Abstract

          This project concentrates on developing knowledge and capability about automatic control

system. The project is supported from industry which allows organizers to study problems that

occur in reality of the factory. When we had surveyed in processes of industry, we found that

most of the production line in this factory remains to implement by labor force. This situation

affects directly to product both low quality and producing delay as well. Therefore, the method

that can solve these problems effectively is developing the production line from labor force to

automatic or semi-automatic machine. This solution is presented to engineer in the factory and

they are consisted with it so the factory let the organizers to have a chance to present the solution

by building a prototyping machine which the factory can bring to modify for using in real situation

in the future. The important procedure that the organizers mention is the production line in bending

copper tube or header tube to various forms. Thus the organizers decided to build the tube

bending machine prototype for guiding to solve this problem. This machine prototype has

outstanding advantages such as bending the copper tube to various angles automatically, being

able to switch between automatic mode and manual mode, varying the bending point as much as

you want and displaying result with LCD monitor during operation. This project is considerably

useful for the organizers because it enhances our knowledge about automatic control and we can

also apply this knowledge to our work in industry.
