Milling surface with holes

[Scot]

Hello,

 

I did a search while not finding the below question although I'm sure it has been asked many times.

Which way would you recommend milling a 3-dimensional surace with holes in it? I am using suface finish scallop to mill a surface with holes in it. The tool tip wants to go inside the hole. I would like the surface to be flat for drilling. Other suggestions would be appreciated.

 

Thank You,

Scot

you need to create a patched surface to cover the holes. I think its Create,surface,trim-extend,fill holes

Also try create,surface trim/extend remove bndy,slide arrow to hole.

 

Can also create,surface trim/extend untrim this will give you the Parent surface.

I should have probably noted that the parts I work with are created in Pro and then converted to an IGES with either surfaces or wireframe.

 

Mayday, if I followed you correctly, the only setback was that I had to go back and select the filled holes as drive surfaces. But otherwise it worked wonderfully and extremely quick.

 

Either way, create, surface, trim/extend, remove bndy, and sliding the arrow to the hole worked like a charm for my particular application.

 

Thank you both for the help.

 

Greatly Appreciated,

Scot

If it's a solid, try:

 

solids>next menu>find features>holes

 

make sure you enter a decent radius range.

sorry, you beat me! Glad it works though.

Be careful with remove boundary, make sure you save your file before you do it. It may give you results you weren't planning for. At the same time it is a great tool and couldn't live without it.

Scot, you have moldplus, if you open up the suprtrim chook all of the surfacing tools from moldplus are right there so you don't have to hunt for them. There are some really good tools in there for working with holes and gaps on edges.

Scot, you have moldplus

why didnt you say that in the first place Roger? I coulda saved Scot some work

Hey gimme a break I've only had one cup so far...

I always add a surface in pro to cover the holes before I import them into mastercam for surfaceing. If you change you defualt color in pro the surface will show up differently on import and you can easily layer it off in MC

I will unblank the parent surface and use the containment boundry and machine away. Usually put all parent surfaces on level 255 and then move the parent that I want to a Surface Toolpath level along with the containment boundry. This has been faster than using the fill holes. You can also window the surfaces to select to get them all. Takes longer to generate with overlapping surfaces, but cuts only the highest one.

I have a similar problem.

I have a sheet body solid, and cannot fill holes.

How can I work around it?

I need to do a boolean remove,but I get an error.

[DavidB]

Jeff,

Create an edge curve on your solid sheet body and then use the curve to create a surface.

Thx David,I'll give it a whirl.

FLat boundaries work great for flat holes or the fill hole. You have to watch that one sometimes also it might not give you the result you want.

[crazy^millman]

What I have done is create a surface where the hole is. I then untrim the surface. I then use a chain or circle that repsent the boundary of the hole and trim the surface to it.

 

 

If I had Pro I would do all my work there save my soild or Iges but if it were me solid only with the features supressed then you ave a couple different features like you want all done and will get much more predicatable results this way then the patch and fix method gone over here.

 

Just my humble opinion.

[Scot]

Thanks for the replies. I am now aware of many options to try. Great Ideas. A ton of help. Sometimes I get too busy and overlook the obvious. Supressing the holes in Pro will most likely prove the quickest method.

 

Thanks Roger...I should have asked you first, but I hate to bother you for every question. I use moldplus for some other modifying features, but I will have to explore it more often.

 

Thanks Everyone,

Scot

This problem shows the best reason to have Mastercam Solids. The "Solids - Find Features - Holes" is a GREAT function to remove holes for 3D machining.
