The CAM is from Fusion 360. Lengthy discussion of the difficulties of milling acrylic and some solutions: bit getting "sucked" down. Shapeoko Z-Axis Plate Upgrade; Shapeoko Spindle Adapter; Shapeoko 3 Wasteboard layout; Shapeoko XL Wasteboard layout; Shapeoko XXL Wasteboard layout; Tooling Support. the bit has 2 flutes (cutting edges). [156], List of alloys and their characteristics: http://www.emachineshop.com/machine-shop/Brass/page322.html 353, 360 and 385 noted as suitable for machining on a CNC router. If your cuts are making the wood darker and/or producing a smell, try using a faster feed rate or a better bit (a 2-flute carbide endmill works very well, 2 flute end mills with TiAN coating are suggested[275]). [267], http://community.carbide3d.com/t/adaptive-clearing-on-pine/8813, SO3: 3.2mm flat 2-flute And any combination. You can't choose an optimal depth and adjust the width to compensate as normal. Depth per pass 0.020". You will notice a difference depending on the direction your mill is going. "[282], tests of different cutters in Baltic birch https://community.carbide3d.com/t/baltic-birch-plywood/2222/38 [283]. Single pass, 0.080" depth[289]. 3 flute straight bit Getting good Speeds and Feeds is quick and easy: Fill in the blanks left to right, top to bottom and G-Wizard instantly returns the best Spindle Speed and Feed Rate. Eventually, I will do similar tests to determine the best feed rate and other parameters for cutting 2D contours in MDF with a 1/4-inch bit. AU4G (2017) is really good at machining : you can take deep passes (~0.3 to 0.5mm) at something around 500 to 800mm/min (20 to 23 ipm). This is the opposite of routing, in which we're cutting parts out of sheets, so most of the time we have no choice but to have 100% radial engagement (full width of the cutter is cutting). This is less than optimal, and means that we have to cut shallower to compensate. Spread the piece w/ petroleum jelly to minimize dust. 1. Using a 1/4" 4 flute carbide from Kodiak (AlTiN coated). [145]. Flute Length: I'm cutting 10mm in 3 passes with good results.[195]. Every machine/set up is a little different…find YOUR sweet spot.... 10k to 15k rpm [121]. If aluminum “galls” on an endmill, a bathroom drain clearing product (such as Draino®) may be used to remove the material (please check the chemistry of this first against the composition of your end mill and its coating).
