Module Relationships

Various modules are linked to one another (e.g., Design & Technology/Physics; Materials and Manufacturing Processes; Manufacturing Management; Engineering Science) for reference.
Many linked modules influence Manufacturing Technology.
Specific modules (Metrology, Advanced Manufacturing Processes & Technology, Laser Materials Processing, Application of Product Design, Manufacturing Planning & Control) relate directly to Manufacturing Technology in a specific segment of the course.

Metrology

Metrology isn't the study of weather and climate.
It's the science of measurement and calibration.
This is the subject being taught.

Why Metrology Matters

Measurement ensures design specifications are met.
Calibration is essential for national/international measurement conformity and confidence.
Manufacturing companies must adhere to ISO 9000 and ISO/DIS 14253 standards.

Further Importance of Metrology

Identifies acceptable/unacceptable components/products.
Facilitates comparisons between manufactured items and established specifications.
Improves product quality, reduces defects and scrap, and boosts market share, competitiveness, and profitability.

Metrology Breakdown

1.0: Legislation and Standards
- 1.1: Law, Company practices (CCP), British standards (BS), European/International standards.

Measurement Unit Systems

Four common measurement units exist worldwide: British Imperial, Centimetre-Gram-Second (CGS), Metre-Kilogram-Second (MKS), and Systeme International d'Unites(SI).
The SI system is the legal measurement standard in the UK.

Changing the SI Measurement System

Definitions of units are continually improved enabling tighter tolerances and less waste.
The revised SI units apply across most scientific measurements.
The new SI definitions (May 20th 2019) affect four base units:
- Kilogram (Planck constant)
- Ampere (elementary charge)
- Kelvin (Boltzmann constant)
- Mole (Avogadro constant)

2019 SI Measurement System Definitions

1 metre: (m) the distance light travels in a fraction of a second.
1 kilogram: (kg) fixed numerical value of the Planck constant (h).
1 second: (s) duration of 9,192,631,770 periods of transition.
1 ampere: (A) fixed numerical value of the elementary charge (e).

2019 SI Measurement System Definitions (Continued)

1 kelvin: (K) fixed numerical value of the Boltzmann constant (k).
1 candela: (cd) luminous intensity of a monochromatic light source.
1 mole: (mol) one mole contains Avogadro's number of entities.
