Dynamic OptiRough Z Depths Issue

[Spotterhphc]

Hello Mastercam world,

Has anyone encountered a "Z" depth issue with OptiRough? A few times now i have had parts that had multiple depths of floors and when i go and select the  "steep/shallow min and max" z-depths and generate the operation it will not leave the appropriate amount of "stock to leave". I wanted .01 on everything and on some floors it would leave that amount but others it would easily leave .100 or more. Even when using "stepup" ,thinking it would come back once it goes beyond that depth, it still doesn't. I messed with it for quite a while and never got it. I have also seen this issue on Surface Finish Contour. If this topic has been covered then i apologize. What am i missing??? Seems like when you select your solid and it asks for stock to leave that it would actually leave that amount everywhere.

 

Thanks in advance.

Adjust the step down and step up so it will hit those depths.

Make sure your step up distance is such to hit the levels your step down doesn't get.

Little bit of math involved...include stock in step down number.

And if that doesn't work, build some offset surfs and don't use stock....

What I have found is breaking up features that are not connected into individual HST operations. Trick sometimes is getting the right depth of cut to the features. May has as much as 256% step down with 5% to 7% step over. Then sometimes might reduce to 125% step down. Trial and error sometimes finding the right mix to get what you need.

I have messed with DOC some but maybe not enough. Have you found that RDOC plays into how it process's the depths of floors? I suppose there is a lot that goes into processing the toolpath.  Thanks for the response by the way. :-)
