

Hello Lukas, welcome to the forum

use the surfaces to "create>curve>curve on all edges". You may have to clean up any duplicates including splines that may not be exact duplicates but are overlapping. then use the containment option to chain the new curves.

I use silhouette boundry alot.Just set zplane 2d above part ,create silhouette boundry(pick surfaces ) that should give you what you need.

The idea here is that the boundary is wireframe and not a face or solid shape. You have the ability with HST toolpaths to have them look at stock and then they will make the toolpath according to what is left or there, but Surface Rough Pocket is just not made that way. Great toolpath used it for years, but HST is my go to stuff now. Great suggestions above and think once you dial in the process you will see how to apply what you need.

So you know just set the Z height you want and use silhouette boundary you do not have to set it to 2D just select solids or surfaces.

yes jay that is true I just like to keep my boundary up so I can see it clearly from the part.I thought if you used 3d it put the boundrary right on top of the part

Wow what a great feedback guys!

Looks like silhouette boundary solves the problem. That's exactly what I meant!

 

Now finally moving on with my thesis! Thank you!
