Skilled and often grasp the commonly used CNC punching M code, can be independent of the Any special molding die adjustment, and can live with M code (such as the use of front and rear workstation open and closed jaws loading and unloading)
Junior sheet metal processing operators should first have the ability to identify sheet metal parts design drawings, at least the general requirements of the design drawings and the various parameters should know what is the meaning of, and then master the operation of sheet metal machine tools, do not need to have a deep understanding of the machine tool, you only need to master how to use it. Master how to use on it, and then there is the need to help the simple installation of machine tool molds.
Intermediate sheet metal processing operators to have a certain degree of physical computing technology, can accurately calculate the relevant dimensions, and in the later production design to gradually improve the relevant drawings, which are deficient in time to supplement and improve, but also to understand the other types of machine tools and their use, you must be familiar with the principle of molds and the use of how to repair the relevant products.
