Comparison of computer aided production system with the conventional production system in a yatch furniture manufacturing factory

In this study; manufacturing of special furniture for yacht and cruise boats with computer aided manufacturing and conventional manufacturing systems and their manufacturability with CNC machines according to the quantity of furniture, piece and amount of boards were investigatedThe production of 60 different types of furniture for Hardtop 78 project is done with conventional machines. Data gained from this production are saved on Project and Excel 2007 software. As the selection of furniture for computer aided manufacturing, VIP cabin set identical to the 78 feet model and other test furniture were determined. Preparation for computer aided manufacturing is satisfied with CNC machines and its related software. Comparison is done with the data gained from two different manufacturing systems.As a result of study, 60 different furnitures of 78 hardtop project are 100% producible by traditional manufacturing system, but 68%(42 furniture) are producible compeletely by computer aided manufacturing. For all furniture only 32% (19 furniture) are participally producible by computer aided manufacturing system. The furnıture of 78 hardtop includes 943 components. When total number of furniture pieces is examined, 95% (894 pieces) is producible by computer aided manufacyuring system, 5% (49 pieces) is needed to be produced by traditional manufacturing system. Yacht furnitures include 277 m2 boards. 91% (253 m2) of all boards can be produced by computer aided manufacturing system, %9?u (24 m2 ) can be produced by traditional manufacturing system.The comparison between the costs of machines to the companies is based on the prices between 2006 to 2008. The total cost of 13 machines used in traditional manufacturing is 106.993 ? and 3 machines? used in computer aided manufacturing is 341.091 ?. It is identified that when the costs of machines are studied, the transition from traditional manufacturing to computer aided manufacturing is ricing up to the initial investment costs 3.18 times.In this study, it is determined that computer aided manufacturing system is advantageous for yacht furniture production. Beside the advantages of capacity and flexibility of machines, reduction in the number of employees, permanence in quality and standards of furniture, speeding up the manufacturing process and meeting customer demands more quickly are the other major advantages.At the phase of investment for the CNC and other machines that is needed to use for producing special furnitures such as yatch furnitures, the experts should study on construction of furnitures, materials is used and etc. for suitability to furnitures planned to manufacture.It is observed that CNC machine user companies should pay attention to design of furniture for manufacturability in CNC machines. Production development and manufacturing development departments should gain more importance in the companies. It is suggested to managers of such companies to have experts to make more feasibility studies on manufacturing.
