THIS IS OKAY. If you balance your pitch with great posture and great leg drive, you can throw pretty darn fast with bullet spin, or something in between bullet and 4seam spin. In fact, according to physics, 4seam spin may be marginally the fastest, but it also flies the straightest with the least movement. You might not even want that!

On my mid 90s Cincinatti Arow it runs out of contouring accuracy at elevated feedrates before it runs out of RPM (with a 1/2" coated carbide end mill, anyway). I let GWizard calculate the speed and feed ratio required to maintain chip thickness for cutter longevity (too thin of a chip promotes rubbing and tool edge wear) then scale back the ...

A smaller ball interpolated exposes more of the surface to a faster moving cutter, leading to a better finish. But, the smaller cutter can flex more. Hence the need to balance these two factors. If you have a 4th axis or 5axis mill, you can try "Sturz" milling to combat the slow moving tip. See below for details.

Material removal rate is how fast in cubic units your mill is making chipsthe faster the better for most machinists, right up until it creates problems. The most common problem is cutting tool breakage or chipping when you feed too quickly. When that happens, the chips jam up in the flutes and pretty soon the cutter breaks. ...

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.

To determine this (you might need to break out the calculator), simply multiply the recommended cutting speed by the value (round up to 4), and then divide by the tool diameter.

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.

How to Choose the Proper Speeds for Router Bits. Many modern woodworking routers allow you to adjust the RPM speed of the motor to match your needs. Choosing a speed can depend on the type of wood you are routing, but also on the type and size of the bit you are using. A tool spinning at too high an RPM may burn wood, while a tool spinning too ...

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.

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.
