Machining is one of the most important manufacturing processes, which
remove unwanted material in the form of chips from a workpiece. Material
removal operations are among the most expensive; in the U.S. alone, more
than $100 billion were spent on machining in 1999. These high costs put
tremendous economic pressures on production managers and engineers as
they struggle to find ways to increase productivity.
Machining recommendations provided in this book cover turning since it
allows removing more material per unit of time and consuming more power
at the roughing operations than end milling, boring or drilling.
Machining recommendations relate to cutting speeds, feed rates, and
depth of cuts. Such recommendations depend on the workpiece material
properties and the cutting tool material. Workpiece materials described
in this book are the most commonly used grades of carbon, alloy,
stainless, tool, and maraging steels. Cutting tool materials are
cemented carbides, cermets, and ceramics.
Describes hardness, tensile strength, and machinability of steels-the
major mechanical properties. These properties are taken into
consideration when selecting machining parameters.Features machining
recommendations for turning that provide the cutting speed values based
on Brinell hardness numbers, the depth of cut, and feed rate in
relationships with the type of steel. Summarizes numerous calculations
in five appendices.
