acceleration of this process. Forced drying, by artificial heat is therefore vitally
necessary in industry to achieve time and cost reduction, and to increase output.

General cutting is one of the oldest arts,
practiced in the Stone Ages, but the cutting of
metals was not found possible until the 18th
century, and its detailed study started about a
hundred years ago (Tresca 1878, Taylor 1907).
Much of the progress in metal cutting can be
associated with the introduction of high-speed
steel tools by Taylor and the later use of cemented carbide tools (Schröter 1923). Each
of these permitted a large increase in the rate of metal removal and required lathes of
greater capacity. Advances in lathe design followed and the problems of stress and
temperature distribution in tools became more important. This gave an impetus to
fundamental studies which really began seriously at about this time with a classification
of chip form and discussions of the processes by which a chip could be separated from
the workpiece. Such discussions have continued ever since and there is now a fairly
extensive qualitative literature on metal cutting and the principles involved. Only quite
recently has this begun to develop into a detailed quantitative understanding of the
