There's no Roughing/finishing option?!?!

[ajinjax]

What the heck?

I'm just getting into this software and I'm stupefied trying to figure out how to get Bobcam to create a roughing pass program and then a finishing pass program.

I see they have a 3d Offset tool. Which would be fine, if it worked.

When I try that I get random lines shooting out in all directions.



Anyone have suggestions on how to work around this?

My thinking is to trick the machine by telling it to use a larger tool when creating the program and actually use a smaller tool. Then write a "finishing" program with the correct size tool.

Would that work?

Bobcad version would be helpfull.

If you have a sample file it might also help.

For 3D roughing and finishing that is the way I do it with tool diameter.

In 2007 there are settings for this so you do not have to lie.

I'm using Version 21.5.3

Then the only option for you is to lie about tthe cutter diameter when 3D milling. Also translating the part in Z to get just Z stock.

I am not sure about those crazy moves. Would have to see the file to find that. i used 21 for over a year and do not remember getting paths like that.

I think I know why it is making those lines.

The program I created the solid model in, Vectorworks, can't seem to make a 3D fillet correctly.

On a .125 step I couldn't make a .125 fillet. In order for me to make the fillet I had to make the step .126. So there's a .001 face just above the fillet.

I think that's what is freaking Bobcam out when it tries to do the offset.

Did you try to use Bobcad to create a fillet? It may allow it where your other does not. Hard to tell.

Also if you are using a .25 ball mill them you do not need to create the fillet as it will be there by the tool radius anyhow.
