Feed rate = RPM x chip load x number of teeth. This formula gives you feed rate in IPM or mm/min based on whether you used the metric or imperial table. If you prefer to use cutting feed (IPR) instead of feed rate, you should remember not to multiply by RPM. So, cutting feed = chip load x number of teeth.

One place I worked running a CNC mill there was a job we hogged out aluminum with a 3" face mill, indexable carbide. If I recall, we ran it at 3000 RPM (I think that was top speed or close to it for the machine), feed was something like 50 inches/minute, 1/4" depth of cut (full depth of the inserts). Took like two/three seconds at most to make ...

Get comfortable using a sine bar. These are simpletouse, deadly accurate tools for setting angles. The sine bar should span the ways of a standard milling vise. Don't think of these tools as too precious for everyday work. Smaller sine bars are handy for manual mill work. One with a 3" to 5" center distance is ideal.

Golf ball backspin is the backwards rotation of the golf ball impact.

A ball nose bit is basically the same thing as an end mill, except the end is a ball. This will give you a rounded contour around the edges of your cut. ... So, while you'll cut more material per spin with 5 flutes, the lower spin rate may mean that using fewer flutes is more efficient since you can cut faster with 2 flutes than you can with ...

Let's start by describing exactly what a knee mill is. This diagram should help: And for comparison, I've also shown a "Bed Mill". The main difference is that with a knee mill, the table moves up and down in Z, whereas with a Bed Mill it is the spindle that moves up and down. Note that Knee Mills also have what's called a "Quill".

We want to focus on the spin, what the axis is, and how that is related to the movement of the pitch. Even more specific, you can have two pitches with the same velocity and spin rate but have different movement profiles based on the axis of the ball. Below is a pitch with a "1:00" spin axis and a 95% spin efficiency, based on Rapsodo metrics.

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. Let's say we decided to go for 16,000 RPM instead, the required feedrate would become: × 3 × 16000 = 144 ipm ×3×16000 = 144 ipm.

Use a towel or your shirt to wipe your hands. 2. Hold the ball so that the seam runs horizontally. The standard way to hold the ball when you bowl is to line up the seam so that it runs vertically in your hand. To bowl offspin, you need to grip the ball so that the seam runs horizontally to help line up your fingers.

If we keep rpms constant, Surface Speed is directly proportional to diameter. The 1/16″ endmill at the bottom is travelling 1/8 as fast in terms of Surface Speed as the 1/2″ endmill at top. Hence, to achieve a given Surface Speed, small tools will have to spin faster and large diameter tools will have to spin slower.

Ball (or rounded) ends are best for 3D carving. Vcarve bits are often used to create complex letters for sign making. They can also be used to chamfer edges and create countersinks for screw holes. What's the difference between a squareend bit and an end mill? An end mill has cutting flutes that extend across the bottom (end) of the bit.

So, is that supposed to be fast? When you consider the typical blade length for wind turbines, you see that the tip of the blade would easily go as fast as 100 mph to 180 mph depending on their RPM. A safe short answer to the question of "how fast does a wind turbine spin" would be "something around 100 RPM an up"! Image from Envato.

With larger diameter tools you may be stepping down 50% of the tool diameter. But when using miniature end mills with a higher flute count, only step down between 5% 15%, depending on the size of the diameter and risk of deflection. The feed rate should be increased to compensate for the decreased axial engagement.

Backspin in long toss produces lift, causing the ball to resist the force of gravity and fly further. At the same initial trajectory and velocity, a throw of higher spin rate will fly farther. Sidespin, another variable in the equation, reduces this effect of hang time by producing a lateral Magnus force, reducing the lift of the ball.
