The Realities of Modern Manufacturing Globalization - Once underdeveloped countries (e.g., China, India, Mexico) are becoming major players in manufacturing International outsourcing - Parts and products once made locally are now being made offshore (in China or India) or near-shore (in Eastern Europe) Local outsourcing - Use of suppliers locally to provide parts and services

More Realities of Modern Manufacturing Contract manufacturing - Companies that specialize in manufacturing entire products, not just parts, under contract to other companies Trend toward the service sector Quality expectations - Customers, both consumer and corporate, demand products of the highest quality Need for operational efficiency - manufacturers must be efficient in in their operations to overcome the labor cost advantage of international competitors

Manufacturing Approaches Automation Flexible manufacturing Quality programs Integration Lean production

Production System Defined A collection of people, equipment, and procedures organized to accomplish the manufacturing operations of a company

Facilities – Factory and Equipment Factory, production machines and tooling, material handling equipment, inspection equipment, and computer systems that control the manufacturing operations

Manufacturing Support Systems Business functions - sales and marketing, order entry, cost accounting, customer billing Product design - research and development, design engineering, prototype shop Manufacturing planning - process planning, production planning, MRP, capacity planning Manufacturing control shop floor control, inventory control, quality control

Computer Integrated Manufacturing

Automated System Examples: Automated machine tools Transfer lines Automated assembly systems Industrial robots Automated material handling and storage systems Automatic inspection systems for quality control Automated System Automated System Periodic Worker Periodic Worker Transformation Process

Three Automation Types Programmable Automation Flexible Automation Fixed Automation Variety Quantity

Fixed Automation Sequence of processing (or assembly) operations is fixed by the equipment configuration Typical features: Suited to high production quantities High initial investment for custom-engineered equipment High production rates Relatively inflexible in accommodating product variety

Programmable Automation Capability to change the sequence of operations throug reprogramming to accommodate different product configurations Typical features: High investment in programmable equipment Lower production rates than fixed automation Flexibility to deal with variations and changes in product configuration Most suitable for batch production Physical setup and part program must be changed between jobs (batches)

Flexible Automation System is capable of changing over from one job to the next with little lost time between jobs Typical features: High investment for custom-engineered system Continuous production of variable mixes of products Medium production rates Flexibility to deal with soft product variety

Reasons for Automating 1.To increase labor productivity 2.To reduce labor cost 3.To mitigate the effects of labor shortages 4.To reduce or remove routine manual and clerical tasks 5.To improve worker safety 6.To improve product quality 7.To reduce manufacturing lead time 8.To accomplish what cannot be done manually 9.To avoid the high cost of not automating

Automation Principle 1.Understand the existing process Input/output analysis Value chain analysis Charting techniques and mathematical modeling 2.Simplify the process Reduce unnecessary steps and moves 3.Automate the process Ten strategies for automation and production systems Automation migration strategy

Automation Strategies 1.Specialization of operations 2.Combined operations 3.Simultaneous operations 4.Integration of operations 5.Increased flexibility 6.Improved material handling and storage 7.On-line inspection 8.Process control and optimization 9.Plant operations control 10.Computer-integrated manufacturing
