2021 Optirough vs. Optirest

[kccadcam]

Mastercam 2021:    Select Optirough, set Toolpath Control, Strategy: "From Outside"
As soon as you select the Stock checkbox to turn it into Optirest, the Strategy greys out and defaults to "Stay Inside"
 
How do you restmill from the outside now?

Create a boundary chain and compensate to outside.  

Some times I wont bother using a boundary and check the results depending on the geometry.

So how good are these paths really?
We have more 2D licenses than 3D so we don't use this much, since the next guy might not have an available 3D.
I see a lot of people using optirough paths on the forums for sure.

It's a pretty good path.  I have found a few things about it to be annoying, and don't work as expected.  Sometimes when using Optirest I randomly get crashes when using minimum retract, but if you verify things, it isn't a problem, as if you make a small change to the boundary, or something miraculously it will retract enough.  Remember, in 2022 release, your 2d seats with have access to it.

Overall, I'd say it's very handy for 3d roughing.  I prefer to use it for pocketing when there is a large corner radius at the bottom.  The step-up feature can generate the radius in a rough sense with very little work resulting in a very efficient toolpath, my only gripe would be with the reposition for step-ups, I don't like it having to retract all the way to the top of material.  Not sure what I am doing wrong, but it always seems to go up to the previous step down level.  Could be more efficient from that standpoint, just a simple blend spline would suffice.

Anyone have any luck using Approximate start point with this path ??

It will let you pick a point but then ignores it
















PEACE

Nooo waaayyyyyyyyyyyyy!!!
We are actually using the beta at work, I just tried it dayum!!

That's been my experience as well mostly.  If you are starting in the middle of a pocket it used to the point, but as far as from outside, nope, nada.

I think it looks at the starting point as more of a recommendation

It depends on the situation.

These paths are designed to take advantage of the length of flute of the end mill.  Once you start stepping up, depending on the geometry that you're machining, they can become very inefficient and actually harder on tool life.

Sounds like Reko...

That's cause you picked the wrong point
