Production metrology

" Production metrology is a generic term for all activities associated with measuring and testing tasks that have to be performed during the industrial development process of a product." An important sub-area of ​​production metrology is the measurement of length, angle, shape and surface, i.e. the measurement of the geometry of workpieces .

The most important task of the production measurement technology is the product development process, extending from development and construction through to delivery to the customer, information on the quality of products and processes in the form of measurement - to deliver and test data, which is the basis for quality assurance form . The term production metrology is not limited to technical processes for determining the measured values, but also extends to organizational aspects that are linked to measurement and testing technology in production .

Overall, production metrology can be defined as the quality control of the production methods and the products produced, as well as the economic efficiency . These include:

• ongoing testing of production processes and machine tools (see e.g. CNC machines )
• temporary review of their profitability
• ongoing non-destructive material testing
  • z. B. Radiographic testing , ultrasonic testing , thermographic
  • Checking the dimensions (see tolerance (technology) ) and dimensional accuracy (e.g. with dial indicators , strain gauges , micrometers , coordinate measuring systems )
• random destructive material testing
  • z. B. hardness test , vibration test , tensile strength
  • chemical resistance , heat resistance , thermal analysis
