ABSTRACT

Nowadays, the industrial manufacturing system in general and the
manufacturing process in the field of mechanical machining in particular are
developing in the direction of increasing automation. So the feeders is one of the
necessary requirements need to be studied and solved in automated production systems
aimed at improving labor productivity, use and exploitation of machinery, equipment
be a most effective way, improve product quality and reduce production costs.
In the field of mechanical machining, workpieces in bulk processing on a lathe
have very large number. The details of this type have not much volume processing. So
time for the feeders a very rate. Therefore, to calculate and design feeders system is a
complete way to increase productivity significantly. To feeders bulk of cutting process
in different ways. But feeders by the vibration method is a method for high
productivity, simplicity and popularity. Therefore, this thesis will study "Calculate,
design and simulate the automatic feeders system using vibrating hopper and robot
automatic feeders for type lathes NC Takamaz".
VII

Through the fact-finding process processing cutting machine NC Takamaz in
Maruei Viet Nam Precision company, in Viet Nam Singapore industrial park. The
researcher has analyzed, calculated the characteristics of the feeders processing current.
Thereby, the researcher give improved method feeders for NC lathes of the plant in the
direction automatically.
With the objectives and requirements of the initial set of automated feeders
system:
 Each NC machine need one worker  machine need
one worker after applying automatic feeders system.
 Waste product 
to 0%.
 Time feeders down 50% compared to the current method feeders.

On practical basis, the researcher calculated and designed the automatic feeder
system use vibrating hopper associated with conveyor and robot has 3 degrees of
freedom. To feeders bulk an NC lathe machining.
After calculated and designed, the researcher used SolidWorks software to
simulate principle of operation of this automatic feeders to see the role of each
structure in the entire the system. This result is the basis for our manufacturing system
the automatic feeders system applied to actual production of the plant.
