A method that known as Design for Assembly DFA was proposed to help designers considered assembly problem. Design for assembly is a process by which products are
designed with ease of assembly in mind. Most products are assembled manually and the DFA method for manual assembly is the most widely used. Each product has their own
assembleability than to determine weather the product good in assembly or not. The development of DFA has lead to development of Design for Manufacture DFM.
DFM is design that considered for manufacture. The DFA and DFM have strong relationship that gives benefit to manufacturing field. The manufacturing field has faced
many challenges and the survival in this field is by used effectives tools and infrastructure. The uses of DFA and DFA have been made widely and these tools have
lead to increasing in new design development.
1.2 Problem Statement
Nowadays, one of the major processes in manufacturing field was assembling parts. Many companies that involved manufacturing want to reduce cost of their product make
mass production and increase quality and reliability of the product. In assembling the product, there is opportunity for defective component and an assembly challenge. Delay
in components assembly and miscommunication with manufacturers can lead to delays and cost overruns. Many ways to reduce the cost have taken such as reduce time
assembling and simplified assembling process. Tolerance accumulation becomes more significant and may require additional design and manufacturing to produce an
acceptable assembly.

1.3 Objectives
1. To identify improvements on product assemblability using Lucas-Hull method 2. To evaluate product assemblability using Lucas-Hull DFMA software.
3. To redesign the product and re-evaluate its assemblability using Lucas-Hull method.
4. To identify process in assembling parts of the product. 5. To compared product assemblability before and after improvement.
1.4 Scope
In this project, parts of the product will be identified and analyzed. Assemblability of the product will be evaluated. Evaluation of the product is using Lucas-Hull DFMA software.
This evaluation is used to redesign and improved product structure. Redesign is on part of product and this will lead to redesign the product itself. It is also to compare product
assemblability before and after improvement. All the process of assembling parts that regarding for this project is discuss in this project.
1.5 Benefit of study
In this project, there are many benefit and advantages can get from this study. The knowledge that gains from this project is useful in manufacturing industry field. The
benefits that get from this study are: a. Gain more and further knowledge about manufacturing process especially
assembling process. b. Can enhance in using software that regarding assembling process.
c. Able to generate idea and can solve problem that occur in the project. d. Enable to analyze product and may able to outcome new design of product.
e. The result or finding from this study can be implementing by industry to improve manufacturing activities.
f. As a reference for future study. 3
