The Shapeoko XXL supports the Dewalt DWP611 trim router and the Makita RT0701c trim router. Since the endmill revolves at RPM turns per minute, in one minute a length of N × chipload × RPM will have been cut. © 2021 reddit inc. All rights reserved. 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. While the principles decribed above apply, when doing a surfacing operation using either a surfacing bit (a.k.a. Any mechanical mod of the machine also impacts the max chipload capability. The Elaire Corporation makes 3/8" and 1/8" precision collets for both routers, which makes using micro end mills much easier. ", and then determine the associated feedrate to get the right chipload. Provide your own or buy one from us. So very often, Carbide Create suggested values ended up being completely unpractical with a Shapeoko and Makita router (e.g. List here: https://www.shapeoko.com/wiki/index.php/Spindle_Overview#Rotary_Spindle_Options. The alternatives include avoiding straight corners in the design if possible (e.g. refer to my proposed guideline table, or roll your own. 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. So this is a Goldilocks situation: the chipload must be high enough to avoid rubbing and overheating of the endmill, and small enough to be within the torque/rigidity limits of the machine and the endmill's rated maximums. All three work well on Shapeoko. Axial Depth of Cut (ADOC) a.k.a. 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. Can be guided easily with one hand, very stable, and reasonably quiet (or at least quieter than my old Craftsman routers were). 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. Either way, the feedrate to be used will be displayed at the right end of this line. The effective cutting diameter varies depending on how deep the V-bit goes. 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). @Hooby on the forum consolidated a nice list of Janka hardness values for many types of wood, which I include here for reference. You can build it in about 2 hours. 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). "Speeds" is the rotation speed of the endmill, i.e. 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). Additional performance features include electronic speed control to maintain constant speed under load, and soft start feature for smooth start-ups. As a side note, for ball endmills, stepover value influences surface finish quite a lot. that will take a lot of very shallow bites at the corners instead of a deep one. I'm not sure if my order will come with the Makita mounting ring, or if I'll have to order one separately. 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. The main reason is that the traditional way to determine feeds and speeds (especially when cutting metal) is to start from the required. 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. And finally, even if the cutting power is within the range of your router, there is still the matter of the cutting force that the Shapeoko has to put on the endmill to move it through the material: In metric units, the torque is the force (in Newton) times the distance in meters (in this case the radius of the endmill), and power in Watts is torque times the angular velocity w, in radians per second. The figures above provide a ballpark for DOC and WOC, taking into account two specific cases: slotting, and corners. Then...experiment. For the "narrow and deep" cut scenario (small WOC, large DOC), I like to use these guidelines: possibly even less for the hardest materials (e.g., 4% for steel). Deep slotting is notorious for causing issues when chips cannot be evacuated quickly enough. While there is definitely a good amount of experience (and experimentation) involved in finding the perfect feeds and speeds for any given situation, there are a few underlying principles that are worth understanding for two reasons: to figure out reasonable values to start from, when a new situation shows up for which you cannot find any predefined recommended values. 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. You should never use a dull cutter anyway, if you do you may end up rubbing even at this 0.001'' chipload. However there are other factors at play: in conventional milling, the chip is cut from thin-to-thick, so by definition when the flute first comes in contact with the material, it is rubbing the surface a little before it starts actually cutting into the material. 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. With everything hooked up, it was time for the moment of truth. Get an ad-free experience with special benefits, and directly support Reddit. RPM values below 10.000RPM…so each time I had to use a higher RPM, I add to compensate feedrate accordingly, not very fun) (stepover) based on the machining style you want (large WOC and small DOC, or large DOC and small WOC). [–]tinkermakedotcom 2 points3 points4 points 3 years ago (4 children). Any mechanical mod of the machine also impacts the max chipload capability. (self.shapeoko), [–][deleted] 6 points7 points8 points 3 years ago (0 children), First off, this Winston Moy video will explain it far better than anything else I have seen: https://www.youtube.com/watch?v=5h8o2Id1iLE. The real value of calculators is in. Variable speed control dial (10,000-30,000 RPM) to match the speed to the application Smooth rack-and-pinion fine depth adjustment system for more precise settings Quick-release cam lock system for convenient depth adjustments and base removal/installation Accepts industry standard template guides @Hooby on the forum consolidated a nice list of Janka hardness values for many types of wood, which I include here for reference. (Surface Feet Per Minute): this is the linear speed of the edge of the cutter, and it should be within a certain range depending on the material and the endmill. The Shapeoko uses our Carbide Compact Router or you can provide your own DeWalt DWP-611 or Makita RT0701C as a spindle. Note that spindles may be upgraded w/ better collets. Would love a automatic tool changer for the Pro. Trying to solve a static issue with dust collection. for the same "thick-to-thin" reason, climb milling is a little more tolerant of less-than-perfectly-sharp endmills. between the cutting parameters, calculators will take care of all those computations for you. This is a very popular approach when cutting metals on the Shapeoko, but its benefits apply to other materials too. However, it requires specific toolpath strategies (e.g. The folks at Shapeoko recommend the DeWalt D26200 or Makita RT0700C to use with the machine. 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. of material. 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. 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. You can alternatively choose to override it with a given feedrate value (and see what this does to chipload displayed below), or to forget about chipload and use a given cutting force as the ultimate target. the MLCS Rocky 30 (see https://www.shapeoko.com/wiki/index.php/RT0701 ). Note: This version of the Shapeoko XXL does NOT include a trim router, this will need to be purchased separately. Each flute contributes in turn to removing material during one revolution of an endmill. 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! is the rotation speed of the endmill, i.e. See adaptive clearing and pocketing in the. More important than speed at the bit shank, though, is a bit's rim speed, the velocity of the cutter at the farthest point from the center of the shank. This kit includes: .25" Precision Collet .125" Precision Collet These are made in the US for Carbide 3D. 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). 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). For a given feedrate and RPM, the deeper it is the larger the forces on the endmill. 12,000RPM and 108ipm, at the expense of higher cutting forces (which or may not be a problem, see power analysis section later below). gmack's advanced feeds and speeds worksheet, 2019-08-11 Speeds and Feeds Workbook.xlsx, you chose (chip thinning will be taken into account automatically depending on WOC value), if you care about power/force analysis, look-up the. The required feedrate to reach the target chipload will be computed. ), given the small WOC values you will definitely need to take chip thinning into account. The RT0701C 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. the feeds & speeds for a particular situation, and to see the effects of any parameter change on the rest of them. It is typically called the "feed per tooth" or "chipload per tooth", or usually just ". Yes, but very slowly and with lots of patience. Use of this site constitutes acceptance of our User Agreement and Privacy Policy. 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. '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 large WOC, small DOC approach only ever uses the tip of the endmill, so that part will wear out quickly while the rest of the endmill length of cut remains unused. the Tool Engagement Angle (. "Feeds" and "Speeds" go hand in hand, what really matters is the combination of feedrate and RPM values for a given situation. Or, you can take a different approach and avoid slotting altogether, by using smarter toolpaths. Higher speed is obtained when the dial is turned in the direction of number 6. RPM value. The Makita and DeWalt routers are rated at a max of 1.25HP (932Watts), but that is. Do not take it for granted, start above 0.001'' and increase it incrementally (by keeping RPM constant and increasing feedrate) to find the limits for your machine and for a given material. 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. Increasing RPMs may help, but the best approach is to use a finish pass with very low WOC. See adaptive clearing and pocketing in the Toolpaths section! 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. 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. 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. ), the feeds and speeds are likely incorrect (too low or too high chipload), or the tool is dull and is rubbing rather than cutting. 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. 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. The associated required feedrate was therefore 0.002'' × 2 flutes × 25,000 RPM = 100ipm The cut produced equally good chips, It looks like a fine piece of kit (as our UK cousins might say) and I look forward to trying it. Let's say we decided to go for 16,000 RPM instead, the required feedrate would become: If going 144ipm still feels a little fast, it is possible to obtain the same chipload at lower RPM and lower feedrate, e.g. It's also called Width of Cut (WOC) or Radial Depth of Cut (RDOC). Anyone have experience with getting a tool changer working? The Janka threshold for "hard" vs. "soft" is highly debatable, but a value of 1000 seems reasonable to steer the chipload selection. This will help you to … Shapeoko comes with an industrial-grade motion controller … 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. And then depth of cut will also come in the picture (more on this later). Axial Depth of Cut (ADOC) a.k.a. 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. In practice, the latter is done. a little fast, it is possible to obtain the same chipload at lower RPM and lower feedrate, 12,000RPM and 108ipm, at the expense of higher cutting forces (which or may not be a problem, see power analysis section later below). The Makita router has a fairly wide speed range, a 1/4" collet, and a nice sturdy cylindrical body unlike the popular DeWalt DW660 drywall power tool. : it is quite easy to forget that the Shapeoko is not as rigid as industrial CNCs, so endmill manufacturers recommendations may not be directly suitable for the Shapeoko. round the corners...) or use an adaptive clearing toolpath that will take a lot of very shallow bites at the corners instead of a deep one. You also need to make sure your machine is as square as possible. use the following search parameters to narrow your results: ShapeOko is a Desktop CNC Router invented by Edward Ford. If we sketched N successive bites that the endmill takes into the material, it would look something like this: If the endmill has N flutes, one revolution will cut N chips, i.e. for a given feedrate and RPM, an endmill with more flutes will cut thinner chips. 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. Since its introduction, the Makita® GV5000 Sander has become one of the preferred tools for marble polishing applications. The required feedrate would then be : That is above the default capability of the Shapeoko (200ipm), it would be scarily fast for cutting hard wood, and 24,000 RPM may sound too loud to your taste anyway. there's always a limit to the size of the bite you can take, whether you're a squirrel or a white shark). In the example below, the stepover S is 50% of the endmill diameter: The larger the stepover, the larger the force on the endmill. 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. This results in an ugly sound, a poor finish with marks/dents/ripples on the surface, and a reduced tool life. if computed feedrate exceeds the Shapeoko limit, choose a lower RPM value and recompute feedrate. Carbide3D Compact Router for Shapeoko Features a trim router for use with CNC machines Includes a 12 ft power cord Offers 12,000 - 30,000 RPM Comes with 2 sets of replacement brushes NOT compatible with the Shapeoko Z-plus 69mm (RB-Crb-92/93/97) Now if you want to figure out how close you are to the absolute/physical. NOTE: For other spindle options, and more information about the spindle mount, see the support page. 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. feedrate values by any factor, and it will still provide the same chipload. : 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. Notice how I carefully avoided the case of V-bits throughout this section ? value (or alternatively SFM, then RPM will be derived from it). 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. This is a given when using a router where there is no dynamic control on the RPM anyway, so the same value is used throughout the cut. 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. 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 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). "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. It starts out very thin, and gradually increases in thickness. if you care about power/force analysis, look-up the K-factor for the material being cut (there's a list in a separate tab of the worksheet) and update it here. 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. " Depth Per Pass, is how deep into the material the endmill will cut, along the Z axis. 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 Elaire Corporation makes 3/8" and 1/8" precision collets for both routers, which makes using micro end mills much easier. The Shapeoko is made in the US and comes with a 12 month warranty. 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. check that cutting power is within the router's limits. Material is hard wood and endmill is a 3-flute 1/4'' => the chipload table recommends up to 0.002''. select WOC and DOC (depending on your machining style).
