Document Summary

Mec 322 final review lathes, drilling, milling, saws, broaching, gears, cnc. Lathes remove material by rotating the stock and cutting off material using a single point. Swing is max diameter that can be rotated. Tool room lathes are smaller than engine lathes used to make tools they are very accurate. Turret lathe variety of different tools, allow faster production. Multiple spindle lathes multiple parts machined at the same time. Drill press 2 flutes on drill bit creates round holes. Milling tool rotates while work piece is fed. Circular saw (used to cut material low rpm to prevent over heating. Broaching removing metal with a tool which has teeth arranged in a row and gives good surface finish and close tolerances. Gears made from form milling or hobbing. Cnc 3 axis, 4 axis, 5 axis all possible. Longer reach bit results in more deflections and less accuracy. Better to design that can cut in 3-axis.
