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. Adobe InDesign CS6 (Windows) The Carbide ER-11 Compact Router is our custom-made trim router packaged for use with any of our CNC routers. Software: Be sure the machine comes with all the CNC software you need. . Router Bit, 1/2" Shank, 1-1/4" Cut.

It acts as a rigid base for the machine and a flexible workholding system. Higher chiploads are definitely possible (but may not be desirable), 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). Additional features include a slim and ergonomic design that weighs only 3.9 lbs., with a durable flat top design for added convenience when changing bits. Or, use a Feeds and Speeds Calculator Wood like our G-Wizard to make it easier. So the machine sees a "spike" in the cutting resistance at each corner. No Load Speed (variable speed) : 10,000 - 30,000 RPM Overall Length : 7-7/8" AMPS : 6.5 Maximum Horsepower : 1-1/4 HP Net Weight : 3.9 lbs. %PDF-1.3 % The most common signs of inadequate feeds and speeds are: : 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). Torrance, CA will be required to cut down to a total pocket depth of. "Feeds" and "Speeds" go hand in hand, what really matters is the, of feedrate and RPM values for a given situation. FYI: Here are the speeds vs. dial numbers for the CCR. We just posted our newest product, the Carbide Compact Router. A pretty neat feeds and speeds worksheet has been put together by @gmack on the Shapeoko forum (which he derived from an original worksheet from the NYCCNC website). 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. If the machine will let you pass larger materials through the machine, you can cut parts larger than the machines table size. 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. Router Bit 3/8" Corner Round, 2 Flute, 1/4" SH, CT, 1/4" Corner Round, 2 Flute, C.T. for this RPM to achieve the adjusted target chipload. 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. Router Bit, 1/4" Shank. Ive been cncing with your product for a little over a year now and went through 2 upgrades. Whichever version your choose, your Shapeoko CNC Router will become one of the most productive power tools in your shop. With a full 1-1/4 maximum horsepower, the RT0701C is engineered for a range of precision routing applications. ), the feeds and speeds are likely incorrect (too low or too high chipload), or the tool is dull and is rubbing rather than cutting. Shapeoko includes our Sweepy V2 dust boot to help keep your Shapeoko CNC router, and your shop, as clean as possible. should be used to name the adjusted/effective chipload after chip thinning is taken into account. There are a total of 11 possible speed settings for a Carbide Compact Router and few shop environments and folks and materials would be workable for the highest few, so one could instead just chart out all of them w/ the reasonable feed rates in suitably small increments and you could note the chipload for each intersection, and list materials Router Bit 3/8" Flush 1" Cut, 1/4" SH, C.T. If the toolpath uses some ramping at an angle into the material, they can be increased quite a bit. Then decrease speed by 10%. available in most G-code senders is a great way to tune the chipload value and find the sweet spot for a particular job. 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. Router Bit, 1/2" Shank, 1" Cut, Router Bit 1/2" Hinge Mort. : even without chatter, a poor surface finish can indicate that the final cutting pass was too agressive (too much chipload or too much deflection). say "RPM range is 12,000 - 30,000". Router Bit 3/8" Flush 1/2" Cut, 1/4" SH, C.T. Router Bit, 7/8" V.G., 2 Flute, 1/4" SH, C.T. Dust Collection: Dust is the enemy of a CNC router, and it makes a mess of your shop. The interesting thing about the MRR figure is that it allows one to. 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. Look for a machine with an easy-to-use interface that allows you to quickly and easily set up your cuts. Router Bit, 1/2" Shank, 2-1/2" Cut, Router Bit, 7 Bevel Trim, 1/4" SH, Solid Carbide, 5/8" Straight, 2 Flute, C.T. 1 Like WillAdams (William Adams (Carbide 3D)) September 12, 2019, 8:01pm #4 However, it is generally a good indication of the router/spindle speed for most CNC operations. There's only one reason to buy this router over the less expensive Carbide Compact Router: you need to use cutters or drills with a shank diameter other than 1/8" and 1/4". For a smaller stepover, say 25%, the TEA will be reduced (in this case to 60): 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. Router Bit, 1/2" Shank, 1-1/4" Cut, Router Bit 1/4" Straight 2 Flt 3/4" Cut 1/4" SH CT. Router Bit 1/4" Cove, 2 Flute, 1/4" SH, C.T. One thing to remember is that the chart, even if measured is not 100% accurate and there may be differences between one router/spindle and another similar at the same setting. 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. Most of that time is spent on the Hybrid Table, which has a lot of screws, but the payoff is a rigid machine with great workholding. Carbide 3D's "Carbide compact router" (CCR), for the US only, which is a close sibling of the Makita. Router Bit, 1/2" Shank, 1-1/4" Cut. 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. 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. Since the cutter does RPM revolutions per minute and each of them is 2Pi radians: or in the Imperial units converting Nm to lbfin (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. Get DIY project ideas and easy-to-follow crafts to help you spruce up your space. All Shapeoko CNC Routers come with a dirty dozen of our Teez-Nutz and six of our fiber-reinforced nylon Essential Clamps that wont break your cutter if they get hit. For the "narrow and deep" cut scenario (small WOC, large DOC), I like to use these guidelines: possibly even less for the hardest materials (, If you go for narrow and deep (and you should!

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.
