domestic product
• Manufacturing
employs 17% of the
U.S. workforce1

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

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 group
Work Envelope
– Range of motion of a robot or machine
– Degrees of freedom are individual movements
