1. (Size) Definition and scope of measurement
1. Definition:
Definition: All operations performed to determine the measured value.
Substance: The process of comparing the measured measure with the standard quantity or unit quantity and determining the quantitative value.
2. Measurement. 檢驗。 檢定三者區別
3. Geometric measurement range:
Length-wise
Angular aspect
Shape aspect (geometric tolerance, surface roughness)
4. Measuring instruments used in long measurement measurement:
Geometry measurement
Vernier ruler. Centicard. Scales. Block gauge. Height gauge. Measurer. Three-dimensional measuring bed. Optical measuring instrument. Optical flat plate. Optical projector. Tool microscopy. Laser interferometer. Laser scanners, etc
Angle block gauge. Angle gauge. Angle ruler. Right angle gauge. Cone metrics. Protractor. Combined angle ruler. Leveler. Three-dimensional measuring bed. Optical measuring instrument (optical projector. Tool microscopy. Laser interferometer. 自動視準儀。 Laser collimator) and so on.
In terms of shape:
