3400rpm/.002 per flute with very small end mills. Will fume if heated, wear respiratory protection. Quora: What are the best ways and practices to clean acrylic or plastic parts after precision CNC milling? Note: RPMs have been regularized against the Router Speed Chart (see below) using the Dewalt dial setting as the standard. If you are making sawdust the speed/feeds are to high. Only limitation is they are typically quite thin, usually not greater than 1/4"(6mm) thickness. It’s very similar to the #201 that comes with the Shapeoko but it has two flutes instead of three. 1.000 in Carbide's #112 with a depth per pass of 0.008". 68.3 in/min cutting feed rate (feed per tooth .0046") I left a 0.5mm of stock then did a finishing pass at 500mm a min[297], from: https://www.facebook.com/groups/unofficialshapeoko/permalink/386992208375411/?comment_id=387217465019552&comment_tracking=%7B%22tn%22%3A%22R%22%7D. The typical (ideal?) Static may be an issue. October 2018 20-30 IPM [186]. I have those exact 60 and 90 degree bits and get a very ugly cut on the bottom (think about something between tear-out and a fuzzy bottom) unless I slow it WAY down. Lubricant (dish soap is suggested at: https://www.reddit.com/r/hobbycnc/comments/fhzo9i/thank_you_for_all_the_help_with_acrylic/ ) may help. Using a Dewalt DW660 on a ShapeOko 2, Riley Porter was able to cut 3/8" plexiglass[218] with the following settings: eShapeoko: 21kRPM, 800mm/min at 2.5mm deep[220], Re: Cutting plexiglas with standard Dremmel. 1/8" four flute solid carbide endmill. 690 (Southern Yellow Pine, Loblolly and Shortleaf) Note that lead will bio-accumulate, and dust must be handled with that in consideration. September 2018 Edward (Ford, the machine's designer) has posted an aluminum milling video with the S3 with good finish and parameters that FSWizard spits out about 4 pounds for. Feed 400 mm/min Plunge 170 mm/min RPM 19000 and coolant Trichloroethane whit good ventilation. The main concern when cutting MDF is that cutting will yield a lot of airborne sawdust (which, due to how MDF is made, can be harmful to to inhale). ~15,000 RPM Calculations done using http://www.productivity.com/resources/calculators/. Note: Many of the early Beginner’s Examples use a small Shapeoko … [191], "The 34 mm/sec with a 1/4" flat cutter at 3.17 mm step was way too fast. They'll say "cut at 1/2 your cutter diameter," or something along those lines. dewalt set to 2.5 (very conservative)[188] Video. Aim for 0.001 to 0.0007" chip load [64] 0.00075 in/tooth (12.5 in/min) or better yet, to 0.001 (18 in/min) @9000 RPM suggests. What I'm saying is, every machine will be different and hard to predict.

We Real World Tested 30+ materials, Plastics, Woods and Metals. (I'm not vouching for 0.004" necessarily being an appropriate chip load for acrylic. March 2020 [108], Using the upper pair of mounting holes on the spindle carriage plate may reduce chatter. Pay attention to chips on the hardwoods. Any cutting or fabrication involving fumes or the potential for fumes must use suitable exhaust hoods and filtration. Note that boards which are molded (as opposed to cut) may be swollen or otherwise out of dimension along the edges, or somewhat shrunken towards the center, depending on how they are cooled coming from the mold. Use very sharp cutters with copper. [192], "6.35mm square endmill (#201 from Carbide3D) => 12000 RPM + 1250 mm/min" [193]. You can go back and do a 'finishing pass' just a hair deeper at slower speed to clean it up. Spread the piece w/ petroleum jelly to minimize dust. Material Wood-Hard --- settings transcribed from CC433. June 2019 No lubricant. I'm cutting 10mm in 3 passes with good results.[195]. All the credit for the chart itself belongs to other users on … Primary consideration is how fast the flutes of the cutter move against the material. Tool settings: .127mm DPP, .020mm Step, 200mm feed, 100mm plunge, .050 OAD. If the deflection at the tip of the cutter (cutter plus whatever it is attached to) is more than the thickness of the chip, (feed per tooth) then it is guaranteed to chatter, and not cut well. 1/2 endmill: 100ipm, 30 plunge, 3 on Dewalt dial. use a spray adhesive such as 3M Super 77 --- follow the directions. DOC: 1.016mm (0.04") (Carbide Create: 0.7 mm), Feed: 1397 mm/min. |Carbide Create. This will bring your work surface exactly square with the machine.

April 2019 Many steels work-harden, especially austenitic stainless (e.g. 2F end mill at 12ipm with 5 speed (DWP611). This is the protocol I use for walnut stool seats, about 18 x 16 ovals (I have to orient them 45 degrees to get an 18 wide oval). Thickness tolerance for typical manufacture is 0.02", engineering plastics are available w/ tighter tolerances (0.005" from McMaster-Carr). Dust is conductive and potentially hazardous. Info: Usually seen as bars, rods, tubes, balls, and discs. For deep slots reduce the Ft./Min. 2.0 0.05" Step Feeds and speeds.

RPM: [112], 1/8" 3 flue 45 deg helix upcut mill made for aluminum. The thing at this point in time that will break your cutter is excessive cutting forces, which come from the last variable in our cutting equation: depth of cut. Cast PMMA is essentially pure polymethylmethacrylate and machines well using, when possible, tools with zero top rake and a very sharp cutting edge. [141]. [176] Other machinists note it works much like soft brass.

It’s long enough to cut 3/4. mill fast speed with low rotation speed. Happy cutting! Feed Rate = 60 All The feed rate represents how fast the machine will move the router bit though the material when cutting and is critical to get right for leaving a good quality cut edge. 80.0 in/min [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. 0.001143″ (mahogany), http://www.wood-database.com/wood-articles/wood-allergies-and-toxicity/ [254], http://community.carbide3d.com/t/drilling-with-the-shapeoko/7405/13, https://www.reddit.com/r/CNC/comments/3f2plb/need_some_advice_on_machining_hardwood/ctktfj4, Hardwoods: 1mm endmill --- 0.5mm cutting depth with 500mm/min feed rate at 16000 rpm. Now, if you take a big-enough chip, the next cutting edge is biting into the material below the hardened zone, but with a very small feed/chip thickness, you will plough precisely through that thin sliver of the surface that the previous cut just hardened. It is why steel and to a lesser degree certain non-ferrous alloys are so difficult to cut. The below are the settings for MDF from the pixel image chart which was initially put up by Carbide 3D on their docs.carbide3d.com Support | Tooling area: Note that some users have specified 5080mm (200in.) Woodworking Projects, December 2020 ~15,000 RPM | () I use a thick (>4mm) piece of aluminium larger than what I need to cut, clamp that to the wasteboard and then dab a few drops of standard cyanoacrylate superglue on the thin sheet and slap it to the larger, thicker piece.
