Introduction
Roundness is one of the important shape tolerances in product geometry specifications and is also a key technology for evaluating the geometric shape accuracy of rotating body products.
As one of the most basic geometric errors, roundness is of great importance in ensuring the geometric accuracy of rotating parts and improving the manufacturing precision of products.
The scientific and advanced roundness specification can not only reduce the manufacturing process, but also improve the roundness, working performance and reliability.
The error in the rotation can improve the working performance of the rotating body products, and can also significantly reduce the failure rate of the rotating body products and extend their service life.
With the development of digital measurement technology and product geometry specifications, the relevant definitions in the original standard are different from those in the current national
The GPS standard is not commensurate, and the technical requirements lag behind the current production needs, and cannot effectively regulate and guide the current market production situation.
It can better standardize and guide product geometric elements, provide technical support for enterprises in the design, manufacturing, inspection and other processes, and lead my country's high-end
The development of equipment manufacturing industry.
GB/T 24632 aims to specify the roundness specification of a single component and consists of two parts.
Part 1.Vocabulary and parameters. The purpose is to define the terms and concepts related to the roundness of single components.
Part 2.Set of specification operations. The purpose is to define a complete set of specification operations for the roundness of a single component.
The roundness specification must clearly define the set of operations to ensure its uniqueness, otherwise it is easy to cause ambiguity (see GB/T 24632.2).
For example, filtering is necessary for data extraction operations, and additional filtering may or may not be used when extracting data.
Mean line filtering (Gaussian filtering, spline filtering, wavelet filtering, etc.) or nonlinear filtering (such as morphological filtering), the filter type will affect the cylinder
The definition of the degree and the set of standard operations therefore need to be clearly stated.
This document specifies the terms and concepts required to define the roundness specification operation set of a single component according to GB/T 24632.2, and does not involve specific
Roundness measurement method.
