Question

importance of rake angle in grinding operation

Answer 1

Useful production time and energy are being wasted
during regrinding or re-sharpening of cutting/turning
tools during machining operations. Machining is one of
the methods used in manufacturing engineering. Other
methods include: casting, forming, grinding, shaping,
finishing etc. The quest for profit maximization in
manufacturing process makes it necessary for
engineers and scientist to explore the optimum
processes which requires less time and minimum
energy for maximum output. Cutting tools are the basic
tools used in machining operations which involve
turning, milling, grinding, drilling, boring, planning
and shaping and therefore tool life has to be elongated
as much as possible in order to save time, energy and
resources for optimum profit generation by a
production firm. On this account, it has become
necessary for us to investigate the effects of cutting
parameters on tool life. According to Parson’s, (1966) in
1907, Taylor has indicated cutting speed as the major
determinant of tool lif
