IQC (Diploma Mechanical Engineering 6th)

1. Inspection (09 hrs) 

Introduction, units of measurement, standards for measurement and

interchangeability.  International, national and company standard, line and wavelength

standards.  Planning of inspection: what to inspect? When to inspect? Who should

inspect? Where to inspect?  Types of inspection: remedial, preventive and operative inspection,

incoming, in-process and final inspection.  Study of factors influencing the quality of manufacture.

2. Measurement and Gauging (22 hrs)

 Basic principles used in measurement and gauging, mechanical, optical,

electrical and electronic.  Study of various measuring instruments like: calipers, micrometers, dial

indicators, surface plate, straight edge, try square, protectors, sine bar,

clinometer, comparators – mechanical, electrical and pneumatic. Slip

gauges, tool room microscope, profile projector. Limit gauges: plug, ring, snap, taper, thread, height, depth, form, feeler, wire

and their applications for linear, angular, surface, thread and gear

measurements, gauge tolerances.  Geometrical parameters and errors:

Errors & their effect on quality, concept of errors, measurement of

geometrical parameter such as straightness, flatness and parallelism.  Study of procedure for alignment tests on lathes, drilling and milling

machines.  Testing and maintenance of measuring instruments.

3. Statistical Quality Control (16 hrs)

 Basic statistical concepts, empirical distribution and histograms, frequency,

mean, mode, standard deviation, normal distribution, binomial and Poisson, Simple- examples.

 Introduction to control charts, namely X, R, P and C charts and their

applications.  Sampling plans, selection of sample size, method of taking samples,

frequency of samples.  Inspection plan format and test reports

4. Modern Quality Concepts (09 hrs)

 Concept of total quality management (TQM)  National and International Codes.  ISO-9000, concept and its evolution

 QC tools  Introduction to Kaizen, 5S

5. Instrumentation

Measurement of mechanical quantities such as displacement, vibration,

frequency, pressure temperature by electro mechanical transducers of

resistance, capacitance & inductance type.
