Introduction to the Mill

In vertical mills, milling cutters with solid shafts are usually used. Milling cutters with keyed holes are predominantly for use in horizontal mills. End mills are designed for cutting slots, keyways and pockets. Two fluted end mills can be used to plunge into work like a drill. End mills with more than two flutes should not be plunged into ...

THE MECHANICS OF TENSION CONTROL

Remember the equation of torque = tension x radius is linear, so torque must be decreased (for unwinds) and increased (for rewinds) at a linear rate relative to roll radius. For example, if you start with a 17.5 inch roll radius (35 inch diameter) and unwind down to a 1.75 inch core radius (3.5 inch diameter); 17.5 divided by 1.75 is 10:1 ratio.

Looking downward from the top, a turbine with a Savonius rotor would look like two spoons facing opposite directions and linked at the center to the rotor axis (creating an 'S' shape in cross section (Fig. 20.14)).Due to their curvature, the drag of the concave surface is higher than the convex surface, forcing the rotor to turn when the cups are exposed to wind (Mathew, 2006).
