The Oregon Trail was very hard; people would walk for most of the day, and there weren't very many opportunities for fun.t was very tedious and exhausting, not much fun at all. About 1 in 10 people did not even survive the trip----it was that dangerous to follow the trail across the continent.
Turning is the machining operation that produces cylindrical parts. In its basic form, it can be defined as the machining of an external surface: with the cutting tool feeding parallel to the axis of the workpiece and at a distance that will remove the outer surface of the work.
Machining is a part of the manufacture of many metal products, but it can also be used on materials such as wood, plastic, ceramic, and composites. A person who specializes in machining is called a machinist.here are many kinds of machining operations, each of which is capable of generating a certain part geometry and surface texture. In turning, a cutting tool with a single cutting edge is used to remove material from a rotating workpiece to generate a cylindrical shape.
