| Summary: | In recent years, industry spend almost quarter amount of the actual annual
spend only for performing the metal removal operation. In order to cut this amount,
it is necessary to understand the machining process that shall be done and the
machinability of the material. While machining is the process designed to change the
size, shape, and surface of a material through removal of materials, machinability
came as important as the ease with which it can be machined. However,
machinability is not a property of a material but an attribute. With this attribute, there
are four major factors which are surface roughness, chip formation, tool life and
cutting force. Material made of aluminum and mild steel is widely use since they are
the cheapest material compare to the other steel that not require very high strength.
Therefore, to manufacture components economically, engineers are challenged to
find ways to improve machinability without harming performance. Machinability
can be difficult to predict because machining is such a complex process. In short, a
good material with good machinability is the one that require low power
consumption, low tool life and have high surface finish rate without surface damage. |
