Study Notes
Reasons Against Automation
- Low labor wages mean that automation might not be financially viable.
- Task complexity makes automation impossible.
- Short product life cycles make investment in automation unwise.
- Customized products require human flexibility in production.
- Manual labor is necessary to respond to fluctuations in demand.
- Manual labor reduces the risk of product failure at the early stages of production.
Labor in Manufacturing Support
- Product designers are responsible for creative design.
- Manufacturing engineers:
- Design production equipment and tooling
- Plan production methods and routes
- Other manual tasks include:
- Equipment maintenance
- Programming and computer operation
- Engineering project work
- Plant management
USA Principle
- Understanding the existing process:
- Input/output analysis
- Value chain analysis
- Charting techniques and mathematical modeling
- Process simplification:
- Reduce unnecessary steps and movements
- Process automation:
- Ten strategies for automation and production systems
- Automation migration strategy
Ten Strategies for Automation and Process Improvement
- Specialization of operations: Using specialized equipment for specific tasks.
- Combined operations: Combining multiple operations in a sequence at a single workstation.
- Simultaneous operations: Performing multiple combined operations simultaneously at a single workstation.
- Integration of operations: Linking several workstations together with automated material handling devices.
- Increased flexibility: Maximizing machine utilization in job shops to accommodate different product designs.
- Improved material handling and storage: Reduce non-productive time spent on material handling and storage.
- On-line inspection: Reduce scrap rates through automated inspection.
- Process control and optimization: Reduce individual process times through automated process control and optimization.
- Plant operations control: Utilizing computer networks within the factory to control plant-wide operations.
- Computer-integrated manufacturing (CIM): A comprehensive approach to integrate all aspects of manufacturing, from design to production, using computer technology.
Automation Migration Strategy For New Products
-
Phase 1 – Manual production:
- Single-station manned cells working independently
- Advantages: quick to set up, low-cost tooling
-
Phase 2 – Semi-Automated Production:
- Utilizing automated equipment with human operators
- Advantages: Increased production rate, improved product quality
-
Phase 3 – Fully Automated Production:
- Utilizing fully automated systems with minimal human intervention
- Advantages: Increased production efficiency, reduced labor costs
Production Systems
- Production Systems Definition: A collection of people, equipment, and procedures organized to accomplish a company's manufacturing operations.
- Production System Categories:
- Facilities: The physical factory, equipment, and plant layout.
- Manufacturing Support Systems: Procedures for production management, technical problem solving, materials sourcing, production flow management and quality control.
Production System Facilities
- Facilities include the factory, production machines and tooling, material handling equipment, inspection equipment, and computer systems that control the manufacturing operations.
- Plant layout: The physical arrangement of equipment in the factory.
- Manufacturing systems: Logical groupings of equipment and workers in the factory, including:
- Production lines: A sequential flow of workstations where each station performs specific operations.
- Stand-alone workstation: An individual workstation performing a specific operation.
Manufacturing Systems
- 3 Categories of Manufacturing Systems based on human participation:
- Manual Work System: A worker performs tasks without powered tools, using hand tools.
- Worker-Machine System: A worker operates powered equipment.
- Automated System: A machine performs the process without direct human interaction.
Manufacturing Support Systems
- Manufacturing support involves a sequence of activities consisting of four core functions:
- 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, Material Requirements Planning (MRP), capacity planning.
- Manufacturing Control: Shop floor control, inventory control, quality control.
Automation in Production Systems
- Two main categories of automation in production systems:
- Automation of manufacturing systems in the factory.
- Computerization of manufacturing support systems.
- These two categories often overlap as manufacturing support systems are connected to factory manufacturing systems.
- Computer-Integrated Manufacturing (CIM) integrates both categories.
Computer-Integrated Manufacturing (CIM)
- CIM uses computer systems to integrate all aspects of manufacturing, including design, production planning, production control, and business functions. This enables seamless data flow and real-time decision-making.
Automated Manufacturing Systems
- Common examples of automated manufacturing systems include:
- Automated machine tools
- Transfer lines
- Automated assembly systems
- Industrial robots for processing or assembly operations
- Automated material handling and storage systems
- Automatic inspection systems for quality control.
Types of Automated Manufacturing Systems
- Three primary types of automated manufacturing systems:
- Fixed automation
- Programmable automation
- Flexible automation
Fixed Automation
- Fixed automation refers to manufacturing systems where the sequence of operations is determined by the equipment configuration.
- Fixed automation is suitable for high production quantities and offers higher production rates than programmable or flexible automation.
- However, it is relatively inflexible in accommodating product variety.
Programmable Automation
- Programmable automation allows the manufacturing system to change the sequence of operations to accommodate different product configurations.
- It requires a significant investment in general-purpose equipment, leading to lower production rates compared to fixed automation.
- Programmable automation is suitable for batch production, but setup changes are necessary between production runs.
Flexible Automation
- Flexible automation is an extension of programmable automation that enables the system to quickly change over from one job to another with no lost time between jobs.
- It allows for continuous production of variable mixes of products, with medium production rates, and is highly adaptable to handle changes in product design.
- Flexible automation requires a significant investment in custom-engineered systems.
Product Variety and Production Quantity for Different Automation Types
- Fixed automation is well-suited for high-volume production of a single product.
- Programmable automation is suitable for producing a variety of products in lower volumes.
- Flexible automation allows for high-volume production of a wide variety of products.
Computerized Manufacturing Support Systems
- The objectives of computerizing manufacturing support systems are:
- To reduce manual and clerical tasks in product design, manufacturing planning and control, and business functions.
- To integrate Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) (CAD/CAM).
- To implement Computer-Integrated Manufacturing (CIM), including both CAD/CAM and business functions.
Reasons for Automating Manufacturing Processes
- Key benefits of automating manufacturing processes include:
- Increased labor productivity
- Reduced labor cost
- Mitigation of labor shortages
- Reduced manual and clerical tasks
- Improved worker safety
- Improved product quality
- Reduced manufacturing lead time
- Accomplished tasks that cannot be done manually.
- Preventing high costs associated with not automating.
Manual Labor in Production Systems
- Manual labor still has a place in modern production systems.
- Two areas where manual labor plays a role:
- Manual labor in factory operations.
- Labor in manufacturing support systems.
Manual Labor in Factory Operations
- The long-term trend is toward greater automation to replace manual labor.
- While automation continues to grow, manual labor remains justified in certain situations, such as:
- Handling complex tasks that are too difficult or expensive to automate.
- Responding to unforeseen challenges during production.
- Supporting highly customized products.
- Responding to rapidly changing market demands.
