3. CADMAT Computer aided design, manufacture and testing. Computer aided design, manufacture and testing. Manufacturers need to maximise profit and reduce costs. Manufacturers need to maximise profit and reduce costs. Global manufacturing places pressure on manufacturers who have to: Global manufacturing places pressure on manufacturers who have to: –Compete with low cost imported products –Satisfy customer demands for shorter production runs –Satisfy customer demand for quicker delivery

4. What is CADMAT An extension of CAD CAM. An extension of CAD CAM. Fully integrates the use of computers at every level and stage of manufacturing. Fully integrates the use of computers at every level and stage of manufacturing. Computers are used to manage data and help the decision making process. Computers are used to manage data and help the decision making process.

5. Examples of CADMAT in Practice Gathering, storing, retrieval and organisation of data, information and knowledge. Gathering, storing, retrieval and organisation of data, information and knowledge. Computer model simulations to test new production methods or systems. Computer model simulations to test new production methods or systems. Mathematical analysis of designs.

Process and equipment control including the scheduling of routine maintenance. Process and equipment control including the scheduling of routine maintenance. Monitoring safety and quality. Monitoring safety and quality.

6. CADMAT Failure in one area can hold up the process. Failure in one area can hold up the process. Up to date (real time) data is needed immediately for the system to work. Up to date (real time) data is needed immediately for the system to work. The departments / sections that are involved could include: The departments / sections that are involved could include: –Business strategy –Manufacturing strategy –Manufacturing planning and control –Ordering department –Suppliers –Manufacturing cells –Assembly –Distribution department –Customers –Design department –Sales and marketing department

7. Project Data Management A system to centralise and manage all data generated from design and manufacture. A system to centralise and manage all data generated from design and manufacture. Stored on a secure database. Stored on a secure database. Allows rapid communication between departments, manufacturers and retailers. Allows rapid communication between departments, manufacturers and retailers.

8. PDM – On line order tracking PDM allows customers to follow the progress of their order on line. PDM allows customers to follow the progress of their order on line. Using the internet customers check their order using a unique code. Using the internet customers check their order using a unique code. They can track it from transaction through to despatch. They can track it from transaction through to despatch.

9. PDM - Advantages Fewer bottlenecks Fewer bottlenecks Improved quality control Improved quality control More accurate product costing More accurate product costing More effective production control More effective production control Making it easier to work at optimum capacity with minimum stock levels. Making it easier to work at optimum capacity with minimum stock levels. Increased flexibility Increased flexibility Higher productivity and profits. Higher productivity and profits.

10. Just In Time (JIT) Keeping stock in the factory (particularly for high volume manufacturers) is costly. Keeping stock in the factory (particularly for high volume manufacturers) is costly. This is because: This is because: Capital is tied up in raw materials, components, sub assemblies and unsold products. Capital is tied up in raw materials, components, sub assemblies and unsold products. Too much stock at the point of production can crate safety issues and lead to deterioration. Too much stock at the point of production can crate safety issues and lead to deterioration. Storage of raw materials etc costs money. Storage of raw materials etc costs money.

11. Aims of Just In Time (JIT) JIT ensures components are manufactured by suppliers hours before they are required. JIT ensures components are manufactured by suppliers hours before they are required. They are delivered to the factory in the correct order. They are delivered to the factory in the correct order. Aims of JIT Aims of JIT –Received just before they are needed. –Quick response to orders. –Quality and correct quantity supplied to customers –Waste is minimised (materials, time, resources) –All manufacturing units follow JIT.

12. Features of JIT Continuous operation Continuous operation All employees are responsible for quality All employees are responsible for quality Manufacturing is synchronised to avoid bottlenecks. Manufacturing is synchronised to avoid bottlenecks. Work is simplified using foolproof jigs, tools etc Work is simplified using foolproof jigs, tools etc The end product is the focus – anything that isn’t to do with the end product is not needed. The end product is the focus – anything that isn’t to do with the end product is not needed. Factory layouts are custom designed to minimise movement of materials and products.

13. JIT and Workplace Organisation Operational set up times are reduced. This increases flexibility and capacity to produce smaller batches. Operational set up times are reduced. This increases flexibility and capacity to produce smaller batches. Flexible, multi-skilled workers lead to greater productivity. Flexible, multi-skilled workers lead to greater productivity. Production rates are flexible. Production rates are flexible. Kanban control systems are used to control production rates. Kanban control systems are used to control production rates.
