08 years ago.

The quantity of material preparation of the product is obtained by dividing the total plate area by the area of the large plate, and then the total number is calculated according to the utilization rate of each component.

For example, for a cabinet with a total area of 200 square meters, when calculating the plates, divide 200 by 2.97 (the area of the large plate) to get 67.34 sheets.

Then calculate according to the utilization rate of 88% of the cabinet.

67.34 divided by 0.88 = 76.5 sheets.

As a result, this order requires 76.5 large boards.

After providing 76.5 large slabs for the masters, each master calculates how to cut the material optimally.

Often because of the different levels of the masters, the final results are also different, some people are just enough, some people can save a few, and some people are not enough.

At present, in addition to some large enterprises with software, the software can automatically optimize the typesetting and obtain the maximum utilization rate of the board.

In most factories, the calculation and operation of cutting materials are still carried out by manual calculation.

There are two factors that affect the utilization rate of plates.

One factor is the parameter setting of the product itself, and the other is the level of typography calculation of the master.

After Liu Wei joined Hutao Group, he got the drawings of the model room as soon as possible, and he was waiting for the materials during this time.

He and a few apprentices spent the day in the dormitory researching how the products were prepared.

When the personnel were hired, he learned about the personnel information with the administration.

When he learned that only one of their teams was from Yapai's household, he had a hunch that the cabinets in the project would be produced by their group.

Sure enough, when I got the production task list last night, the product on it was a cabinet.

He and a few apprentices studied the latest drawings last night.

They were pleasantly surprised to find that the core parameters of the cabinet were optimized.

First of all, the depth of the wall cabinet is 330mm, and the depth of the base cabinet is 540mm.

If you are a layman, you will definitely not be able to see the content, but as a master who has been producing cabinets for ten years, Liu Wei immediately saw the mystery.

First of all, a large board is 1220mm wide and 2440mm high.

During production, because there was a chipping on the edge of the slab, it was necessary to cut off 5 mm on both sides, so that the width was 1210 mm.

Because the thickness of the saw blade is 5mm, if you open two plates, it is 1210-5=1205, and then divide by 2, the two largest plates are 602.5mm in theory.

If you open three plates, it is 1210-10=1200, and then divide by 3, the theoretical maximum value is 400mm.

The size of the cabinet is 330mm and 540mm, so open it by three pieces, just right.

1210 (overall width) - 10 (double saw pass) = 1200mm

1200-540=660mm

660/2=330mm

So a large board, cut two 330mm and one 540mm board, just used up.

In the real kitchen, the wall cabinet will generally be shorter than the total length of the base cabinet, often the wall cabinet is only 2.4 meters, and the base cabinet is about 4.2 meters.

Therefore, in this way, the wall cabinet part and the base cabinet part can be combined to perfectly open the wall cabinet part.

Some novice cutting masters are often separated, the floor cabinet opens the ground cabinet, and the wall cabinet opens the hanging cabinet.

That's a lot of wasted plates.

For example, when the wall cabinets are opened together:

330 times 3 = 990mm

1210 minus 10 minus 990 = 210mm

The remaining 210mm can only be used to open the pull plate, but in the cabinet, except for the base cabinet with front and rear pull plates, other cabinets are not.

So in the end, a lot of this strip material will be left.

Statistically, the number of plates wasted in the end is definitely not a few.

By Utilization:

990 divided by 1210=0.81%

If the material is really cut in this way, it is equivalent to only 81% of the plate utilization.

With a depth of 540mm, a large board can open two pieces.

1210-540=670，670-540=130mm

130mm can open two pull plates with a width of 60mm, just used up.

If the wall cabinet and the base cabinet are combined, the plate parts required for the wall cabinet are produced first, and then the base cabinet is produced separately.

Then the number of plates required must be the lowest.

Another factor that affects utilization is the height term.

The height of the sheet is 2440mm, and after cutting off the edges, 2430mm remains

If the height of the wall cabinet is set to 600mm or 800mm, then the panels can be used perfectly.

600*4=2400mm

800*3=2400mm

The former has three saw paths and removes 15mm, while the latter has two saw passes and removes 10mm.

When added up, they are all in the 2430mm range.

The floor cabinet height is set to 680mm.

700*3=2100mm

2430-10-2100=320mm

The remaining 320mm board is just used to make the shelves of the wall cabinet.

The cabinet parameters set in this way can be said to make perfect use of materials.

Liu Wei has calculated with several apprentices, and the utilization rate of the plate has reached an astonishing 98%.

This means that there is a positive difference of 10% between the preliminary 88% and 98%.

How scary is that?

At the end of the year, there were a total of 20,000 sets of cabinets, and 12,400 sets were left in the factory, which were calculated according to 2.4-meter wall cabinets and 4.2-meter floor cabinets.

The wall cabinet is 2.4 * 0.8 = 1.92 projections

The base cabinet is 4.2 * 0.7 = 2.94 projections

According to the formula, the wall cabinet is 1.92 * 3.2 (coefficient) = 6.14 unfolded area.

The base cabinet is 2.94 * 4.2 (coefficient) = 12.35 unfolded area according to the formula.

6.14 + 12.35 = 18.49 square meters.

18.49*12400=229276 square meters

229276 divided by 2.97 (large board area) = 77,197 large plates

77197 divided by 0.88 (utilization) = 87724 large boards.

If calculated as a saving of 10%.

77197 divided by 0.98 = 78772 large boards

87724-78772 = 8952 large boards

A large board is 185.7 yuan.

8952*185.7=1662386.4 yuan

It's really not that I don't know, I'm shocked, even if the data is discounted in half, and 4,500 big boards are saved, it is 830,000 yuan.

At the meeting, Mr. Wei promised that some of the masters who saved would take 60%.

60% of 830,000 yuan, equivalent to 500,000 yuan.

After Liu Wei and several apprentices finished calculating, they looked at each other, and some of them who did not believe in evil continued to count three more times.

In the end, everyone's lips and hands were shaking.

Without mentioning the price, let's just say that the 500,000 yuan is divided into a 75-day production cycle, which is almost 6666.66 yuan per day.

Not only is it an unbelievable coincidence, but it is also incredibly panicked.

Several people looked at each other, and the most active apprentice tried to open his mouth several times, but finally fell silent.

In the end, Liu Wei made a final decision: "Since the rules are like this, it is our ability to abide by the rules and get the remuneration allowed by the rules."

"If the company keeps its promise and really sends down 500,000, I will take 230,000, and the remaining 270,000 will be 90,000 yuan each."

"If the company is only a symbolic reward, then if it does not exist, in any case, it cannot damage our mentorship and apprenticeship."

"Do you hear that?"

At the end, Liu Wei's sentences were serious and cold.

"Yes, Master."

The three apprentices all nodded to show that they basically did not report hope for the 500,000 yuan, and in this case, the company had a reward of 50,000 yuan, which was already very kind.

It is also good to reward 5,000 yuan for one person.

On the first day of today, all the machines are basically a combination of master and small worker.

8:10

The material preparation frame under the first supporting plate is pushed to the pneumatic lifting table on the left side of the cutting saw through the drum line.

Originally, 120 large slabs were supported during transportation, but after the differentiation of the warehouse, it became 60 large slabs and one pallet.

Mainly for the convenience of transportation and storage in the factory, the height of the 60 large slabs is 1.08 meters.

The height of the sliding table saw is exactly 1.1 meters.

After stepping on the foot valve of the pneumatic lifting table, the plate slowly rises, and stops when 6 large plates exceed the height of the saw table.

Liu Wei and the workers carried the boards to the sawing table one by one.

After lifting 4 pieces each time and aligning the plates, Liu Wei fixed the 4 large boards and pushed them onto the saw blade.

"Squeak! …”

Cut 5mm of the edge first.

The worker waited on the other side of the saw blade, because it only cut 5mm, and the thickness of the saw blade was exactly 5mm, so there was nothing but debris.

After the edge is cut, pull the saw table of the sliding table saw back to the original point, and push the plate towards the right side of the saw table to the pallet with a distance of 330 mm.

The first lump of plates was officially opened.

"Squeak! …”

The imported motor, coupled with the diamond saw blade, is very powerful, and the process of pushing the plate is silky and unhindered, and the plate is cut through in less than 20 seconds.

The worker in front right saw that the plate was cut, he took the 330mm part, moved it forward, and then moved it to the right to let the plate leave the saw blade.

After Liu Wei pulled the saw table back to the original point, he also came to the right side, and lifted four 330mm wide boards to the pneumatic elevator on the right side with the small worker.

The second time was to cut 330mm, and after repeating the previous operation, the two lifted 4 330mm boards to the lift again.

Next, the worker pushes 8 sheets of 330mm through the drum line to the empty shelves.

This is the advantage of having a drum line and a stock shelf, otherwise, the plates can only be stacked on the spot.

After Liu Wei pulled the sliding table saw to the origin, he flipped the remaining four large slabs so that the other side faced the saw blade.

After aligning the plate to the size of 540mm, Liu Wei pushed the saw table for the last time.

"Squeak! …”

Pushing to the head, Liu Wei restored the saw table to its original point, and the worker just came back, and together with Liu Wei at the other end, he lifted the 540mm board to the lifting table on the right side.

At this point, the first lump of plate cutting is completed.

To sum up, it is to lift the plate, cut the edge, open 330mm twice, flip and cut the edge again, and just 540mm remains.

The worker needs to help carry it three times, once to the stocking shelf.

2 minutes for a single cutting operation.

120 boards are opened in an hour, and 1200 boards are opened in 10 hours in a shift, which is only the time to open longitudinally.

After storing enough longitudinal plates, they can be used to cut the transverse, and after cutting the transverse, they will become parts and can be transferred downward.

The general aspect ratio is 4:6.

After 4 hours of longitudinal panels, it takes another 6 hours to open the transverse.

Because at two o'clock this afternoon, the edge banding line was turned on, so in the 5 hours this morning, Liu Wei could only drive 2 hours longitudinally, and then it took 3 hours to open the horizontal and open the board into parts.

It is expected that 240 large boards can be opened this morning.

240*2.97=712.8 square meters.

712.8 * 1.5 (wages) = 1069.2 yuan.

After earning 1,069 yuan in one morning, and after the small workers divided 150 yuan, Liu Wei still had 900 yuan left.

After working another 6 hours in the afternoon to change shifts at 20:30, Liu Wei is expected to earn 2,000 yuan.

If you add the saved reward of 6,666 yuan, it is equivalent to a daily salary of 8,666 yuan.

It would be too false to say that the heart is not hot.

But Liu Wei has always been conservative, let's just count it as a daily salary of 2,000.

60,000 a month, more than 100,000 at the end of the year, it shouldn't be a big problem.
