In broaching, a tool with a series of teeth called a broach is pushed or pulled over a surface on a work piece. Each tooth takes a thin slice from the surface. Broaching of inside surfaces is called internal or hole broaching; for most outside surfaces, it is usually referred to as surface broaching. Typical broaches: (A) special form broach; (B) titanium slotting broach for compressor disks; (C) semi-finish rack-gear form broach; (D) round broach used for half-round operation on connecting rods; (E) titanium dovetail roughing broach for compressor disks; (F) pine-tree finish broach for turbine disks; (G) re-broach for hardened gears. Broaching machines may be classified as: (1) push broaching machines, (2) pull broaching machines, (3) surface broaching machines, and (4) continuous broaching machines. Three common kinds of metal-cutting saws are hacksaws, circular cold saws, and band saws. Although different in overall form, they all contain a series of cutting teeth that operate in the same basic way. The important features of a saw are its: (1) material, (2) tooth form, (3) tooth set, (4) tooth spacing, and (5) size.
