Have you tried making a stock model from the previous ops?

 

Then you can set the stock in restmill to the stock model

[danielm]

Yes I have.  I really think that my problem is my lack of experience with Optirough and dynamic optirest.    I just need some tips because I cant explain why I'm getting the results that I am.  Like little patches of toolpath here and there...nothing that makes sense.  The real bitch is how many times I've waited 20 minutes for it to crunch the toolpath and all i get is xxxx.

 

 

[danielm]

maybe I shouldnt even be messing with optirough?  Any ideas?  Anyone?

[Leon82]

Check for a setting skip pockets smaller than ....

Maybe it has too big a value

[danielm]

Did you take a look at the mcam file?  

[danielm]

alright.  $20 in someones paypal for a working tip for this problem?  six pack of corona? 

[Leon82]

No, idont have internet access at work. I was throwing out random ideas.

For the detail work left in those corners you shouldn't be using Opti-Rough. I would use finishing toolpaths and just change the amount of stock to leave for each amount of stock you want to leave. I would make my finish toolpath for the area you want done. Use a boundary to isolate the area you want to finish. If you think +.03 is a good place to start then start there and work you way to the finish size. Start working down with the same tool path you copied just changing the amount of stock to leave for each one. If you have 5 axis abilities with Mastercam then you can use the Moduleworks toolpaths in 3 Axis that will respect the stock model and semi finish and finish the section respecting the stock model. Far as I know nothing in the finishing toolpaths from Mastercam respect the stock model with regards to not over engaging the tool. The module works will to a point, but you have to set the toolpath to do it.

Really?  That would eliminate the best resource for information, communication, etc at just about every decent place ive worked.  Sorry to hear that Leon.

I agree

[danielm]

my best so far. looks pretty ugly.  This is Hybrid using a previous operation as the stock.

[danielm]

For anyone following this problem of mine...it looks like a 3D Finish Blend is the way to go.  I suspect that I'll be using this approach pretty regularly for future mold detail work.

Gave me exactly the toolpath that i was hoping for. ...
