Practices Unit code L/615/1484 . Unit level 4 . Credit value 15 Introduction . The complex and sophisticated engineering manufacturing processes used to mass produce the products we see and use daily has its roots in the handoperated lathes and - milling machines still used in small engineering companies. To appreciate the
8. The machine must be set to operate at speeds and feeds recommended for the specific metal being machined. If the metal rotates too slowly/fast or the feed is too slow/ fast, accidents are likely to occur. 9. Appropriate coolants should be applied to the material being 'turned' on the lathe.
Modern Engineering Practice was a series of one-page articles which appeared throughout Wonders of World Engineering.Here is a complete list of the articles, with links to the relevant issues.
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.

A milling machine is set up to drill holes in a circular pattern. The variable Bcount gives the number of holes, while Diam is the diameter of the drilled circle. The first hole is drilled at an angle Alpha from a reference mark on the circle. Our task is to compute for each hole, the x, y coordinate values where 0, 0 are the coordinates of the circle's center.
