3. CAM University TENAGA Nasional Lecturer: Habeeb Al-Ani Computer Aided Manufacturing UNITEN Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

4. Group Technology(GT) Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

5. Group Technology.... What is Group Technology? Simplification Approach Decomposition Approach Both accomplished through: Grouping Parts Grouping Routes Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

6. Group Technology.... Grouping Parts Form Parts Before Grouping Grouped Parts Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

7. Group Technology.... Grouping Routes Ungrouped Parts and Grouped Parts and Machines Machines Parts Machines Parts FamiliesMachines Cells

8. Benefits of Group Technology Reduced production lead time Reduced work-in-process Reduced labor Reduced tooling Reduced rework and scrap materials Reduced setup time Reduced order time delivery Improved human relations Reduced paper work Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

9. Two Basic Methods of Group Technology: 1. Classification -Visual method -Coding method 2. Cluster analysis Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

10. Visual Method Parts Before Grouping Grouped Parts Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

11. Coding Method A code is assigned to each part based on its characteristics, e.g., geometry, material, etc. Three basic types of coding systems: 1. Monocode 2. Polycode 3. Hybrid Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

12. Monocode system and part’s monocode Digit 1 Monocode System 1.Steel 2.Coppe 3.Bronze. Round and Straight 1 Inch and Straight1 2 Digit 2 Digit 3 No center hole 1 Single through center hole 2 Two center hole 1 Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

13. CLUSTER ANALYSIS APPROACH Cluster analysis is concerned with grouping of objects into homogeneous clusters (groups) based on the object features. The application of cluster analysis in manufacturing leads to grouping parts into part families (PF) and machines into machine cells (MC). The result of this grouping is implemented as: - Physical machine layout, or - Logical (virtual) machine layout Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

14. Implementation of GT: Physical Machine Layout Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

15. Implementation of GT: Logical Machine Layout Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

16. How to be solve the bottleneck production line 1. It can be machined in one machine cell and transferred to the other machine cell by a material handing carrier. 2. It can be machined in a functional facility. 3. It can be subcontracted. Lecturer: Dr. HABEEB ALANI University TENAGA Nasional
