I notice that End Mills are not available on the store.. but I dont see any recommended feeds or speeds for these tools listed. is there a reference somewhere? or an easy way to calculate this for wood or aluminum cutting
Waiting for you to write it? . Seriously - any guide for wood is only ever going to be a very rough guide - two pieces of timber from the same tree can have very different properties. Alex.
They sell the machines. they sell the Bits. they should for each bit atleast give you a starting point. listed on the product page. This chart is fine.. except if your using a 1/8" bit then what. I realize that each material/machine/bit will be different but listing three starting options depending on Alum\Wood\Acruylic for a workbee with the dewalt would be the min they should be able to provide
Judging by the product pages, Openbuilds appear to be a distributor for the vendor "SharkBits", who are likely an importer of an OEM's tooling given how many of these rainbow coated tools have shown up of late. Do SharkBits have feeds and speeds info on their website? I wouldn't necessarily expect MSC or McMaster to have speeds and feeds for Sandvik inserts, either. It would be nice, and customer-friendly, but it's not necessarily specifically their job.
It's not that difficult. Modify the settings in the chart above to suit your bit. As a guide, set your depth of cut to about half the diameter of the cutter you are using - the other settings should still be ok. For me personally, I set depth of cut to just under half the diameter, e.g. 1/8" bit (3.175mm), I set to 1.5mm or about 5% under the radius and set speeds and feeds slightly lower, mainly to extend cutter life.
Thanks for the heads up guys, we understand that having a good starting point for routing is important and Carbides handy chart is an awesome tool to print out and have near the machine for sure. We have been working with the manufacture to create tool db for importing into software such as V Carve, Fusion CAM as well as OpenBuilds Software as it becomes available. We will also look into making a printable chart as well for guys like us that like to have these on hand at the machine for the rpm settings on the router. Thanks for the feedback, we are excited to see all the cool projects that come from these new tools.
