Assembly: Refers to the process of assembling two or more workpieces together. As for the assembly of sheet metal structural parts, in principle, the assembly is responsible for the tapping of large painted parts and cabinets.
Packaging: refers to the process of protecting the workpiece for easy transportation.
The surface of the digital punch diagram is the front side: in the future, it is required to use the diagram surface as the front side when drawing the process drawing, because when symmetrical parts need to unify the burr direction, do not directly use the diagram surface as the reverse side, and the follow-up process engineers must improve, production If similar problems are found, they should be reported in a timely manner.
Burr up, burr down: In the future, technical specifications must be included in the technical requirements for the drawing quantity of the process. If found in production, it must be reported in time for improvement.
Pressure riveting downward, pressure riveting upward: In the future, technical specifications must be included in the technical requirements for the drawing quantity of the process, and if found in production, it must be reported and improved in a timely manner.
Countersunk hole upwards, countersunk hole downwards: In the future, it is required that the drawing quantity of the process must be described in the technical requirements, and if it is found in production, it must be reported and improved in a timely manner.
