MC9-Define Plane menu. Where is it?

[neilw20]

1). How do you get to the Define Plane Menu. It is in the help.
Then I want to define a plane to limit bottom of cut.
Is that a Check plane?

[cadcam]

Are you trying to limit a surface toolpath?
there is depth limits were you do not have to pick or define a surface as a limit ,but just a amount.
Picture.

I found the limit you mentioned, but the one in the help...
I am just trying to get my head around the strange interface.
It's in the help but cryptically hidden by the programmer

[cadcam]

That is a thought of setting planes to cut in or draw in not to control the depth cut.
is that what you want is to draw in a defined plane?

Mr Cadcam.

What I have is a strange curved bumpy shape, and I want to start with a solid piece of material holding it by it's ends and machine the shape as a cavity almost to breaking through the base using a ball nose mill, then go around the outline with a square ended mill mill to break out the finished part.
That is I need to define some fences to keep define the outline of my cavity, with the required shapes jutting up out of the cavity.

Thanks. Neil

Do you know about creating tool boundary's? this will contain the tool in the cavity area.
Are you tool maker?

Neil can you share you V9 file with me? if you want you can email to me. I have to off for some Cubscout stuff then will log back on.

Here is the file to you. It is an IGS file and does not come up as a solid, so this makes it a bit more difficult. I want to use a 3/16" ball nose cutter.
There is a second file (AICS.sat) I am trying to get a handle on too. It uses a 1/2" ball nose. I really appreciate your prompt help. Slight delay due to fact that SYIL Aust just rang me. I get involved with their faults.
Same strategy to make. I am going to make two of each, sliced through the middle and glue them together (today I hope.) Machined out of 18mm x 140mm Flat fine grained particle board, so 250mm/minute at 1800 rpm is good.

Do you need any electronic assistance?

Thanks. Neil

[cadcam]

The Iges has bad surfaces and many holes hard to work with the other I can work with.You want this in V9 correct?

[cadcam]

Please review picture

Need cavity 18mm deep with 15mm hook thing sticking up as an island.
Then the final cut will give me half a hook. Then make another and glue them together. Both items are of a similar nature.
Thanks Muchly.
Neil.

Neil I have to say I am confused what you want. as you say you want a cavity byt you want the hook up as a core.Please help me help you.
