Chip formation

Chip formation is part of the process of cutting materials by mechanical means, using tools such as <a href="/facts/Saw/mh8PG7xy">saws</a>, <a href="/facts/Lathe/FjF9FYLR">lathes</a> and <a href="/facts/Milling_machine/PVXTgNyz">milling</a> cutters.
The formal study of chip formation was encouraged around <a href="/facts/World_War_II/2efV5L1U">World War II</a> and shortly afterwards, with increases in the use of faster and more powerful cutting machines, particularly for metal cutting with the new <a href="/facts/High_speed_steel/6m6SCmof">high speed steel</a> cutters. Pioneering work in this field was carried out by Kivima (1952) and Franz (1958).
Chip formation is usually described according to a three-way model developed by Franz. This model is best known within the field of machine tool design, although it is also used when an application area, such as <a href="/facts/Woodworking/JSttCtkP">woodworking</a>, requires a vocabulary to describe chip formation in more detail than is usually attempted.
