Pre-requisites - None

Core/Elective - Core Course

To enhance students’ knowledge on quality and reliability engineering related topics so that they can analyse and solve industrial problems to improve the quality and reliability of products, manufacturing processes and systems.

At the end of this course, students should be able to:

1. Explain the importance of quality as a manufacturing concept and discuss the significance of quality for products and processes.

2. Evaluate metrology as a quality engineering aspect, determine dimensional standards of limits, fits and tolerances and be skilful in using modern metrological instruments for industrial applications.

3. Derive and use control charts, comment on the statistical control of processes and define process capability.

4. Demonstrate ability to refer to local and international standards on quality, apply and be resourceful in improving products and processes as per local and international standards.

5. Define and apply maintenance strategies for manufacturing related processes.

1. Introduction: Introduction to quality (definitions), dimensions of quality Quality gurus and concepts (Deming, Crosby, Juran, etc.) Evolution of quality, phases of quality engineering: quality planning, quality assurance and quality control

2. Variability: Categorization of total variation in a system [Measurement system variation (Gauge R&R study) and product or process variation (special and common)], Control Charts (attribute and variable), Process capability, Introduction to conventional view of quality (Goal Post Approach) and Taguchi’s Philosophy on Quality, Introduction to Cost of Quality

3. Quality Engineering: Quality Tools (7 control tools), Management aspects of quality (Introduction to Total Quality Management (TQM), Six-Sigma, and DFSS), Introduction to Robust design [Design of Experiments (DOE), Response Surface Methods (RSM), Taguchi’s approach]

4. Metrology: Engineering metrology for assessing quality and conformance of products, international standards of limits, fits and tolerances, interchangeability, modern measuring instruments, introduction to Coordinate Measuring Machine (CMM)

5. Reliability of Machines: Reliability engineering, machine standards, axis selection, accuracy standards, ISO 230, ISO 10796, ISO 941

6. 6 Reliability of Processes: Maintenance strategies, preventive maintenance, effects of maintenance on quality, Overall Equipment Effectiveness (OEE), quality as a tool for improving OEE, Total Productive Maintenance (TPM), ISO 9000 series and applications.
