You can alternatively choose to override it with a given feedrate value (and see what this does to chipload displayed below). @Hooby on the forum consolidated a nice list of Janka hardness values for many types of wood, which I include here for reference. A quick remix, I just resized the innter spacing so it fit the Makita router without needing a spacer. Rendered by PID 15286 on r2-app-06f60b283ae698777 at 2021-01-08 00:28:49.102709+00:00 running 27ea799 country code: GB. Higher speed is obtained when the dial is turned in the direction of number 6. Yes, provided you run the appropriate type of endmill, at the appropriate feeds and speeds, and the correct depth of cut. Multiple cutting passes at depth of cut d will be required to cut down to a total pocket depth of D: DOC is just as important as feeds & speeds to achieve a good cut, yet surprisingly there is much less information about how to determine its value, compared to the abundance of feeds and speeds charts. This basic worksheet will just compute the required feedrate to get the desired chipload (taking chip thinning into account). One could compute specific plunge rate and RPM based on the specific geometry of the tip of the endmill, but in practice it's easier to just: use the same RPM as for radial cuts. of the endmill that will be engaged in the material, a.k.a. Additional performance features include electronic speed control to maintain constant speed under load, and soft start feature for smooth start-ups. All of the info above only focused on the feeds and speeds for the radial part of the cut, but when the endmill is plunging (straight down/vertically), things are quite different: (obviously) the cutting edges on the circumference of the endmill are not cutting anything anymore, the cutting happens at the tip of the endmill only, like a drillbit. Not that you will ever need to use it, but for the math-inclined among you, here's the equation to compute TEA from stepover value: While we are talking about TEA, let's take a look at what happens when cutting a square pocket at 50% tool engagement (90° TEA) and reaching a corner: Just before moving into the corner, the tool engagement angle is 90°: But while cutting the corner, the TEA momentarily goes up to 180°: before going down to 90° again. for a given feedrate and RPM, an endmill with more flutes will cut thinner chips. The figures above provide a ballpark for DOC and WOC, taking into account two specific cases: slotting, and corners. for the material being cut (there's a list in a separate tab of the worksheet) and update it here. You have really dial in your speeds and feed rates. In the sketch below, imagine the blue triangle represents one cutting edge of the endmill. cutter. "Speeds" is the rotation speed of the endmill, i.e. 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 would have been if the cutter were engaged at 50%: The formula to determine this higher, adjusted target chipload is: For basic toolpaths, the stepover is often in the 40% to 50% range, and then you can just ignore chip thinning altogether. 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. The Shapeoko XXL supports the Dewalt DWP611 trim router and the Makita RT0701c trim router. The RT0701CX3 has a powerful 1-1/4 HP (maximum horsepower) motor with a variable speed control dial (10,000-30,000 RPM) that enables the user to match the speed to the application. Then...experiment. This way, climb and its many advantages is used for most of the cut, and the possible deflections happening during this roughing pass will be taken care of by the light conventional finishing pass (where the drawbacks of conventional will be irrelevant, since this finishing pass puts such low efforts on the machine anyway, and chip evacuation is not a problem either). Depth Per Pass, is how deep into the material the endmill will cut, along the Z axis. "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 also want the lower RPM for cutting metals like aluminum. This results in an ugly sound, a poor finish with marks/dents/ripples on the surface, and a reduced tool life. "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. I like it because of the lower RPM range. chipload value to avoid rubbing, there is a large consensus in the CNC community that a value of. In extreme cases, the endmill color itself may change to a dark shade. This will help you to … 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. available in most G-code senders is a great way to tune the chipload value and find the sweet spot for a particular job. How hard would it have been to introduce a setting in CC to select Shapeoko vs Nomad?). And then. The reason is probably that while there are mathematical recipes to choose feedrate and RPM for a given endmill geometry, the achievable DOC is much more tightly linked to the specific machine you are using, and specifically its rigidity and power. Deep slotting is notorious for causing issues when chips cannot be evacuated quickly enough. At the time of writing, Carbide Create did not have this feature, so it generated all toolpaths using conventional milling. This boils down to optimizing the cut parameters used throughout the job specifically for these very short times when the corners are being cut, which is not very efficient. 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. Have not used the lower speed settings, I seem to like the way it cuts on 4 and 5 with my 1/4 and 1/2 wide bits. The maximum thickness (noted "C" below) happens when the cutting edge exits the material. Either way, the feedrate to be used will be displayed at the right end of this line. the Tool Engagement Angle (. push the endmill away from the material: moderate deflection will affect accuracy (pieces will cut slightly larger or smaller than expected), excessive deflection will cause tool wear or even tool breakage. 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. ", and then determine the associated feedrate to get the right chipload. My Shapeoko XXL came with a Makita trim router as its spindle. "Climb" milling is when the direction of the endmill movement is such that the cutting edges bite from the outside to the inside of the material. NOTE: For other spindle options, and more information about the spindle mount, see the support page. aluminum mounts; 3D-printed Dust Shoe for the Makita RT0700C Router This section includes a little math (nothing too fancy), but not to worry: while it is important to understand the. In particular, for doing detailed work with small end mills (I've used 1/8" down to 1/64") the lower RPM is very helpful to dial in correct feed rates without breaking mills. 25% of 50% of 1/4'' = 0.03125'', so adjusted chipload is: The ideal setting would be to max out the RPM, say 24,000 (to take an example that is reachable on the Makita, DeWalt, and common spindles). of the diameter of the endmill for roughing, possibly even less for the hardest materials (, If you go for narrow and deep (and you should! 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. However, it requires specific toolpath strategies (e.g. : 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. This allows the ideal speed to be selected for optimum Note: This item is non-returnable. If you go for narrow and deep (and you should! ), given the small WOC values you will definitely need to take chip thinning into account. To keep this guideline table simple, I chose to only divide woods into "soft" and "hard" categories, and this labeling is not the correct definition either (which relates to whether the tree, have a hard or soft shell). Before diving into the relation between feedrate, RPM, and the other parameters, let's check how the tool cuts into the material. Somewhere on the internet I read about using an ER11 Colet as an adapter. Now we have to take a little detour and talk about stepover, because it impacts the effective chipload. Notice how I carefully avoided the case of V-bits throughout this section ? Plunge rate is mostly irrelevant for such shallow passes, any value will do. " : 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). , 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). Can be guided easily with one hand, very stable, and reasonably quiet (or at least quieter than my old Craftsman routers were). ", and this is the cornerstone of feeds and speeds. High RPMs induce lower cutting forces and generally provide better finish quality, but will also require higher associated feedrates to maintain a correct chipload: feeding faster can be a little scary at first, and leaves less time to react should anything go wrong. If the toolpath uses some ramping at an angle into the material, they can be increased quite a bit. Speed adjusting dial 1 011835 The tool speed can be changed by turning the speed adjusting dial to a given number setting from 1 to 6. Since its introduction, the Makita® GV5000 Sander has become one of the preferred tools for marble polishing applications. '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). The whole "feeds & speeds" topic is arguably the most daunting part of learning CNC. to reach the target chipload will be computed. It delivers speed, power, and precision in a handy and easy-to-use package. 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. This is a very popular approach when cutting metals on the Shapeoko, but its benefits apply to other materials too. 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. surface finish, dimensional accuracy). determine the required feedrate for this RPM to achieve the adjusted target chipload. is the rotation speed of the endmill, i.e. check that cutting force is within the machine's limits. The effective cutting diameter varies depending on how deep the V-bit goes. 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. of the feedrate for plastics (plunging fast is required to avoid melting), So when all is said and done, climb milling wins on almost every aspect except deflection. In practice, the latter is done. select WOC and DOC (depending on your machining style). The Shapeoko is partially assembled. 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). The associated required feedrate was therefore 0.002'' × 2 flutes × 25,000 RPM = 100ipm The cut produced equally good chips, However, that's true for even industrial grade machines. Axial Depth of Cut (ADOC) a.k.a. A rule of thumb is therefore to set RPM to "the maximum value you can tolerate and feel comfortable using", and then determine the associated feedrate to get the right chipload. While the principles decribed above apply, when doing a surfacing operation using either a surfacing bit (a.k.a. 12,000RPM and 108ipm, at the expense of higher cutting forces (which or may not be a problem, see power analysis section later below). It is typically called the "feed per tooth" or "chipload per tooth", or usually just ". So when all is said and done, climb milling wins on almost every aspect except deflection. and join one of thousands of communities. Use of this site constitutes acceptance of our User Agreement and Privacy Policy. The resulting chip (in green) has a similar shape to that in conventional milling, and again the max thickness of the chip is the chipload. reachable chipload depends on a lot of things, but mostly: (smaller teeth need to take smaller bites: the maximum chipload for a given endmill scales linearly with its diameter), used (how wide/deep the cutter is engaged) and the. the feeds & speeds for a particular situation, and to see the effects of any parameter change on the rest of them. Fly cutter) or any large square endmill, the intent is usually to shave off just a thin layer of material off the top surface, so one can feed quite fast. First step was to … RPM value. the MLCS Rocky 30 (see https://www.shapeoko.com/wiki/index.php/RT0701 ). You also need to make sure your machine is as square as possible. The Makita RP0900K 1¼ HP Plunge Router is the best woodworking router to buy if you want to do small to medium-sized jobs. List here: https://www.shapeoko.com/wiki/index.php/Spindle_Overview#Rotary_Spindle_Options. New Shapeoko 3 XXL Owner (Workflow Question). For the "wide and shallow" cut scenario (large WOC, small DOC), I like to start in this ballpark: 5% to 10% of the endmill diameter for metals e.g. The real value of calculators is in. Since the feedrate/RPM combination is derived from the desired chipload value, let's first have a look at what the range of acceptable chipload values is for the Shapeoko. check deflection value to make sure there is no risk of breaking the tool, and to optimize dimensional accuracy and finish quality. And then depth of cut will also come in the picture (more on this later). depth and width of cut), so "feeds and speeds" is often short for "all the cutting parameters". It’s almost identical to the Makita 1-1/4inch router, which Carbide previously used with their Shapeoko machines before replacing it with their own version. This kit includes: .25" Precision Collet .125" Precision Collet These are made in the US for Carbide 3D. climb milling used to have a bad reputation for being dangerous to use on machines with a lot of backlash. value to make sure there is no risk of breaking the tool, and to optimize dimensional accuracy and finish quality. If you run it at too fast a feed rate with too slow RPMs, and you break the mill off due to excessive deflection. Axial Depth of Cut (ADOC) a.k.a. There is a strong dependency between DOC and WOC: since cutting forces increase with both DOC and WOC, you cannot cut very deep while using a very large stepover, that would put too much effort on the endmill. Shapeoko comes with an industrial-grade motion controller running GRBL firmware, homing switches, and 4 NEMA 23 stepper motors. 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. section, that goes hand in hand with high DOC and small WOC. 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. At this stage, the material is known, the endmill geometry is known, chip thinning is accounted for, which gave us an adjusted target minimal chipload. how long it takes to complete the cut). 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. The interesting thing about the MRR figure is that it allows one to. for both power tools are completely interchangeable. 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. 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). @Hooby on the forum consolidated a nice list of Janka hardness values for many types of wood, which I include here for reference. If you still feel overwhelmed or don't care about optimizing power, force and deflection, I derived a more basic version: fill-in the number of flutes and diameter of your endmill, pick a target chipload value from the guideline table on the right, select WOC and DOC based on the recommanded values on the right (derived from the selected endmill diameter). The Shapeoko is not as rigid nor as powerful as pro CNC machines, so DOC recommendations for these machines need to be dialed back, even when using perfect feeds and speeds. the cutting parameters to achieve the desired result. to compare the efficiency of various cutting parameters. The most common signs of inadequate feeds and speeds are: sound, and specifically chatter: 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). For a given chipload, some combinations are still better than other mathematically-equivalent ones though (more on this below). 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. This is assuming you are using a sharp cutter. It looks like a fine piece of kit (as our UK cousins might say) and I look forward to trying it. Provide your own or buy one from us. Trying to solve a static issue with dust collection. of cut will also come in the picture (more on this later). Consider the following sketch of a side view showing multiple passes: Due to the geometry of the endmill tip, scallops of residual material will be left at regular intervals on the bottom surface. Increasing your feed rate decreases the speed difference between the edge of your tooling and the material, reducing friction. Climb milling, since it cuts chips from thick-to-thin, does not have this problem. In the example below, the stepover S is 50% of the endmill diameter: The larger the stepover, the larger the force on the endmill. 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). Higher chiploads are definitely possible (but may not be desirable). depth and width of cut), so "feeds and speeds" is often short for "all the cutting parameters". RPM range is 12,000 - 30,000 Note: The Compact Router is only available in 120V with a standard US plug. In practice, feedrates above 200ipm are used for rapids only, there are very little usecases where actually cutting at higher than 200ipm would be useful. 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. Makita Spindle. scale that measures that. 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. This features captured nut pockets so you can use locknuts to hold the router securely as well as set of nut plates so you don't have to take apart the Z axis to remove the brackets. in conventional milling, the cutter flutes move against the direction of the feedrate, so chips are more likely to be pushed to the front of the cut, leading to chip recutting which is bad for finish quality. A large chipload requires a lot of router torque and machine rigidity, and each endmill has recommended chipload limits from the manufacturer anyway (i.e. Our Precision Collet Set The Compact Router includes a 12 foot power cord to make wiring easier for everything from our Shapeoko 3 to the larger Shapeoko XXL. Bottom line, I think both are comparable in major ways: price, noise, warranty, replaceable points when they … And lower speed is obtained when it is turned in the direction of number 1. DeWalt or Makita for the Shapeoko 3? When using conventional milling, the force tends to be parallel to the stock: When using climb milling, the force tends to be perpendicular, i.e. I have attached a version here for convenience, but you may want to check if a more recent version is available on the forum. The recommended chipload/DOC values mentioned above include some margin to take this effect into account to some extent. We just posted our newest product, the Carbide Compact Router. In fact, the accessories (bases, dust collection, etc.) The Janka threshold for "hard" vs. "soft" is highly debatable, but a value of 1000 seems reasonable to steer the chipload selection. However, it requires specific toolpath strategies (, 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. But it is still a very common approach for pocketing and profile cuts on the Shapeoko, and it has simplicity going for it. increase tool life (i.e. and up to 30 in³/min for soft woods, MDF, ... Once you get this power value, you can compare it to your router's maximum output power. Slow your spindle (lower RPM) If your router or dremel has variable speeds, turn it down. So it does not quite make sense to be using a target chipload value for a V-bit. 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. See adaptive clearing and pocketing in the. The alternatives include avoiding straight corners in the design if possible (e.g. Since the endmill revolves at RPM turns per minute, in one minute a length of N × chipload × RPM will have been cut. as the maximum value you can tolerate and feel comfortable using. Shapeoko comes with an industrial-grade motion controller … Since the cutter does RPM revolutions per minute and each of them is 2×Pi radians: or in the Imperial units converting N⋅m to lbf⋅in (×8.85 factor) , since (60 × 8.85) / (2 × 3.14159) = 84.5: So all of this can be derived from the feedrate, WOC, DOC, endmill size, and material. Where chip thinning really matters is for adaptive clearing toolpaths, that typically use small stepovers (more on this in the, should be used for the case where there is no chip thinning, while the term. Printed & tested, fits great. 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. Some are merely replacements for the standard collets in different sizes, while at least one manufacturer offers specialized systems which allow one to use ER style collets. 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. Depth of Cut (DOC) a.k.a. ), the feeds and speeds are likely incorrect (too low or too high chipload), or the tool is dull and is rubbing rather than cutting. Whether or not you need 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. check that cutting power is within the router's limits. The remaining part is to chose a specific combination of RPM and feedrate values that together will produce this chipload, following the formula described earlier. The RPM range is 12,000 – 13,000RPM, making it pretty powerful. This section includes a little math (nothing too fancy), but not to worry: while it is important to understand the dependencies between the cutting parameters, calculators will take care of all those computations for you. Material is hard wood and endmill is a 3-flute 1/4'' => the chipload table recommends up to 0.002''. I'm not sure if my order will come with the Makita mounting ring, or if I'll have to order one separately. 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. Technically, the feedrate can go beyond 200ipm, if the associated GRBL limits parameters are set to a higher limit. 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.
