ME6001 QUALITY CONTROL AND RELIABILITY ENGINEERING L T P C 3 0 0 3
OBJECTIVES:
• To introduce the concept of SQC
• To understand process control and acceptance sampling procedure and their application.
• To learn the concept of reliability.
UNIT I INTRODUCTION AND PROCESS CONTROL FOR VARIABLES 10
Introduction, definition of quality, basic concept of quality, definition of SQC, benefits and limitation of SQC, Quality assurance, Quality control: Quality cost-Variation in process causes of variation –Theory of control chart- uses of control chart – Control chart for variables – X chart, R chart and chart - process capability – process capability studies and simple problems. Six sigma concepts
UNIT II PROCESS CONTROL FOR ATTRIBUTES 8
Control chart for attributes –control chart for non conformings– p chart and np chart – control chart for nonconformities– C and U charts, State of control and process out of control identification in charts, pattern study.
UNIT III ACCEPTANCE SAMPLING 9
Lot by lot sampling – types – probability of acceptance in single, double, multiple sampling techniques
– O.C. curves – producer’s Risk and consumer’s Risk. AQL, LTPD, AOQL concepts-standard
sampling plans for AQL and LTPD- uses of standard sampling plans.
UNIT IV LIFE TESTING – RELIABILITY 9
Life testing – Objective – failure data analysis, Mean failure rate, mean time to failure, mean time between failure, hazard rate – Weibull model, system reliability, series, parallel and mixed configuration – simple problems. Maintainability and availability – simple problems. Acceptance sampling based on reliability test – O.C Curves.
UNIT V QUALITY AND RELIABLITY 9
Reliability improvements – techniques- use of Pareto analysis – design for reliability – redundancy unit and standby redundancy – Optimization in reliability – Product design – Product analysis – Product development – Product life cycles.
Note: Use of approved statistical table permitted in the examination.
TOTAL: 45 PERIODS
OUTCOMES:
• Upon successful completion of this course, the students can able to apply the concept of SQC
in process control for reliable component production
