Qr code
The following is about Chengdu large-scale machining benchmark introduction, let's understand it.
concept：
    Mechanical parts are composed of several surfaces. In order to study the relative relationship of parts surface, a datum must be determined. Datum is the point, line and surface on which other points, lines and surfaces are located. According to the different functions of benchmarks, benchmarks can be divided into design benchmarks and process benchmarks.

classification
Design datum: the datum used to determine the position of other points, lines and surfaces on the part drawing, which is called design datum.
Process benchmark: the benchmark used in the process of machining and assembly of parts is called process benchmark. According to different uses, process datum can be divided into assembly datum, measurement datum and positioning datum.
1. Assembly datum: the datum used to determine the position of parts in components or products during assembly, which is called assembly datum.
2. Measuring datum: the datum used to check the size and position of the machined surface, which is called measuring datum.
3. Positioning datum: the datum used for workpiece positioning during processing, which is called positioning datum. The surface (or line or point) as the positioning datum can only select the rough surface in the initial process, which is called rough datum. In the subsequent processes, the machined surface can be used as the positioning datum, which is called the precision datum.
Through the above introduction, I believe you have a relative understanding of Chengdu large-scale machining benchmark. If you have other questions, please consult our company for details.
