Why Manufacture?
• Manufacturing accounts for 20% of the US gross domestic product
• Manufacturing employs 17% of the U.S. workforce1
1according to the National Science and Technology Council
Domestic Product Workforce

History of ManufacturingEarly 1900s
– Kiichiro Toyoda– Lean Manufacturing
Five areas drive lean manufacturing/production: – Cost– Quality– Delivery– Safety– Morale

Manufacturing Today
Automatic Storage and Retrieval System (ASRS)– Moves material vertically or horizontally between
storage compartment and transfer station or within a process
Automated Guided Vehicles (AGV)– Computer-controlled system using pallets to
transport work pieces to NC machine tools and other equipment in a flexible manufacturing system
Artificial Intelligence (AI)– Machines learn from experience– Knowledge used to problem solve

Manufacturing Today
Computer Integrated Manufacturing (CIM)
– Company-wide management philosophy for planning, integration, and implementation of automation

Manufacturing Today
Kaizen– Japanese word for “improvement”– Based on continuous improvement by everyone
Flexible Manufacturing Systems (FMS)– Adapts efficiently to changing need– Possibly increase productivity by 50%

Manufacturing Today
Just In Time Manufacturing (JIT)– Objective is to eliminate waste– Capable of producing mixed products– Utilizes cross-trained workers
Toyota Production System (TPS)– Applied to automotive manufacturing– Competes with mass production– Employs lean production strategy
Lean Manufacturing– Systematic elimination of waste– Entire system must participate to
produce effectivity

Manufacturing Today
Six Sigma (6σ)– Indicates measure of quality for near
perfection– Produces fewer than 3.4 defects per million
opportunities– Identifies and corrects causes of defects– Utilizes the five “whys” to uncover root cause
6σ

Manufacturing Today
Rapid Prototyping– Prototype made directly from a computer model– Several technologies
• Stereolithography• 3D Printing• Selective Laser Sintering• Fused Deposition Modeling
Workcell– Manufacturing resources
arranged into a groupWork Envelope
– Range of motion of a robot or machine– Degrees of freedom are individual movements
