The traditional practice of lighting craftsmen is to ensure that the specifications of the finished products are the same.

Don't say that the things made by different craftsmen are very different, that is, the same craftsman, the things made when he is in a good mood and when he is in a bad mood are different.

said that the bird gun equipped by the Ming Dynasty said that it was a three-money lead bullet, but in the hands of specific soldiers, there were from two coins and eight cents to three coins and two cents, and they were all qualified products.

The huge difference between the guns forced each soldier to process the lead bullets according to the caliber of the guns in his spare time, otherwise they would either leak or not fit in.

If you want to assemble rifled guns on a large scale, you must first improve the processing technology, specifically, to carry out process standardization.

Without process standards, it is difficult for craftsmen to collaborate with each other, not to mention that the components manufactured in the downstream workshop are assembled and used by the upstream factory.

Therefore, Su Chengyu made up his mind to take the opportunity of large-scale manufacturing of rifled guns to begin to promote process standardization throughout the Ming Dynasty.

Change the habits of the craftsmen of the Ming Dynasty to work in isolation, and turn the handicraft workshop into a real factory!

You know, it took Europeans hundreds of years to go from a craft workshop to a factory with standard processes.

However, once this transformation is completed, the production efficiency and product quality of the whole society will be greatly improved, and it will pave the way to industrialization. In terms of national strength, an industrialized or even semi-industrialized country can definitely destroy a group of agricultural countries. Later, Britain used the colonization of most of the world to explain this to people.

With the large-scale planting of potatoes and sweet potatoes, Su Chengyu believes that the food problem of Daming should have been basically solved. Moreover, as the Ming Dynasty continued to expand overseas, it could also obtain a large amount of food replenishment from maritime trade and colonies.

Having enough food is a prerequisite for the start of industrial development.

In addition, the advanced equipment in Su Chengyu's later planning is beyond the power of the handicraft workshop.

Firearms such as breech-loading guns. He has handed over to Song Yingxing the synthesis method of thunder * mercury, which is necessary for making rear-loading firing guns, and is now trial-producing in the laboratory in Ganzhou, of course, there is still a long way to go before it can be successfully synthesized.

However, once the trial production of Lei * mercury is successful, if you want to make a rear gun with good air-holding, precision machining ability is the most basic. It would never have been possible to achieve such a high level of precision without a handicraft workshop that had completed the standardization of the process.

As for more advanced rifled cannons and even copper-shelled bullets, etc., it is something that the handicraft workshop does not have to think about.

There is also the shipbuilding industry, and if you want to take the huge cake of maritime trade from the mouths of Western countries, you must have excellent sea vessels.

Although the shipwrights of the Ming Dynasty can now build large-sized sea ships, there is still a big gap compared to the warships of the Europeans.

Shipbuilding is a huge system project.

Su Chengyu remembered the characteristics and structure of many advanced warships, but with the current level of craftsmanship, it was absolutely impossible to complete the construction of these super-era giant ships.

In order to ensure that the merchant ships of the Ming Dynasty can travel safely to and from Europe and Asia without being harassed by European pirate countries, a fleet that can form an overwhelming advantage over the Europeans is indispensable.

Three days ago, a huge banner was hung up at the main entrance of the Fujing Ordnance Bureau, which read: Unified teaching, unified weights and measures, unified process flow, and unified verification. Below is also the handwritten payment of the current Ministry of Works, Lord Song.

The interior of the Ordnance Bureau is also very different from the past, the original messy workshop has repainted the walls, the ground is divided into several areas with thin wood chips, and signs have been set up on the side - "raw material area", "tool area", "map and nationality area", "waste parts area", "verification area" and ......

In the "tool making area", there are several work stations, each of which is equipped with a full set of equipment such as forging table, drill platform, anvil table, etc. There are also all kinds of rulers, triangles, compasses, protractors, and balance measuring tools, which are not only of the same specifications, but also of the same position.

Such a standardized and scientific and meticulous "production workshop" is not said to be in the Ming Dynasty, even if you look at the whole world, you can't find a second one. It was Su Chengyu who copied the full set of models in the workshop of the later Fang Vehicle Research Institute.

It's just that the craftsmen who are working in it are a little shrunken and don't seem to be used to it.

Lately, Li Jing has felt like he's back in time as an apprentice.

He spent the mornings studying with a large group of apprentices in the technical school. Half an hour to learn to recognize words, half an hour to learn the use of equipment and "industrial pattern" recognition.

Fortunately, he was in the advanced class in the "Craft Standards" class at the next hour, which allowed him to regain the feeling of an old craftsman in front of the group of apprentices who went to the elementary class.

He glanced at the "Standard Process Manual", although he couldn't recognize a few words, but there was a clear legend drawn on it, and he knew its meaning at a glance.

He looked at the diagram and pondered for a long time, and took out a "small sickle" from the new and delicate tools beside him, and suddenly remembered that this thing seemed to be called a vernier caliper.

According to the requirements of the "Process Manual", he repeatedly measured the size and thickness of more than ten places on the iron parts in his hand with a caliper, and muttered in his heart, it is still comfortable to use my old tape measure.

It reminded him of the old tools he had taken away, and although the new ones were extremely delicate, they were not as good as the guys he had been calling for more than twenty years.

There seems to be a discrepancy in size. Li Jing frowned again and frustrated the gun base in his hand, then measured it with a vernier caliper, and then grinded it again. This was repeated more than a dozen times, until the size of each place was the same as the requirements in the "Process Manual", then I wiped my sweat and went to the side of the drill floor to punch holes.

He weighed the iron piece in his hand and said to the craftsman beside him, "Usually such a small thing can be made in half an afternoon." Now it takes a whole day, but there is still a small half of it to be done. ”

The craftsman also nodded, "Who said it wasn't, but I don't know why it's so verbose." ”

When Li Jing put the gun base on the drill floor and was about to start drilling, a "supervisor" in white clothes next to him walked over quickly and stretched out his hand to stop him, "Lao Li, you have to start punching holes before the last process is verified, and one point will be deducted from the evaluation." ”

Li Jing was stunned for a moment, and said with a busy face: "I have carefully measured this size according to the "Process Manual", and there is no mistake. ”

But the prisoner ignored him, only took out a small notebook, drew a cross behind Li Jing's name, and then handed him a handprint.

Li Jing shook his head helplessly, and said in his heart that it was only a trial now, and he would have to be careful next month, and the evaluation award every month could have a whole tael of silver, which could withstand half a month's salary. And if the prison collects a fork, a penny of silver flies.
