Select order of pocketing and locations of stock hold-downs?

Hi Julie

This has been very instructional and helpful in a difficult subject.

I was wondering, if I were to have multiple pockets (arrows), is there a way to select the order that Fusion 360 uses to create the pocketing? I tried to select them pockets in a specific order but Fusion 360 seems to create an order that doesn't make sense to me.

Also, is there a way to define stock hold-downs so that the beginning and ending tool paths will avoid the hold-down. I noticed that the is a fixture check box in the initial setup dialog box, but it appears that one must create of import vises, and other clamping tools and include them as part of the drawing. What is the best way

If you have multiple pockets, there's no way to control the order within the same toolpath. However, it's easy to create just one pocket, duplicate the toolpath (right click the Pocket toolpath, and choose Duplicate), edit the duplicated toolpath, and change the toolpath geometry. You can do this multiple times, one pocket for each toolpath, in order to control the order in which Fusion tackles them.

You can indeed define fixtures, but you do need to bring a workholding model into the file. Many vise companies offer free solid models of their vises, or you can model hold-downs like toe clamps or strap clamps yourself. Make sure the models are accurate, ensure you've located them accurately relative to your stock, choose them as Fixtures in your Setup, and then Fusion will give you accurate collision data (ie, tell you if your tools are colliding with your vise). In general for a beginning project, I recommend using brass screws in your stock, far away from any toolpath, that firmly attach your part to a spoiler board (waste board). Then, use your hold-downs on your spoiler board. In this way you can keep your workholding system far away from your stock and help prevent collisions. Brass screws are good to use because they are less likely to damage endmills, in the case that you accidentally machine into them.
