With
more and more innovations created in the automobile and manufacturing industry
nowadays, the demand for high precision surface finishing is also increasing
using CNC milling. Newer applications in the automobile and manufacturing industry
are continuing to be developed and this, in turn, gives pressure to precision
engineers. With the demand for supplying high precision workpieces, both the manufacturing
company and engineers have the responsibility to increase the productivity
without compromising the quality of the workpieces. Both are in charge of
making quality products for them to remain competitive in the market.
Surface
roughness or surface finishing is one of the essential requirements for
any machined products. This is because the surface is the one in direct contact
with the stresses, temperatures, friction and corrosion. Alternatively, in aerospace
components, the surface does have the direct effect with the fatigue strength,
corrosion resistance and creep life. The visible parts of the workpieces have
to be finished according to the cosmetic or aesthetic requirements of the
manufacturer while the internal parts should be made with the focus of
functionality in mind.
In
order to achieve quality surface finish, speeds and feeds are considered. Both
should go hand in hand because their combined work affects the process of
cutting. When calculating for the speed and using feeds, one should not make
the mistake of just guessing. Appropriate feeds combined with the right
calculation of speed are definitely vital to achieve a flawless surface. Tooling
and cutting conditions are the most important thing to consider if you are to
talk about feeds alone. Logically, you cannot achieve quality surface finish if
you have deflecting or chattering tools. On the other hand, considering speed
means sensitively controlling the computer in the same way machining quality is
controlled.
Surface
quality is definitely a good indicator that could tell if your product is of
good quality. The quality of the surface influences the wear resistance,
fatigue strength, coefficient of friction and resistance to corrosion of your
workpieces. The industry that we have today relates the quality of the surfaces
with the level satisfaction of customers.
