Computer gongs processing machinery processing drawings how to look

1. Understand the shape and structure of parts and the corresponding graphic position.
2. Look at the benchmark of parts. Axis line, hole center line, surface, etc.
3. Look at the important dimensions, accuracy, roughness, geometric tolerance, etc.
4. Look at the technical requirements, materials, etc.

Look at the machining drawings. You need to

1. Understand the shape and structural dimensions of parts, and the corresponding graphic position of each line in the drawing. For this project, you need to learn descriptive geometry first.
2. Re learn tolerance and interchangeability, understand the machining datum plane of parts and the tolerance requirements.
3. Also need to learn mechanical drawing and mechanical principle, understand various drawing specifications, outline and design drawings of center line, shaft, transmission parts, structural parts, etc. Understand key dimensions, accuracy, roughness, geometric tolerance, etc.
4. It is also necessary to understand the expression method of materials, heat treatment and surface treatment of materials, and the description in technical requirements or technical conditions.
