| Abstract | Nowadays, competition between companies is ve ry high. In order to have advantages over other competitors, the company has to not only provide good quality products but also offer competitive product price in short lead time. To achieve the above mentioned targets, one of the most effective methods which current industries often use is statistic process control (SPC). If a process is in control then we can expect that the quanti ty of nonconforming products is reduced. Consequently, the cost before delivery due to producing defective products can be reduced and delivery lead time can also be reduced. There are 7 SPC tools which are widely use d. Those are Histogram or Stem and Leaf Plot, Check Sheet, Pareto Chart, Cause a nd Effect Diagrams (Ishikawa or fishbone diagrams), Defect Concentration Diagram, Scatter Diagram and Control Chart. Control chart is the key tool in SPC for monitori ng and controlling the processes. Two main types of control charts which are widely used are variable control charts and attribute control charts. Variable control charts are us ed to control quality characteristics which can be measured such as length of bar, te nsile strength of materials, etc... while attribute control charts are used to cont rol quality characteristics which cannot be measured but can only be classified as “conforming” or “nonconforming”. In this thesis, the author will have a study about these two types of control charts and will apply the studied theory to construct c ontrol charts for copper cutting process in Siemens Busbar factory in order to improve this process. |
