The RPM formula for tapping is no different from the other formula we have been using, but the consideration mentioned for tapping must be made before we actually do any power tapping. Until you know how the tap will operate under your conditions, start with 1/3 to 1/2 the calculated RPM and gradually increase the RPM to the capacity of the conditions.

For turning applications we do not need this formula since Spindle Speed is usually given in Constant Surface Speed (CSS), which uses SFM value directly. But if you still want to use RPM formula, then diameter value is the actual diameter of work piece. Calculating Spindle Speed (RPM): RPM= 12 x SFM 3.14 x Diameter

Milling Step-over Distance Calculator. In many milling operations, the cutting tool must step over and make several adjacent cuts to complete machining a feature. As a result, a small cusp of material, called a scallop, will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used.

Critical speed is the rpm at which the media will be stuck to the side of the jar based on centripetal force. All of the values in the formula are to be used in inches. I'm not sure how the 265.45 value is derived, but it is based upon inches. Critical speed = 265.45 / sqrt (jar ID - media diameter) Optimal speed is 65% of the critical speed.

I think mine has like 9 or so. That means you only have so many to pick from so you can often just estimate the value in your head. Example the value for cutting with 4" silting saw in steel would be 100 RPM but on my mill 200 RPMs is my lowest range. So I set it at that lock everything I can down as best I can and put lots of coolant on it.

Milling RPM and IPM calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material. Understand Spindle Speed and Feed Rate – What is Milling Spindle Speed (Milling RPM)?

You can relate the RPM of an object turned by wind to the actual wind speed by first finding the circumference traveled by one of the object's arms in one rotation. You then convert this distance to either miles or kilometers and multiply that by the RPM to determine how much distance the object rotated through in 1 minute.

Next we can consider machining some aluminum stock. A SFM, on a benchtop mill or router, of 500 would be a safe starting point. Using the same end mill as in the previous calculation you get an RPM of 7,640 which, as you would expect, is double the previous result. Again when you calculate the feedrate it is double the previous result at 61 in/min.

C.S. = 76.63 / 11^0.5 = 23.1 rpm Ball and SAG Mills are driven in practice at a speed corresponding to 60-81% of the critical speed, the choice of speed being influenced by economical considerations. Within that range the power is nearly proportional to the speed. Mill rotating speed impacts grinding rates.

The RPM for a 0.500" would be 2400 RPM. 4*300/0.500"=2400 For drilling I use an exception of 50%, so 1200 RPM. But plunging any endmill directly into the material is hard. You basicly have to slow it down till it stops chattering or the chatter is exceptable. Drilling a hole first would help a lot.
