I'd like to cut about HALF of the contour (the TOP half in the picture below), plus a couple of grooves out to the side of the stock, remove the waste, and then hold down that half of the piece with some kind of bar or strap clamped across it, or perhaps across each of the two corners, and have the shopbot continue to cut out the remaining contour. If I now cut the contour, it'll leave my workpiece in a state where its held down by only those two screws, which doesn't seem like enough to me. 15K views 7 years ago Fusion 360 Quick CAM Tutorials. I pause, and insert two more hold-down screws (with washers to distribute the load) into those two holes. With the shopboat, I cut the two holes and the two partial holes in the design. I try to follow the first 3D pocket operation with a 3D Contour operation but can not figure out how to get this done and keep on getting the warnng. Share tool strategies, tips, get advice and solve problems together with the best minds in the industry. To select and edit contours: In the geometry tab of a CAM operation, select the drop-down icon for 'Add geometry feature'. I start with a 24 x 24 sheet, and near the edges put in 8 screws (corners and mid-edges) into the spoilboard. Talk shop with the Fusion 360 Manufacture Community. Solution: To select open contour by default: Hold the Alt key (Windows) or the OPTION key (Mac) while selecting the contours. When machining components, it’s vitally important for the CAM programmer to have control over all aspects of the toolpath, to ensure quality, efficiency, and safety. It's got two holes about an inch from one of the edges (and two partial-depth holes next to them, but that's irrelevant). Dylan Smith Febru3 min read The ability to control the entry points of toolpaths is a must for CAM programmers. I'm building a (roughly) 20 x 20 inch rounded-corner square from 1/2" plexiglass (see below). Talk shop with the Fusion 360 Manufacture Community. I need to avoid machining off the boss with the hole in it, so the contour takes in some edges from that feature. I'm a complete novice with both Fusion 360 and the shopbot, having made exactly one part with each. Contour selection may be at the root of the problem.
