Manufacturing Requires: Special buildings or places of work Organisation of people Organisation of tools & equipment Communication systems Efficient working methods Health and safety considerations

Manufacturing Terms Primary Processing Secondary Processing

Primary Processing Turning raw materials into useful stock sizes Materials come from: Out of the ground Animals Trees & plants Oil

Making Paper Trees cut & shredded Water added Boiled up to make wood pulp Chemicals and dyes added Pulp poured over fine mesh and squeezed between rollers

Secondary Processing Casting & moulding Forming Wastage (or separation) Conditioning Assembling Finishing

Casting & Moulding Injection Moulding Die Casting Food Moulding

Forming Drop Forging Pressing Line Bending

Wastage Sawing Turning Milling

Finishing Painting Printing

Manufacturing Costs Finance Labour Costs (or Automation) Transportation Energy Plant Raw Materials

Scales of Production One-off or Jobbing Production Batch Production Mass or Flow Production Continuous Production

Just in Time Shared information systems Reduced lead times Less finance tied up in stock

Flexible Manufacturing Benefits of one-off production at mass production prices Only possible with ICT

Computer Integrated Manufacture All the computer functions are integrated together in a fully automated system. This would include moving materials/assemblies between machining operations.

Quality Issues Consistency Right first time every time Working to tolerances Materials in as well as products out

Quality Assurance Procedures to manage all functions which affect quality QA checks the systems Monitors processes Applies standards Part of the Total Quality Management (TQM) of the company

Quality control One part of QA A series of checks – size, strength, weight, taste etc.

Tolerances Acceptable range of difference from standard Sometimes measured in plus/minus No product manufactured in quantity can be considered to be perfect in every detail

Certification Manufacturers who work to recognised standards are awarded certification

BS EN ISO 9000:2000 One of the most important series of standards, these provide companies with a framework for developing a set of processes that ensure a common sense approach to the management of the organisation.
