[277], Geometry This page was last modified on 13 November 2020, at 09:21. depth per pass: .400mm A central tenet of this series is an acknowledgement that the hobby CNC routers need different numbers for different sorts of paths. 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.) .03" stepdown 1/8 single flute carbide end mill. Formatted as CSV files, they may be readily modified and shared. What I'm saying is, every machine will be different and hard to predict. Abrasive and dusty. Start shallow (won't hurt anything) and work down deeper and deeper until it sounds like your cutter is really loading down, then back off a shade and remember that value. fewer flutes, lower RPM, faster feedrate, also try coolant while milling (WD40, water or aluminium specific coolant fluid). It's actually the appropriate speed to get a good cut. Plus, the best training materials anywhere free with the product. October 2018 Now let's say my cutter has two flutes, so every time it rotates I have two chips being removed. [271], SO3: conservative feed and speed: 13,500 rpm, DOC 4mm, Feed 200 mm/min, 2 flutes 1/4 carbide bit. ​1/4 endmill:  100ipm, 30 plunge, 3 on Dewalt dial. Makita set at 3, ~16,870. ~15,000 RPM All values should be verified and tested on a scrap of material first, then one should adjust to match desired chip size and surface finish and time required for completion. http://community.carbide3d.com/t/carbide-3d-tool-112-1-16-endmill-speeds-feeds/6024/4, .062 endmill at the following settings: whit 0.063" cutter . Deals You have to take smaller passes (0.2mm) at high feedrate (around 1000 to 1200 mm/min, or 40 or 47ipm). 3 Hardwoods such as Maple, Ash, Basswood, Birch, Cherry, Walnut, Poplar, and Oak; Softwoods such as Pine, Cedar, Balsa and Fir Example 2: Feeds and Speeds that won't pop small parts off our vacuum table. Unboxing the Shapeoko. My Shapeoko XXL arrived in two boxes–a small one and a very heavy … Theoretical Feeds and Speeds . You might also need a different step down. Stepover was 50% with a 0.055" step down, and stock remaining set to 0.02". MDF (medium-density fibreboard) is a relatively easy material to cut. Delrin is the DuPont brand name for Acetal (Polyoxymethylene (POM)). If youre like me, you loath entering feeds, speeds and tool geometry into Carbide Create. 20-30 IPM [186]. Dec 30, 2018 - CNC feeds and speeds. It seems Gadgetman was on to something with single-cut operations vs choosing a roughing and finishing two part strategy. These measurements work for other soft hardwoods too, like Alder and may be a good starting point for softwoods. So I made a simple formatting change and I am providing the document here for anyone else’s single page printing pleasure. I figured it was time to start a list sharing the settings that have worked and produced good results for me. Single flute cutter, routers likely need lowest possible speed setting.[199]. It's soft and evenly composed, so the bit should have no trouble working through it at a consistent pace. Usually seen as bars, rods, tubes, balls, and discs. [122], http://community.carbide3d.com/t/why-am-i-breaking-my-bits/2875/8, 30 degree 1/8" shank v-bit. Step down was .2mm per pass, feed rate of 400mm/min. The Shapeoko uses our Carbide Compact Router or you can provide your own DeWalt DWP-611 or Makita RT0701C as a spindle. Further discussion here. Had a perfect cut at 12 mm/sec, 3.17 step and router at 4 makita with 1/4 " flat carbide3d cutter. Density ranges from 20--50 pounds per cubic foot. 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). the following settings worked best with a straight fluted bit. Feed is generally measured in Inches Per Minute (IPM) and speed … I run it at 10,000rpm, 20-30 ipm feed rate, plunge about 8-11 ipm. We've gone through the basics of Feeds and Speeds calculation. [53], https://engineering.stackexchange.com/questions/2413/high-spindle-speed-low-tool-pressure, (these should be conservative and are based on smallest from the larger recommendation and largest from the smaller from their chart), https://community.carbide3d.com/t/v-bit-feeds-and-speeds-poll/17077. 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. Increasing cutting speed will increase temperature in the shear zone. Lighter than Delrin and will not hold the same machining tolerances. I think it turned out decently and will be great for this project series. 0.008″ (pine), 0.00120″ (bamboo) -- dimensional letter shop sign, https://community.carbide3d.com/t/0687-eagle-carved-in-mahogany/15464/6, https://www.facebook.com/groups/232744457133521/permalink/302749516799681/, https://community.carbide3d.com/t/baltic-birch-plywood/2222/38, https://community.carbide3d.com/t/stabilized-walnut-inlay-for-a-watch-case/13901, https://www.facebook.com/groups/unofficialshapeoko/permalink/386992208375411/?comment_id=387217465019552&comment_tracking=%7B%22tn%22%3A%22R%22%7D, http://www.sculpture.net/community/showthread.php?t=3287, http://www.who.int/occupational_health/publications/en/oehairbornedust3.pdf, http://community.carbide3d.com/t/1-8-carbon-fiber/626/3, http://blog.inventables.com/2014/02/circuit-board-milling-on-shapeoko-2.html, https://www.youtube.com/watch?v=7R7PsCu5TZM, https://www.youtube.com/watch?v=0Yvcizt83DA, https://www.amazon.com/Toysmith-4801-Really-Big-Eraser/dp/B00KSGSOB8, http://www.surfscience.com/topics/surfboard-anatomy/materials/know-your-foam/, http://www.bois.com/media/192315/360x300-fraises.jpg, http://www.freemansupply.com/RenShape440Styling.htm, http://community.carbide3d.com/t/machining-materials-questions/482, http://www.sawmillcreek.org/showthread.php?213915-CNC-router-for-Plaster-Moulds&p=2227973#post2227973, http://www.camheads.org/showthread.php?t=3377, http://www.cnczone.com/forums/haas-mills/63483-anybody-ever-milled-hard-plaster.html, http://madmodder.net/index.php/topic,2729.0.html, http://www.instructables.com/id/Machinable-Wax/?ALLSTEPS, http://community.carbide3d.com/uploads/default/original/2X/2/2e3c9d6977a1fb9722b95424e054f90fc95d7fb9.pdf, http://community.carbide3d.com/t/home-made-machinable-wax/1209, http://www.walmart.com/ip/Presto-Kitchen-Kettle-Multi-Cooker-Steamer/14321003, http://www.cnczone.com/forums/hobby-discussion/26351-cnc-post210273.html#post210273, https://wiki.shapeoko.com/index.php?title=Materials&oldid=19259, Makita 15722.5 RPM calculated, Makita dial 3 at 16870 might be better, your machine and its configuration, esp.

Info: [137], cut on my SO2, with a feed rate of 300mm/min and a 0.1mm depth of cut... Dremel. One option for parts which can be cut quickly is to freeze the rubber (with dry ice or even colder temperatures) before cutting. |1/8″ #101 or #102 Engraving: 30-degree engraving bit with 0.0118 tip (0.3mm) (Amazon) Happens quickly because the heat can’t get away in this case, and the blunt tool only makes things worse (higher forces, more friction, more heat…). I get excellent tool life, and very little finish work. https://www.reddit.com/r/CNC/comments/5nj3xh/does_anyone_have_any_advice_on_milling_plexiglass/ --- mostly suggestions for flame-polishing edges. 4mm 2 flute carbide end mill for aluminium, Bits: .010 2 flute end mill, 1/16 2 flute end mill, alupanel (HDPE layer caught between 2 0.3 aluminium sheets), RPM: 17500 (Dial setting: Dewalt: 1.25, Makita: 2.8), Spindle = Stock shapeoko demel knock off at max, Pass depth was .045" for a total of 3 passes with .010" of over-cut into particleboard, RPM: 18500 (Dial setting: Dewalt: 2.5, Makita: 3.25), RPM: 18500 (Dial setting: Dewalt: 1.5, Makita: 2.9), RPM: 19000 (Dial setting: Dewalt: 2.5, Makita: 3.25), inexpensive things where coarse grain and the reddish tint is okay: red oak, more expensive things where coarse grain is okay, but colour should be more neutral: white oak, outdoor projects: cedar --- teak if strength and longevity are important and your skills are up to the value judgements involved in working with tropical hardwoods (see below), nicer projects where wood grain will be celebrated and a lighter colour is desired, but surface should be smooth: maple, nicer projects where wood grain will be celebrated and darker shading is wanted: walnut, heirloom projects where specific characteristics/appearances are needed --- this is where burls, veneers, and tropical hardwoods come into play, RPM: 19700 (Dial setting: Dewalt: 3, Makita: 3.5), Tool Diameter: 0.125 (2 flute .125 end mill), RPM: 21000 (Dial setting: Dewalt: 3.5, Makita: 3.75), RPM: 19700 (Dial setting: Dewalt: 3, Makita: 3), carbonized --- sort of reddish brown color. Produces more fumes and is even more brittle than cast acrylic. (55") (Carbide Create: 424 mm/min), Plunge: 584.2 mm/min. Many alloys (and the element itself) are "gummy" and difficult to machine. .5" 2 flute through bloodwood @ 0.2" stepover 0.2" stepdown 74 in/min. Now I can multiply that out by my spindle RPM (12000, because why not) to get 0.008*12000 or 96 inches/min. I had little luck with the any variation of the circular path, and it also does a very annoying z up movement with every completed Z level. any upgrades (but information for stock Shapeoko 2s and 3s would be especially welcome), actual feed / speed and the unit of measure (mm/sec in/min etc), whether or not you had dust collection active, TI-85 --- noted as having many conversions, harder materials (steel and cast iron and harder alloys): 8 to 10% of feed rate. I usually suggest starting with 0.012" depth per pass for harder plastics (acrylics) and 0.024" for woods. http://www.toolingpro.com/milling-calculator.php --- in addition to the typical calculations, includes horsepower calculations. I have been making my feeds and speeds with the help of GWizard with some success while I learn to CNC 6061 aluminum. Start off using an RPM derived for the chip load for the material being cut (see charts).

I needed to cut a lens that will likely be sanded on both sides to increase the opacity. Depth 0.2mm Handle carefully due to its brittle nature. Primary consideration is how fast the flutes of the cutter move against the material. [39], http://www.routerforums.com/cnc-routing/32970-feeds-speeds-needed-red-oak.html, Metric: http://www.endmill.com/pages/training/spdfeed.html. 400 mm/min feed In traditional machining, you tend to start out with a block of material slightly oversize of the actual part. What max depth of cut do you do on those V-bits bits per pass? Carbide Create has two notable sets of feeds and speeds for the Shapeoko --- build 433 uses a chipload-based calculation, while 440 and later use a set of pre-calculated feeds and speeds which are intended to be quite conservative, so as to minimize problems. Various tools may be used to heat it[322]: CNCzone thread: http://www.cnczone.com/forums/hobby-discussion/26351-cnc-post210273.html#post210273. If you are making sawdust the speed/feeds are to high. Dewalt set on 5, 6061 (1' x 1/2"), 1/4 x 4flt coated ball. High density polyurethane foams are often used in sign-making, as well as for props. [172], 3 or 5 in/min and a plunge depth of 0.05"[173]. Brand new HSS cutters are a good option. You can go back and do a 'finishing pass' just a hair deeper at slower speed to clean it up. Re: Vote for your favorite ShapeOko spindle solution! 5mm diameter tool blank.[155]. DWP611 speed at 1. spindle speed constant at 10000rpm. Yeah, the fifth pass is basically to exchange machine time for hand sanding time. 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.

When engraving plastics, coating the surface w/ WD-40 may allow easier removal of waste material which sticks at the cut edges: Re: Engraving plastics, https://www.reddit.com/r/CNC/comments/44xkqo/cutting_plastic_material_and_rates_to_use/, https://www.reddit.com/r/CNC/comments/765948/cheapest_machinable_plastic/. RPM: This makes nice long dagger shaped chips, and seems to cause the least chatter of all while still keeping a .5in^3/min material removal rate. Of the two I think I prefer bore, since it's quicker to set up and quicker to cut. This post should give you a head start. You can't choose an optimal depth and adjust the width to compensate as normal. [139], http://www.shapeoko.com/forum/viewtopic.php?f=5&t=6134&start=10#p51513, Aluminum spindle mounts for Makita RT0701c. Endmill selection can be critical for successful cutting. I'll never do that again though, but it was cool to see the machine pushed to its limits. It's hard to answer this in a simple blog post. For smaller details, I use a 20 degree tapered end mill, with a .004 tip. If cutting under 50% diameter you need to use a chip thinning calculator to see actual chip size. Machines similarly to hardwoods, a climb cut finishing pass may eliminate marks from chatter. May 2020 See Guesstimating Feed Rates for a technique for using these numbers to derive a first approximation for cutting a softer or harder wood which one has numbers for. [49]. |Carbide Create. Notes from IC for cutting his dust shoe: Makita RT0701 16in/min feed, 0.08" step down[215] at speed 2 (~12,280 r.p.m. Smooth surface. DOC - 10mm Suited for use in bearings and wear applications (it was originally developed as a replacement to the plectrums in harpsichords). I don’t mean buy a foot thick slab and try to mill it down to what you need. 16000 A horizontal roughing cut was done at 80IPM with a 0.25in, 0.060 corner radius end mill from lakeshore carbide (where I buy all my tools). You want to see discernible chips, even if they are small. [36]. 3-4 IPM 0.015 cut depth at the low end of the DW611's speed range with lubricant --- Copper sign, Ascertain that if a copper alloy, it does not contain beryllium. Onefinity CNC Router Examples: Example 1: Figure out proper Feeds and Speeds to cut walnut plaques. It was smoking quite a bit but the machine was marching along without missing steps or jerking. 1/8 inch depth per pass. SO3: http://www.shapeoko.com/forum/viewtopic.php?f=7&t=166&p=57325, 160 ipm. 0.063" straight 3-flute bit[159] 1000mmpm [145]. The thing that made the biggest difference to the finish was blasting all the chips out with air at regular intervals. Nick Offerman has an excellent guideline --- if working with any sort of rare/expensive wood the project should be expected to last at least as long as it took the tree to grow --- it's reprehensible to my mind to make some trivial, ephemeral thing out of a tropical hardwood. You can implement various strategies to do that when cutting parts out of a sheet or panel, but it really doesn't make any sense in that context because it's much less efficient from a cycle time perspective. One tactic is to use a down-cut spiral bit for the first half of the cut, then switch to an upspiral --- this may be of use w/ other forms of plywood. 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. 1.000 in Feed 5in (127mm)/min Faster feed rates prevent the bit from staying in one place for too long, which is a factor in overheating. Using a 1/4" 4 flute carbide from Kodiak (AlTiN coated). This will bring your work surface exactly square with the machine. It is why steel and to a lesser degree certain non-ferrous alloys are so difficult to cut. Wearing a dust mask is certainly not a bad idea, and is recommended. I run about 550mm/sec .5mm DOC and stepover. When milling plastics you want "chips" to come off the bit. What speed and feed should you run your bits at. 1/2" hdpe in 4 passes." If you find that you are instead getting "threads" of material you need to either increase your speed or increase your depth (preferably not both). 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]). I used some silicone spray initially, but I ran out and cut most of the job dry, periodically vacuuming chips out of the cut. ios iphone-app cad cam [147], 30 ipm, 10 plunge, .015 depth of cut, .2 step over.[149]. A faster plunge rate may help. Note that what is sold as 0.25" thick acrylic is typically manufactured to metric 6mm (0.236").
