Sharing a few facts related to machinery that are not easy to beat is the author's experience accumulated in his usual work:
1. The number "7" is very unpopular in the machinery industry. For example, you can hardly buy M7 screws on the market, and 7mm shafts and bearings are not very common. If you insist on designing a part to be welded with 7mm thick steel plates, your boss may make you mentally retarded.
2. "One millimeter" is a fairly large scale in the machinery industry, even in the entire manufacturing industry. If one day you see an advertisement like "accurate to the millimeter level" on TV, remember to block this company.
3. "Automation" is not equal to "robotization". Those who can use robots are usually only a small part of the automated assembly line. Why? Because there is no need.
4. Robots are rarely used directly in processing procedures, especially metal cutting. Because the reaction force of cutting metal can break the arm of most robots. Except for the fine work of deburring.
5. There are two commonly used power sources in factories: "electricity" and "gas". The power source refers to the total supply system that can be drawn out by plugging in a plug, and "gas" is high-pressure air.
6. Continuing from the previous article, in the two driving modes, the higher the proportion of "gas", the dirtier the factory is.
7. Some people who do machinery, including me, like to think of the users of the equipment they design as a kind of creature whose skin is broken at the touch of a touch, but whose hands can reach into all kinds of strange gaps without a brain, and then according to Funding determines how much safety measures need to be added to prevent the creature from being injured.
8. In the past two years, artificial intelligence, which has been watching every second, can only process production data in actual mass production.
9. 3D printing (rapid prototyping) is a technology that was actually produced more than 30 years ago, and then was dug up by some media with ulterior motives. Advances in this technology at this stage are largely dependent on advances in materials science.
10. There are very few machines that can work exactly as designed after they are manufactured. At this time, on-site adjustment (xia) and trial (zheng) are required.
11. After working in this industry for a long time, you can really tell how thick the screws in your hand are without taking a ruler, and the accuracy rate is at least 90%.
