Excessive traversing between pocket milled holes

[terence_ibert]

I have 300 holes for a waste board with embedded T-Nuts.  For each hole there is actually the wider recessed bit for 3/4" in diameter followed by a smaller 5/8 diameter for the length of the t-nut followed by 1/4" diameter for the remaining amount of material thickness to the other end of a 3/4" MDF board.  When setting up a CAM tool path, Fusion mills the top holes separately from the deeper holes causing a lot of traversing of the machine between positions instead of simply milling all 3 before moving on to the next position.  I am not able to change this behavior.  Is there something I can do?  Currently the algorithm is extremely inefficient.

I've enclosed a screen shot of the tool paths simply selecting 3 hole sets.  This looks even messier with the full 300 on the board.

With 300 features to select, this may not be the optimum solution but you can change the order of machining using this switch.

I already tried the “preserve order” option and it made no difference. Could there be a bug?  The sample I provided is only 3 hole sets out of 300 for this example for my request for help. Each hole set has three contour shapes (circles) selected (so 900 separate cuts in total).  The only way I can achieve minimal travel is to manually create 300 separate tool paths.  Not at all practical.  I hope there is a better way.

We'd (hopefully) be able to give you a much better answer if we could see the file.

Please see attached.  Under CAM (Manufacture), the example tool path is "2D Pocket - TEST".  I've suppressed the rest.  The hole edges were selected by set and "preserve order" is turned on.  I'm trying to get the milling to complete each hole set separately before moving onto the next minimizing horizontal travel.  The three sets of holes were selected in sequence to do this but the 'preserve order' doesn't do anything.

Well, this certainly is NOT behaving as I'd expect. 

As a work around for this part, here's what I would do (actually, I'd do this anyways because I'm lazy energy efficient)

Pattern.

Just make your all operations for 1 hole and put them into a pattern.

@seth.madore  blame the slow forums today. Your post was not up when I started.

I strive to be energy efficient too.  thanks for the input
