Also air cooling is less at low RPM. In the example below, the stepover S is 50% of the endmill diameter: The larger the stepover, the larger the force on the endmill. The Shapeoko 3 XXL from Carbide 3D is a large CNC router kit that is easy to assemble and use, making it the choice for us. check deflection value to make sure there is no risk of breaking the tool, and to optimize dimensional accuracy and finish quality. This kit includes: .25" Precision Collet .125" Precision Collet These are made in the US for Carbide 3D. I mean it in the "wood hardness" way, and there is a useful. In so-called "conventional" milling, the direction of the endmill movement is such that the cutting edges bite from the inside to the outside of the material. The V-carving toolpaths tend to generate sloped trajectories and a lot of plunges and retracts, so the cutter engagement is constantly changing. But it is still a very common approach for pocketing and profile cuts on the Shapeoko, and it has simplicity going for it. The Toolpaths section will cover the notion of "roughing" versus "finishing" toolpaths, and that will then open the way for the best approach: using climb for roughing, then conventional for finishing. The real value of calculators is in optimizing the feeds & speeds for a particular situation, and to see the effects of any parameter change on the rest of them. Note: This version of the Shapeoko XXL does NOT include a trim router, this will need to be purchased separately. And then depth of cut will also come in the picture (more on this later). The solution is to artificially target a higher chipload value (all other parameters staying the same), such that the actual size of the chip is increased to approximately what it. The Shapeoko is made in the US and comes with a 12 month warranty. List here: https://www.shapeoko.com/wiki/index.php/Spindle_Overview#Rotary_Spindle_Options. to reach the target chipload will be computed. of material. Since the endmill revolves at RPM turns per minute, in one minute a length of N × chipload × RPM will have been cut. You can alternatively choose to override it with a given feedrate value (and see what this does to chipload displayed below). if one buys a matching nut for each collet) and afford a greater clamping tolerance (e.g., a 1/4" collet can hold a 6mm endmill[8]). If the computed feedrate turns red, it is beyond the limit of the Shapeoko, and you should select a lower RPM and/or use an endmill with a lower flute count. You also need to make sure your machine is as square as possible. is feedrate, on some CNCs with a fixed tool and moving plate this is the speed at which the material is fed into the cutter, on a Shapeoko this is the speed of the gantry pushing the cutter into the material. " Just like for slotting, this means that the feedrate and DOC cannot be as high as one would like, since they need to be dialed back a bit to manage corners. scale that measures that. making dust, instead of clearly formed chips is an indication that chipload is probably too low (MDF is an exception, you just cannot get chips anyway with this material). Axial Depth of Cut (ADOC) a.k.a. in climb milling, the router torque pushes in the same direction as the feedrate, while in conventional it fights against the feedrate, so the forces on the stepper motors are higher. the Tool Engagement Angle (TEA), will be different: For a 50% stepover, the TEA will be 90°: For a smaller stepover, say 25%, the TEA will be reduced (in this case to 60°): Slotting is a different story: half of the endmill is engaged at all times, so the TEA is 180°: The force on the endmill will be much higher than when cutting at 90° TEA, so the max achievable chipload/DOC combination for a given machine/endmill/material is lower. Makita Spindle. In theory, there are two options: selecting a feedrate value and solving for the associated required RPM value, or selecting an RPM value and solving for the associated feedrate. Axial Depth of Cut (ADOC) a.k.a. avoid/minimize chatter (the horrendous sound heard when the endmill/machine vibrates while cutting through the material), optimize material removal rate (e.g. Also, check out. While predefined recommendations for common endmills and materials are very useful, at some point it becomes impossible to produce feeds & speeds charts for every possible combination of factors, and also very tedious to compute everything manually. In the sketch below, imagine the blue triangle represents one cutting edge of the endmill. This results in an ugly sound, a poor finish with marks/dents/ripples on the surface, and a reduced tool life. This being said, your CAM tool may or may not give you the option to select the milling direction (climb or conventional). You should never use a dull cutter anyway, if you do you may end up rubbing even at this 0.001'' chipload. Additional performance features include electronic speed control to maintain constant speed under load, and soft start feature for smooth start-ups. The Carbide Compact Router has a diameter of 65mm and a speed range of 12k-30k RPM. In practice, the latter is done. The numbers here are with the router running without a load. But it is still a very common approach for pocketing and profile cuts on the Shapeoko, and it has simplicity going for it. refer to my proposed guideline table, or roll your own. Then...experiment. In order to meet the demand for a hook and loop backed pad that is designed specifically for this tool, we introduced the Alpha® GV Backer Pad. And the distance being cut per minute is exactly the definition of feedrate, therefore Feedrate = N × RPM × Chipload, which also means: for a given endmill and RPM, the faster the feedrate the larger the chipload. value to make sure there is no risk of breaking the tool, and to optimize dimensional accuracy and finish quality. will be required to cut down to a total pocket depth of, approach is much preferable, as it spreads the heat and tool wear much more evenly along the length of the endmill. BUT endmills are really not optimized for drilling, so their ability to plunge efficiently through material is quite limited. ", and then determine the associated feedrate to get the right chipload. Notice how I carefully avoided the case of V-bits throughout this section ? Any mechanical mod of the machine also impacts the max chipload capability. You also want the lower RPM for cutting metals like aluminum. The direction of the cut (climb versus conventional milling) pertains to the toolpath's generation options and not directly to the feeds and speeds, but while we are on this topic: since tool deflection is mainly perpendicular to the cut when using climb milling, it would seem like it is better to use conventional milling, to keep deflection parallel to the cut and therefore minimize dimensional errors on the final piece. If you use the wrong end mill at too fast an RPM with too slow of a feed rate, and you get melted aluminum binding up on the end mill. And the distance being cut per minute is exactly the definition of feedrate, therefore, This also means that if your CAM tool comes up with feedrates or RPMs that are not in the range of your machine's abilities (, , recommended RPM lower than the minimum RPM of your router), you can just scale both RPM. What would I be getting myself into? Alternately it is also possible to lower the feedrate by targetting a smaller chipload while ensuring it is still at least at the minimum recommended value of 0.001'', and assuming you are using a sharp enough cutter: To get a 0.001'' effective target chipload, the adjusted target chipload would become 0.0015'', the feedrate would then be 0.0015 × 3 × 16,000 = 72ipm. from, when a new situation shows up for which you cannot find any predefined recommended values. The Carbide 3D is supposed to be a copy of the Makita but while you can use the same collets and it is the same size, it has differences like the speed is from 12k to 30K while the Makita is from 10K to 30K so there is an advantage to the Makita as some jobs require that you run the router at low speed. Each flute contributes in turn to removing material during one revolution of an endmill. Note: This item is non-returnable. I have attached a version here for convenience, but you may want to check if a more recent version is available on the forum. At 25,000 RPM (near the max of the Makita router RPM range) for a 1/4'' endmill in acrylic, the recommended chipload range is 0.001''–0.005'', I went for 0.002'' to have a little margin above the 0.001'' minimum. ), given the small WOC values you will definitely need to take chip thinning into account. Additional performance features include electronic speed control to maintain constant speed under load, and soft start feature for smooth start-ups. And this cutting force can then be compared with the Shapeoko's limit estimated (experimentally) to be around 20 lbf (9Kg). increase tool life (i.e. The Shapeoko's limits must also be accounted for: the absolute maximum theoretical chipload on a stock Shapeoko would be reached when using a single-flute endmill at the lowest RPM (10,000RPM on the Makita router) and at the fastest feedrate of 200 inch per minute, and that would be 200/(1×10,000) = 0.02'' = 0.5mm. The other side effect of slotting is that chip evacuation is not as good: the flutes are in the air only 50% of the time, so the chips that form inside them have less time/fewer opportunities to fly away. The real value of calculators is in. 12,000RPM and 108ipm, at the expense of higher cutting forces (which or may not be a problem, see power analysis section later below). [7] These are more convenient and easier to change (esp. If the blue cross is the position of the center of the endmill when this cutting edge starts biting into the material, and if the endmill is moving into the material at feedrate F, then a little bit later the endmill center is at the position of the purple cross, and the cutting tooth has rotated and gone out of the material. Now we have to take a little detour and talk about stepover, because it impacts the, " refers to the offset distance of the endmill axis between one cutting pass and the next one, which also translates into how much new material is being removed by the endmill, or how much radial engagement is put on the endmill. This results in an ugly sound, a poor finish with marks/dents/ripples on the surface, and a reduced tool life. select target RPM value (or alternatively SFM, then RPM will be derived from it). These will be more or less visible depending on how well the material can hold small details (a 20% to 33% stepover should be small enough for wood, while it could need to be lowered down to 10% stepover for metal). This will help you to … RPM values below 10.000RPM…so each time I had to use a higher RPM, I add to compensate feedrate accordingly, not very fun) "Speeds" is the rotation speed of the endmill, i.e. New Shapeoko 3 XXL Owner (Workflow Question). Actually, they are also somewhat coupled with a number of other parameters (. So this is yet another parameter to watch out for when selecting feeds and speeds and DOC/WOC values, especially when using small diameter endmills. Before diving into the relation between feedrate, RPM, and the other parameters, let's check how the tool cuts into the material. A number of calculators have been implemented to address this, ranging from free Excel spreadsheets that basically implement the equations mentioned above, to full-fledged commercial software that embed material/tool databases, the most famous one probably being, a feeds & speeds calculator is debatable: most people use a limited number of combinations of material/endmill sizes anyway, in which case relying on a few good recipes for your machine is enough. You will need to feed faster, and/or use an endmill with a lower flute count. The main reason is that the traditional way to determine feeds and speeds (especially when cutting metal) is to start from the required. The maximum reachable chipload depends on a lot of things, but mostly: the type and diameter of the endmill (smaller teeth need to take smaller bites: the maximum chipload for a given endmill scales linearly with its diameter). ", and this is the cornerstone of feeds and speeds. For most hobby CNC routers the cutting forces are light and the low RPM/cooling factor is neglible. A proposed workflow to determine a reasonable starting point for feeds and speeds and DOCs on the Shapeoko for a given project that uses a specific material and endmill, is: select a target chipload in the recommended chipload range for this material+endmill combination. If the toolpath uses some ramping at an angle into the material, they can be increased quite a bit. power, and the power efficiency of a router is not very good (~50%), so the max actual power at the cutter is more likely around 450W. Now if you want to figure out how close you are to the absolute/physical. Makita RT701C RPM testing Upgrades I'm looking into the Makita RT701C as an upgrade to my machine and I did some testing to see how it performs right out of the box. The alternatives include avoiding straight corners in the design if possible (e.g. Can someone measure the overall XXL height for me please? depth and width of cut), so "feeds and speeds" is often short for "all the cutting parameters". Aim for the low end of the range, to reduce cutting force. Rendered by PID 15286 on r2-app-06f60b283ae698777 at 2021-01-08 00:28:49.102709+00:00 running 27ea799 country code: GB. ), the feeds and speeds are likely incorrect (too low or too high chipload), or the tool is dull and is rubbing rather than cutting. If we wanted to be pedantic, the term chipload should be used for the case where there is no chip thinning, while the term chip thickness should be used to name the adjusted/effective chipload after chip thinning is taken into account. How hard would it have been to introduce a setting in CC to select Shapeoko vs Nomad?). Material is hard wood and endmill is a 3-flute 1/4'' => the chipload table recommends up to 0.002''. If you need to optimize cutting time for a given piece, you will also need to take a look at the material removal rate (MRR): This yields a value in cubic inches (or cubic millimeters) of material removed per minute, and therefore relates to how fast you can complete a job. is the rotation speed of the endmill, i.e. If you run it at too fast a feed rate with too slow RPMs, and you break the mill off due to excessive deflection. The associated required feedrate was therefore 0.002'' × 2 flutes × 25,000 RPM = 100ipm The cut produced equally good chips, Endmills are not infinitely rigid, they tend to bend (deflect) when submitted to the cutting forces, and that deflection needs to be taken into account in the feeds and speeds. For example, a 1⁄2 "-diameter bit spinning at 10,000 rpm … Cutting passes with a small stepover are better for surface finish quality, while passes with large stepover obviously reduce overall cutting time since fewer passes are required to cut a given amount of material. The alternatives include avoiding straight corners in the design if possible (. value (or alternatively SFM, then RPM will be derived from it). Depth Per Pass, is how deep into the material the endmill will cut, along the Z axis. However, it requires specific toolpath strategies (e.g. (stepover) based on the machining style you want (large WOC and small DOC, or large DOC and small WOC). You also want the lower RPM for cutting metals like aluminum. : even without chatter, a poor surface finish can indicate that the final cutting pass was too agressive (too much chipload or too much deflection). The Makita edges out the Dewalt for the lower RPM range. there's always a limit to the size of the bite you can take, whether you're a squirrel or a white shark). Say we use a 25% radial depth of cut / stepover, i.e. So when all is said and done, climb milling wins on almost every aspect except deflection. select WOC and DOC (depending on your machining style). Bottomline: slotting is hard on the machine, so you may have to: limit DOC to the low end of the range of values, optimize chip evacuation by using an endmill with a lower number of flutes, and/or a good dust shoe or blast of air. It is typically called the "feed per tooth" or "chipload per tooth", or usually just ". (DOC) a.k.a. "Feeds" is feedrate, on some CNCs with a fixed tool and moving plate this is the speed at which the material is fed into the cutter, on a Shapeoko this is the speed of the gantry pushing the cutter into the material. You can then check the analysis of deflection, cutting force, and power in the lower part of the worksheet. Unlike chiploads that NEED to be in a specific range to get good cuts, the situation is easier for DOC and WOC: you can just start with small, conservative values and then increase them to find the limit for your machine/endmill/material combination. For a given chipload, some combinations are still better than other mathematically-equivalent ones though (more on this below). Yes, but very slowly and with lots of patience. melted material: especially in plastics and soft metals like aluminium, if the feedrate is too low for the selected RPM, the friction will cause the material to melt rather than shear, the tool flutes will start filling with melting material, and this usually ends up with tool breakage. a length of N × chipload of material. have been if the cutter were engaged at 50%: For basic toolpaths, the stepover is often in the 40% to 50% range, and then you can just ignore chip thinning altogether. This temporary rubbing amounts to heat, so in the long run a conventional cut produces more heat, leading to faster tool wear. chip is smaller, its maximum thickness is smaller than targeted, so there is again a risk of rubbing, or at least of sub-optimal heat removal. I got a desktop CNC router from Carbide 3D a shapeoko XL, with it came a few American sized router bits that won't fit the regular European Makita or Dewalt routers without an adapter. The Makita XTR01Z 18V LXT Brushless Compact Router is essentially the cordless version of the Makita RT0701CX3 1-1/4 hp compact router, except it has a brushless motor. Since the endmill revolves at, turns per minute, in one minute a length of, will have been cut. Where chip thinning really matters is for adaptive clearing toolpaths, that typically use small stepovers (more on this in the Toolpaths section). "Feeds" and "Speeds" go hand in hand, what really matters is the combination of feedrate and RPM values for a given situation. Experimentation is king in V-carving, but a common starting point for using V-bits in wood is as follows: Feedrate in the 30–60 ipm range (lower for hard wood, faster for soft wood), If your CAM software supports it, you may want to use a roughing pass and a finishing pass (with more aggressive settings for the roughing pass to spare time, and more conservative settings for the finishing pass). surface finish, dimensional accuracy). and join one of thousands of communities. My Shapeoko XXL came with a Makita trim router as its spindle. for the same "thick-to-thin" reason, climb milling is a little more tolerant of less-than-perfectly-sharp endmills. Depth of Cut (DOC) a.k.a. Either way, the feedrate to be used will be displayed at the right end of this line. "Stepover" refers to the offset distance of the endmill axis between one cutting pass and the next one, which also translates into how much new material is being removed by the endmill, or how much radial engagement is put on the endmill. In fact, the accessories (bases, dust collection, etc.) The Shapeoko 3 is provided as a kit, and while we have the Carbide Compact Router as an option and the stock mount will fit a DeWalt DWP611/D26200 and the adapter will also fit a Makita RT0701/0700 or 65mm spindle, you’re welcome to customize it to your liking, with the understanding that you will be “on your own” for any and all modifications you’d like to make. It looks like a fine piece of kit (as our UK cousins might say) and I look forward to trying it. : when feeds and speeds are not right for a given material/endmill/DOC/WOC, the tool tends to vibrate, and this vibration can get worse if there is resonance with another source of periodic variation elsewhere in the system (most often: the router and its RPM). The RPM range is 12,000 – 13,000RPM, making it pretty powerful. [–]tinkermakedotcom 2 points3 points4 points 3 years ago (4 children). Cutting passes with a small stepover are better for surface finish quality, while passes with large stepover obviously reduce overall cutting time since fewer passes are required to cut a given amount of material. Additional performance features include electronic speed control to maintain constant speed under load, and soft start feature for smooth start-ups. First step was to … I mean it in the "wood hardness" way, and there is a useful Janka scale that measures that. GRBL has some limitations on feed, especially in smaller parts and curves, so this is not always possible. Depth Per Pass, is how deep into the material the endmill will cut, along the Z axis. The realtime feedrate override available in most G-code senders is a great way to tune the chipload value and find the sweet spot for a particular job. finish quality: even without chatter, a poor surface finish can indicate that the final cutting pass was too agressive (too much chipload or too much deflection). to initially clear material down to the required depth, to allow small WOC to be used for the rest of the cut), this is covered in the Toolpaths section. fill-in the specs of the selected endmill, and the target chipload value you chose (chip thinning will be taken into account automatically depending on WOC value). climb milling used to have a bad reputation for being dangerous to use on machines with a lot of backlash. There is always a compromise to be found between going faster but with a lower tool engagement (low DOC and/or low WOC), or going slower but with a higher tool engagement (higher DOC or high WOC), while staying within the bounds of what the machine can do. For the minimum chipload value to avoid rubbing, there is a large consensus in the CNC community that a value of 0.001'' (0.0254mm) is a good absolute lower limit guideline, at least for 1/4'' endmills and larger. 's worksheet is available in the forum here: https://community.carbide3d.com/t/speeds-feeds-power-and-force-sfpf-calculator/16237, value from the guideline table on the right, based on the recommanded values on the right (derived from the selected endmill diameter). if computed feedrate exceeds the Shapeoko limit, choose a lower RPM value and recompute feedrate. [–]TheKLaMike[S] 1 point2 points3 points 3 years ago (3 children), [–]WillAdams 1 point2 points3 points 3 years ago (0 children), https://www.youtube.com/watch?v=NfYc35KeTEY, (from https://www.shapeoko.com/wiki/index.php/Shapeoko_3#Videos ), c.f., https://www.shapeoko.com/wiki/index.php/Materials#Aluminium, [–][deleted] 1 point2 points3 points 3 years ago (0 children). Would love a automatic tool changer for the Pro. If you go for narrow and deep (and you should! The required feedrate to reach the target chipload will be computed. It is typically called the "feed per tooth" or "chipload per tooth", or usually just "chipload", and this is the cornerstone of feeds and speeds. I ended up going with a Makita (personal preference over the Dewalt) just because I couldn't find any reviews/experience anyone had with the new router. The interesting thing about the MRR figure is that it allows one to compare different combinations, and figure out which one is the most efficient (time-wise). DXF files for Makita rc0701c projects and enclosure; Mount for a Makita RT0701--- includes design process for a mount which includes a dust shoe (.svg source). : especially in plastics and soft metals like aluminium, if the feedrate is too low for the selected RPM, the friction will cause the material to melt rather than shear, the tool flutes will start filling with melting material, and this usually ends up with tool breakage. The Makita and DeWalt routers are rated at a max of 1.25HP (932Watts), but that is input power, and the power efficiency of a router is not very good (~50%), so the max actual power at the cutter is more likely around 450W. Any mechanical mod of the machine also impacts the max chipload capability. A too small chipload is actually worse: since the cutting edges are not infinitely sharp, at some point instead of slicing into the material, the cutting edges will mostly rub against the surface, and then "heat happens" and this is very bad for the quality of the cut and for tool life. if stepover is less than 50%, adjust target chipload for chip thinning. 4 children ) to faster tool wear made in the direction of number 6 some margin to take a detour...
