Unwanted extension milling open pocket

[Anonymous]

Can anybody tell me why I have this extension at the end of the finishing pass in depth and before the radial finishing pass ? It causes the end mill to enter full depth into the stock.passes settinglinking setting

Your tool path seems to be all over the place, what are you using as geometry to outline pocket?

Are there tangential extensions involved? Why not draw a sketch and use it as geometry to contain tool path?

Looks like you are using contour and passes rather then pocket.

I just selected the face as pocket selection in geometry. Why should I draw a sketch ?

Tangential extension is a feature of 2D contour, I am using 2D pocket.

Why are the paths parallel instead of concentric, I don't know but the result is correct except this little path instead of just going up.

In 2D pocket you select edges of model or sketch, not faces. If you select edges of blue face tool will leave unfinished corners, that's why you would create sketch that extends past the edges for tool radius value and and use that as geometry.

Right now all I see in your picture is one edge selected, thick blue line.

So it's a bug that Fusion lets me choose a face if it is invalid. But the result is correct except if I choose a finishing path.

If I choose the 4 edges as geometry the paths are more conventionally concentric, but it's another bug that Fusion forget the corners.

I expect from a good software to do what I want, not to do what the software wants.

Well, before we start claiming bugs and because there was an update, I was not sure if what I sad was all on target so I put it to test.

I can click on face, select individual edges, select sketch that overlaps model, select inside of sketch or select area between two sketches.

Without looking at your selections shown in above post, I could not duplicate your "BUG" with routine few strokes, I guess that makes me underachiever but I don't see anything wrong in 2D pocket operation.

In first operation, clicking on face seems to select only one edge but tool cuts entire pocket and it overlap edges, looks like added functionality.

Selecting individual edges leaves corners uncut and tool is contained within pocket.

Selecting sketch forces tool to overlap edges and finally selecting 2 sketches contains tool inside selected contours.

Yes the issue is still here. As I said it happens just before (and if selected) Finishing Pass. 

Here the setting is with Finish only at Final Depth, if not checked the extra path is at every depth.

And no lead out. If checked, the last one still goes further, even with your setting.

I already noted there is some proficiency here to call bugs added functionalities. At least it is messy UI.

I am well aware that I can draw sketchs and calculate square root of 2 to workaround added functionalities.

Since you don't share your file, I can only talk about my file because I can only work with my file.

Here is scenario in which I used finish pass within same operation, it only runs finish pass along selected edges, not the entire pocket, so if i want to finish entire pocket I would duplicate operation and assign different parameters.

Bug or no bug, there is nothing that stands in my way of doing what I want if I explore options, drawing sketches is extension of selecting model edges and that is very functional and useful option. 

I don't recall claiming you cannot take square root of 2 so you leave me scratching my head on that one.

Checking both results in roughing to final depth and then running finish pass only along selected edge but stock is already gone.

So these settings seem to be contradicting each other in function, but i can still do what I want by not selecting options that don't lead to my objective.

Fusion has numerous bugs and imperfections but I can still produce tool paths of my choice, some bugs are years old and still there, report your bugs to Autodesk and hope that they gain some priority in near future.

But the last post was using your file.

It is normal that Finishing Passes run only along one edge because it is lateral (axial) finishing.

The reference to square root of 2 was simply to point out that you have to do some maths and draw a new sketch to use some unfinished functionalities witch is not very satisfying for a professional software.

I have no problem with Finish only at Final Depth witch refers to lateral (radial) finishing.

Rough Final refers to depth (axial) finishing. What's weird is that unchecked the finishing pass in depth is not done, checked it is.

All this window Passes is very messy, bad naming (and I don't speak of Finishing Stepdowns versus Finishing Stepdown), bad organisation, relationship between parameters...

But I remain convinced That something is wrong with the generation of paths. To give another example, why in your model the different lead-out (or lead-in) are not at the same X position ?

Bug or messy UI I don't know, but one thing I know for sure is that each time I do something slightly  different from before I have to spend hours fighting to find a workaround.

OK, best I can tell you is that I go after results I want to see and if then something stands in my way, I call it a bug and I raise some noise over it.

It is a public secret that Fusion is in development and has many issues that need attention from a development point of view,.. and someone is banging their head against the wall to catch up with all of our pissing and moaning.

The good news is that there is progress and we are not paying $20000 for using whatever is functioning.

I can list dozen bugs in turning that are still there but I can also get around them and get things done every day.

On subject of sharing experimental files, new users in particular tend to list page full of stuff and upload pictures but don't share Fusion file.

It is very annoying to read all that and forget what was at the top of it by the time you read last sentence when best and most effective way to get someone to engage in figuring things out is to upload Fusion file.

Sorting thru dozens of settings and connecting dots while only the poster has full information is sort of game that is not very productive for that poster in general.

My file can be altered in many ways to generate problems but only one I cared to mention is conflict in checking two boxes that contradict each other in function, I never produced that extended tool pass and really don't need to look for how or why it occurred in your file or my file under your scrutiny.

Get comfortable with term "workaround", yes we must do the thinking and finding alternative ways to get things done.

So if you focus on getting things done, you avoid those known and newly discovered problems, someone else's job is to study reasons why they occur and coming up with solutions, reporting bugs is as far as user can go.
