Study Notes

Introduction to Automation

Automation refers to technology designed to perform processes without human intervention.
Originated in 1946 at Ford Motor Company to describe automatic transfer devices in manufacturing.
Modern automation heavily relies on computer technologies, unlike early implementations.

Learning Objectives

Understand basic elements of an automated system.
Explain advanced functions in automation.
Identify various levels of automation.

Basic Elements of an Automated System

Three core components:
- Power: Required to drive processes and operate systems.
- Program of Instructions: Directs the process and handles specific manufacturing steps.
- Control System: Executes the program to achieve defined functions.

Power to Accomplish Automated Processes

Electric power is crucial in industrial settings and can be converted into different energy forms.
Allows for functions such as signal transmission and data processing.
Long-life batteries serve as a power source where direct electrical supply is unavailable.

Program of Instructions

Defines required actions for each automated process, tailored for specific parts/products.
Processing steps are executed during a work cycle; multiple steps can occur in environments like injection molding.
Work cycle programs dictate the operational sequence, often referred to as part programs in numerical control.

Advanced Automation Functions

Automation can perform complex functions beyond basic tasks to improve safety and efficiency:
- Safety Monitoring: Protects workers and equipment from hazards during automated operations.
- Maintenance and Repair Diagnostics: Assists in identifying system malfunctions, encompassing status monitoring and failure diagnostics.
- Error Detection and Recovery: Utilizes sensors to identify errors and enables automated systems to take corrective action without human input.

Levels of Automation

Automation is applicable across different levels of factory operations, influencing both machinery and their subsystems.
The complexity of automation increases as more subsystems become integrated into the overall control structure.

Review Questions

Understanding definitions and differences in automated systems, including:
- Automation vs. Mechanization: Automation replaces human oversight entirely; mechanization assists but still requires human input for cognitive tasks.
Recognizing the need for decision-making in programmed work cycles.
Distinguishing between closed-loop (feedback systems) and open-loop (no feedback systems) control systems.
