GB/T 7234 Geometrical Product Specifications (GPS) Roundness measurement terms, definitions and parameters
3 terms and definitions
The following definitions and definitions as defined in GB/T 7234 apply to this document.
3.1 Roundness error
The roundness error of the measured cross section is determined by the difference between the maximum radius and the minimum radius of the contour of the part under test.
3.2 Waviness error
Random or periodic deviation from the ideal circle of surface roughness, taking the range of wave width over a range of waves
For the waviness error.
4 measurement requirements
4.1 Instruments
4.1.1 Measuring instrument type
Measuring instrument for the contact roundness measuring instrument, for the sensor rotary or table rotary.
4.1.2 Measurement result output mode
There are two output methods of measurement, that is, graphic recording or parameter direct display. The same instrument can have one or two outputs the way.
4.1.3 frequency response, filter characteristics
For the nominal diameter of 3mm ~ 350mm rolling bearing parts, the measured contour frequency response range of 2u/r ~ 500u/r (u/r that […]
