1. First of all, we must learn two-dimensional drawing CAD two-dimensional drawing software CAD, this software is not difficult, but there must be a basis for practical drawing knowledge. It is recommended to find a book such as "Mechanical Drawing" online for reference, which will teach you how to draw a standard industrial drawing from scratch, and the main points are all in it. After reading the book, take a part, first survey and map, measure its size, and then use pen and paper to put three views (three views understand?).
Middle school knowledge, mechanical undergraduate course called "Drawing Geometry"), according to the knowledge points in the book, step by step to animate the standard drawing hands. This step is very important, it is the basis of all drawing, without this foundation, you will feel very abstract later. After the manual drawing is completed, follow the tutorial in the book or online to draw the drawing in CAD to the electronic file. CAD is very simple, just a few functions, find some videos online to understand. But pay attention to the fact that at the beginning you must draw the CAD drawings from scratch, do not use online templates (there are too many resources on the Internet, there are everything), choose from the size of the drawings (A3/A4...). ), frames, parts, technical requirements, main picture (three views) to the final annotation, from scratch, deepen the impression. Repeat the above steps a few times, draw a few more workpieces, and basically you will master the flat drawings. Not difficult.
2. After learning two-dimensional learning and three-dimensional drawing, the mainstream structural design software in the industry is generally pro/E and soliworks, and UG will be used in mold design. If you want to learn structural design, it is recommended that you learn pro/E, which is most used in the consumer industry.
Or you look at what your company uses, you can learn anything, and if you don't understand, you can also ask them, convenient. Learn one, the others are not bad. In the case of 3D software, it takes a little time and effort to learn it well. Three-dimensional software is actually a bit like stacking blocks, it is a continuous arrangement and combination of basic modules (bosses, slots, chamfers, cavities, shells, etc.) and basic functions (rotation, cutting, mirroring, sections, etc.) to build a composite three-dimensional structure. There are a lot of things in it, and it does take time to eat it through. You can find video tutorials online, start from 0, watch and practice while watching, and when it is almost done, take a few parts with complex structures to draw by yourself. After learning 2D and 3D, you have mastered the most basic things of institutional design.
3. Learn "Mechanical Principles". It mainly introduces the basic principles of mechanical transmission.
4. Learn "Mechanical Design". This course is also a core course, focusing on the theoretical knowledge and design points (tolerance level, fit, interchangeability, etc.) of common standard parts (such as gears, screws, threaded holes, bolts, etc.).
5. Learn "Materials Science". To be honest, the undergraduate mechanical major in materials science, there is actually nothing in it, just introduce some basic knowledge of materials, most of them are steel, and the practical application is far from the same. In this course, you can directly understand, ask more, and see more information in the company, which is much more than you can find this "Materials Science". Or which industry you want to enter in the future, just ask online or with people in the same industry what materials are mainly used in this industry.
6. "Metalworking Internship". The part is designed, how to process it? Manual, that is, turning, mushrooms, planing, milling, pliers, etc., each processing has a corresponding lathe. This manual (CNC is programmed, but also manually programmed) is suitable for individual or small number of workpieces. Now the industry, especially consumer ones, generally design molds first, and then use molds to produce in large quantities.
