One processing arm hangs down, and it locks in a fixed gear with a click;

At the head of the processing arm, a saw disc is rotating at high speed, which meets the log moving forward under the drive of the slide rail, and saws it into two pieces in a 'zilazila' sound.

The blade stepped forward, unfastened the fixture, and pushed one of the pieces open;

The other piece is fixed on the three-jaw chuck at the end of the processing table, so that it is suspended above the processing table as a whole.

After that, he returned to the 'station' and operated the turntable in front of him, changing to another processing arm and slowly lowering it.

Holding a lever in hand, pushing forward to shift gears, the original power transmission terminal has been changed from the previous 'circular saw' to the chuck at the end of the log;

Then, he pressed his feet left and right, and pedaled the pedal like a bicycle pedal, and pedaled as fast as possible.

The force is transmitted to the chuck through the gears, bearings, belts and other components inside the machine tool, and the log is driven to start a rotational motion.

After that, the blade hand finds the area that controls the second processing arm, twists several turntables with precise scales on the surface, and can be accurately positioned, and locks the traverse displacement of the processing arm to a certain position;

The vertical shift is also operated several times, so that the extremely short steel and wood 'knife' sandwiched by the head of this processing arm slowly approaches the outer edge of the rotating log at a certain stable chamfer angle.

The cube 'knife' was short and strong, and after cutting in and locked in a fixed position, there was a brief burst of sawdust in the warehouse;

After that, the blade tooth rotates the turntable of the control slide rail again, and drives the three-jaw chuck to move back and forth at a speed that is neither fast nor slow.

The sawdust flew again, and in the regular movement of the three-jaw chuck repeatedly forward and backward, the log quickly became thinner and rounder under the action of the 'knife'.

When the steps are almost completed, the blade leaves the station and removes the 'shaft' for inspection;

On a cursory look, it looks fairly straight;

Then, he held it flat and turned it at the light source at the door for further inspection....

The results are very good, the shaft is straight, the curved surface is smooth, and it is no problem at all.

Nodding with satisfaction, the blade returned to the station and began to work on the 'machine'.....

He has tried to manufacture a variety of workpieces such as gears, and the finished products are all flat and smooth;

The difference between the same workpiece is not as good as that of magic;

However, the error rate is also limited to a certain acceptable, even excellent, range.

Put all the artifacts on the ground one by one, and let the apprentices, who were almost stunned by the spectators, come forward to check it;

After that, Blade Fang spoke,

"This is the machine I want you to design, and I would like to call it a 'machine tool';"

"The one in front of you has three functions: 'saw', 'car' and 'boring', whether it is 'saw blade' or 'turning tool' and 'boring cutter', all of which use the most cutting-edge 'three-level strong steel wood' of the tribe today, and can be replaced according to the size of the workpiece."

"As for the gears and other components, the 'three-grade tough steel wood' is chosen, which can also be replaced according to the situation."

"Whether it's the strength of the processing end or the durability of the body, it is enough to support the processing of any material below 'grade 3'."

"In other words, whether it is 'first-class steel wood' or 'second-class strong steel wood and tough steel wood', or any known natural wood or stone, it is within its scope of work."

"But remember, your goal is not to operate it to make parts for assembling boats and wheelbarrows; Rather, it is used to manufacture the standard parts of the next 'machine tools' that you will later design. ”

"Remember what I said by 'standard', and see the 'scales' on these turntables?"

Bladetooth led the trolls who were looking at the finished parts to the machine console, and pointed to the 'steering wheels' on the case.

"See..."

"This is the essence of the 'standard', the error of the final product will be affected by the accuracy of its upstream and downstream processing chain;"

"If this is a 'mother machine', and it has a machining accuracy second only to magic;"

"Then what you want to design and manufacture is a 'sub-machine'.... Its machining accuracy and strength will inevitably drop by one step; ”

"And in the future, if the processing chain is extended again, it will derive the 'submachine of the sub-machine'...... Wait, then this accuracy gap may be further magnified. ”

"In order to minimize the impact of this and to ensure the replaceability of the parts..... We must do a good job of error control at the top of the processing chain, and strictly design and implement the manufacturing standards of each workpiece. ”

"Do you understand?"

The trolls nodded their heads, indicating that they understood the causal connection.

"Of course, it's too early to talk about 'design', and the first thing you need to do is to study the working principle of this 'mother machine'."

"This so-called 'principle' is not a 'method of use', but a more fundamental operating logic within it."

"For example.... You come here, you look here..."

Bladetooth pointed to an area composed of multiple sets of gears that bite each other, "Why do these gears transmit the power of my pedaling to other places?" ”

"What role does the size of the force, the position of the arrangement, the direction of the occlusion, and even the spacing of the 'teeth' play in the transmission of force?"

"And here..."

As he spoke, he grasped an operating panel in his hand and slowly turned it 45 degrees;

A 'crunch' sound came from the processing table, but it was the slide that moved forward several meters.

Only then did Blade Fang stop what he was doing and continued,

"I'm here, obviously I only let the turntable rotate so far away, why does it have such a large displacement at the action end?"

"And these 'crunching' noises, it's annoying, right?"

"Why is this sound happening? How can it be reduced, and can it be avoided completely? ”

"What can we do if we can avoid it; If it's inevitable, then why. ”

"These are the things you should be exploring now;"

"Only when we have mastered them, when we encounter difficulties in this aspect in our lives and work, can we think about 'why';"

"And use this knowledge to further think about 'how to solve it'."

"And the thinking of 'how to solve it' is the starting point of what I think of as 'design'."

"In addition, if you make great progress in thinking about the 'principle', you will have the opportunity to present it at the Witch Doctor Conference;"

"Also, remember your previous experiences at 'school'? The ones you remembered, the clay tablets that say 'mathematics' and 'physics' on them, right? ”

"'Uniform motion theorem of blade teeth', 'Blade teeth binary equation'...... My name will be remembered by the tribe forever and forever with this knowledge; ”

"If you have made achievements in the field of 'mechanical principles,' then your name will also have this honor from now on."

~~~~~~~~~~

The machine was carried away by the apprentices and the teeth of the ship who wanted to get involved anyway;

Such a huge thing, even with their physical strength, took dozens of trolls to succeed.

The tribe now has so many strongholds, and the number of apprentices is nearly 100, just such a machine tool is not enough.

Even if you don't ask for it, you don't need to have every base, but in the headquarters and the largest base at your feet, at least a few machine tools with different functions need to be equipped to be enough for them to study.

Therefore, the blade tooth has to work overtime here to build a few more; Later, when I return to the tribe, I will have to continue to do this again.

Since then, the function of the machine tool has not been so troublesome as the 'three-in-one' that continues to be integrated, and it is enough to have a few more single functions.

As for what kind of functions are equipped..... He doesn't know much about machining, and for the time being, he only thinks of a limited number of "boring", "turning", "sawing" and "ball milling".

As for the other functions in the future, let the specific researchers slowly find and ponder.

After this research, Bladetooth has no intention of meddling further.

The tribe was always in the stage of development, and if he wanted to, there was a lot of work that could be done in all aspects.

But Blade Tooth is not a nanny, and he can't be a doppelganger, so he can't take care of the progress of so many projects at the same time.

Therefore, choosing to let go after giving the relevant direction may be the best choice to retreat.

~~~~~~~~~

Bladetooth spent more than a month at the original site of the Gabi Division, during which time he not only participated in the further construction of the station, but also built several single-function machine tools, which were happily moved by the apprentices who were counting on the 'history of history'.

In addition, negotiations between the three ministries have been reached, and a preliminary decision has been made to carry out the transfer of prisoners at the so-called 'holy mountain' after 80 days and nights (two months), as well as further discussions on the future of the quadrilateral relations.

The three tribes have lost this group of strong laborers for a long time, and the status quo of the tribes is precarious; It is only by relying on the food stored in the 'sacred mountain' for many years that he can barely survive.

Therefore, they are not willing to wait any longer, preferring that their teeth come over and negotiate sooner;

For this reason, even if you pay more 'fines', you are willing to do so.

But their appeal was rejected by Bladetooth, and he decided not to limit the 'talks' to the extent of the participation of the 'Quartet', but to go further and turn it into a conversation between the entire Black Forest tribes.

Originally, he didn't plan to do this, but after thinking about it, he realized that this was indeed a great opportunity.

Whether it was the previous disposition of the Cabebes, or the earlier victory over the three tribes;

Once it cooperates with the arrival of a large number of prisoners escorted this time, it will definitely be a great deterrent to the troops.

In order to take advantage of this more effectively, Bladefang will send an apprentice to act as a 'messenger';

Dressed in the most splendid garments of the tribe and holding clay tablets with the 'Invitation' written on them, they will set out to the east, south, and southeast to convey the will of their headquarters to the chiefs and witch doctors of the Black Forest.

The tribes will be required to send all the old witch doctors, old apprentices, and chiefs of their respective tribes, plus at least one other powerful troll who has the power to speak;

They were allowed to arrive at the 'Holy Mountain' on their own within sixty days and nights and waited, and they did not wait until the time was over.

Otherwise, the next time I visit, it will be an army of teeth.

Not long ago, the wolves tracked down a herd of moose and led the tribe's hunters to sweep them all;

The apprentices who are responsible for taking care of the moose herd have also figured out the concept and method of 'desensitization training';

Taking advantage of the previous free window, the tribe once again expanded the size of the army, of which the number of cavalry troops has reached one hundred and two.

This time, these new and old cavalrymen can just act as escorts for the envoys' trip.

But in between, there is another issue that needs to be solved.

This time, Blade Fang has been given arbitrary power in the Parliament, and will be fully responsible for the follow-up of the three departments.

But this time, his general trip has gone beyond the scope of three departments, and it concerns the entire Black Forest tribes.

In any case, this is not within the scope of his mandate...... If it is arbitrary, it is a complete arbitrary act.

Blade Fang asked himself if he was a good troll and a good witch doctor who led by example, so naturally he wouldn't just do it on his own.

In order to solve this hidden danger, he used magic to weave a large sail with the assistance of the ship's teeth;

And according to the existing parameters, it took five days to build an ultra-small fast galleys with magic.

The new ship abandoned most of the oars, and in order to speed up construction, it also greatly reduced its own tonnage, and further narrowed and long.

There is also a mast hanging high above it, on which are hung large sails with a concave streamline, which allows the boat to eat enough wind power in both windward and upwind conditions.

At certain angles, a ship with such sails can sail against the wind even faster than the wind itself.

It is a pity that the topography and wind resources of the Black Forest do not give it full leeway;

The ideal stage has to be the sea.

However, even so, thanks to the combined effect of the sails and the smooth water, the fast galleys were able to bring back to the headquarters several clay tablets with the blade tooth proposal written on them at great speed.

The return journey wasn't that fast, but after picking a good day (not necessarily a good one), it was quite efficient in bringing a new 'authorization' to the council chamber and a supplementary notice for the number of troops.

He was accompanied by another group of apprentices who would serve as messengers this time.

Food, grass, new clothes, new weapons, and authorizations were all in place, and at this opportunity, the mission composed of 120 cavalry + 20 apprentice messengers quickly set off from the station.

They will first divide into two groups, half of which will go south to the three regions, using that as a base, and then go to the surrounding tribes in groups.

The other half will continue eastward by boat, and will dock separately depending on the destination.

The Jabes were close to the three regions, and the large number of troops led by Bladefang could reach it in less than five days, so he had plenty of time to prepare.

Since it was a deterrent operation against the 'high-level' of the entire Black Forest Ministry, the earlier plan was no longer feasible, and a larger-scale mobilization of soldiers and hunters was necessary.

In a recent expansion, in addition to the cavalry being added to a full brigade, a battalion of arrays was also added;

The total scale has thus reached: two brigades of array soldiers + one brigade of cavalry, a total of 375 soldiers.

In addition to their full participation, the council also decided to send an additional 40 squads of hunters, a total of 400 trolls, to serve as hunters to make a name for themselves.

For the headquarters, which has a total 'human' population of just over 3,000 (not counting the three female prisoners), this level of troop dispatch is enough to feel the pressure.

For this reason, the size of the hunter team in all the stations will be reduced, leaving only a limited force to protect the warehouse;

At the same time, the headquarters will also reduce hunting activities and concentrate its efforts just in case.

However, the relative quantity is stretched, and the pressure on warehousing is not great;

Over the years, the trolls have been stockpiling up all kinds of meat and plant food like hamsters, and the ice storage is almost always full.

The size of the fruit grove is also expanding year by year, and it is common for all witch doctors to add a few fruit trees during breaks.

This operation should be regarded as relieving the pressure on the hunting grounds, and by the way, depleting the earliest part of the food stock..... After all, the age of some warehouses can be traced back to a long time ago.
