Machinability

The machinability rating of a material attempts to quantify the machinability of various materials It is expressed as a percentage or a normalized value The American Iron and Steel Institute (AISI) determined machinability ratings for a wide variety of materials by running turning tests at 180 surface feet per minute (sfpm)Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, , utilizing large earth-moving equipment, belt conveyors, and machines specifically designed for crushing and separating various sizes of aggregate, to create distinct product stockpil.
