How much effort should the machinery industry make from the machining at the grass-roots level to the mechanical design! People who can ask such questions must be eager to learn and make progress! Generally working in the following workshop for 3-5 years. First of all, you should start with the lathe operator and work hard for about a year to master the specific requirements of the lathe operator's drawings, actual tolerance coordination, necessary precision requirements, tooling, working procedures, work card measuring tools and so on. Only in this way, the lathe worker will not scold the drawings under the force bar, and the lathe worker's processing foundation will be familiar with others soon. Only when you are familiar with all the processing equipment can you combine the theory you have studied for many years and gain experience. The design of work card measuring tools, tooling and innovative equipment can be clearly analyzed and the drawings are accurate. How many engineers come here like this.
