The document discusses the basic requirements and design considerations for running a wind mill. It notes that atmospheric pressure should be 8.5 bar and efficiency increases for every 10 meters in height. Blades should be airfoil shaped and made of materials like NACA 44 or 63 to withstand all weather conditions. Running wind mills …
3. 1.2 Introduction Milling is a cutting operation with a geometrically specified cutting edge in which the tool makes the rotating main movement, and the feed as well as the infeed movement are generally made by the work part. Milling operations are classified according to the position of the milling axis towards the work part, i.e. between face …
"Bridgeport" style mills, these versatile mills are capable of performing many operations, including some that are similar to those performed on the drill press like drilling, reaming, countersinking, and counter boring. Other operations performed on the mill include but are not limited to side and face milling, fly cutting, and precision boring.
