Because I was considered half a junior high school student at that time, plus I was not old enough to work. After the boss learned about it, he considered that the labor law at that time prohibited the use of child labor. According to the Labor Law, the requirement was to be at least eighteen years old. However, the Civil Law Notice stipulated that those who had reached the age of 16 and used their own labor income as their main source of income were regarded as people with full capacity for civil conduct.
It was a mandatory rule to protect the rights and interests of young people. There was a contradiction between the two laws. However, if you went to work in a private enterprise, the requirements would not be so strict. As long as the employer agreed to take you in, you could work. If you want to work in a state administrative agency or institution, they generally won't accept you!
The state forbids the use of child labor. Child labor refers to teenagers and children under the age of 16 who have a labor relationship with a unit or individual and are engaged in labor with economic income or individual labor. However, teenagers and children under the age of 16 who participated in family labor, work-study programs organized by schools, and auxiliary labor that was not detrimental to their physical and mental health and within their ability were not considered child labor.
Moreover, after using it, a load will be found: Under normal circumstances, the labor administrative department will order it to correct and impose a fine.
According to article 94 of the Labor Law of the People's Republic of China, if an employer illegally recruits a minor under the age of 16, the labor administrative department shall order it to correct and impose a fine; If the circumstances are serious, the business license shall be revoked by the administrative department for industry and commerce. If the circumstances are serious, they shall be convicted and punished in accordance with the Criminal Law of the People's Republic of China.
According to the sixth article of the Regulations on the Prohibition of Child Labor, if an employer uses child labor, the labor security administrative department will impose a fine of 5000 yuan per month for each child labor. Those who use child labor in the workplace where toxic substances are used shall be severely punished according to the range of the fine stipulated in the Regulations on Labor Protection in the Workplaces Where Toxic substances are used, or according to the standard of a fine of 5000 yuan per month for each child labor used. The administrative department of labor and social security shall also order the employing unit to send the child laborer back to his original place of residence within a time limit and hand him over to his parents or other guardians. All the transportation and accommodation expenses required shall be borne by the employing unit.
The legal basis:
"Labor Law of the People's Republic of China", article 94
If an employing unit illegally recruits a minor under the age of 16, the labor administrative department shall order it to make a correction and impose a fine; If the circumstances are serious, the business license shall be revoked by the administrative department for industry and commerce. If the circumstances are serious, they shall be convicted and punished in accordance with the Criminal Law of the People's Republic of China.
About a week after I stayed, I was sent to the best school in Qingzhou City Weifang City. The first thing to learn was the basic knowledge, just like learning Mathematical Olympiad. It was especially simple and crude at the beginning, but it was simply not learned later on.
For example, a numerical control machine tool, process:
1. Turn on
The steps to turn it on were as follows:
1) Start the air pump (a numerical control machine tool that uses air pressure to tighten the tool);
2) When the air pressure reaches the specified value, turn on the main power supply of the machine tool;
3) Press the Poweron button on the system panel to enter the system start-up state;
4) After the system is started, observe whether there is an alarm on the display. If there is an alarm, press the MESSAGE button to enter this page to see the alarm information and cancel the alarm before proceeding to the next operation of the machine tool. For example, if the alarm displayed was Emergencystop, the alarm could be removed by rotating the emergency stop button clockwise. The alarms that appeared when the machine tool was turned on were not only the emergency stop, but also the low level alarm of the cooling liquid and the low level alarm of the hydraulic oil. The corresponding measures needed to be taken to remove the alarm.
2. Return to the reference point
This was a necessary operation after the machine was turned on in order for the numerical control machine tool to find the benchmark of the machine tool coordinates. The steps were as follows:
1) Press the BOSS button, select the comprehensive option, and observe the machine coordinate value to see if it is less than-100. If not, you need to select the Jog to manually move the coordinate axis until the value meets the requirements before proceeding to the next step; If the requirements were met, the next step could be directly carried out.
2) Choose the REF gear, press X, Y, Z, and then press HOMESTAR to start the zero-return. After returning to zero, the LED display interface shows that the zero-return action is completed;
3) After returning to zero point, it is necessary to exit the zero point in time to avoid pressing the travel switch for a long time and affecting its life. Press the Jog to select each axis to move away from the zero point in the opposite direction;
" Note: Sometimes, after pressing the emergency stop button, the machine tool lock, the Z-axis lock, and the idle operation button, the machine tool must return to the reference point again. Otherwise, the machine tool system will lose its memory of the zero point of the machine tool and cause an accident.
3. Method of displaying coordinates
The coordinate button on the LCD panel of the numerical control milling machine was the BOSS button. There were three kinds of coordinates on the display interface, namely comprehensive, absolute, and relative. The following is an explanation of each coordinate form:
1) The function of relative coordinates. First, it can be reset or set the coordinate value at any position of the machine tool, which plays a great role in the pre-setting of the coordinate point during the tool setting operation. Secondly, the relative coordinates also allowed us to reset any point where the machine tool stopped when we operated the machine tool, making it convenient for us to calculate the distance of the moving axis.
The operation steps for zeroing were as follows:
a. Press the BOSS button to display the coordinates;
b. Choose the relative coordinate display mode;
c. When the X axis is reset, press the X button. At this time, the "Origin" will flash at the bottom of the LCD screen.
d. Press " Origin ". At this time, the X-axis is cleared. Similarly, the Y-axis and Z-axis are cleared.
2) The function of integrated coordinates can display the changes of relative, absolute, and mechanical coordinates at the same time. Here, the emphasis was on the mechanical coordinates: The "machine tool coordinates" were the coordinates of the machine tool relative to the machine tool origin. Its first function was to check whether the "machine coordinate" was zero when the machine was reset to zero. If it was zero, it meant that there was no problem with the machine tool being reset to zero. The second was to move each axis to the maximum travel position of the machine tool, which could directly display the travel of the machine tool.
3) Absolute coordinates are used to determine the coordinate origin of the tool relative to the work piece. It is mainly used to remember the coordinate value when the tool is set. The work piece origin of the tool is recorded in any one of G54-G59. The steps to use the absolute coordinate system were as follows:
a. When the tool is at the zero point position with respect to the three axes of the work piece, the origin should be recorded in the relative coordinates first, that is, the relative coordinates of the three axes should be reset at this time.
b. Press the OFFSET button, select the coordinate system, and enter the absolute value coordinates G54-G59. Here, we choose the G54 coordinate system.
c. Enter X0 to measure. Similarly, measure the Y and Z axes. At this time, the origin of the work piece is recorded in the coordinate system G54. When programming, you only need to call the G54 coordinate command.
4. Axis movement operation
There were two ways to manually move the various axes of the numerical control milling machine: The first was in the Jog mode, and the second was in the Handle mode.
1) Move the coordinate axis in the Jog mode
a. Choose the Jog gear and enter the Jog mode;
b. Choose a moving axis and direction from-X, X, -Y, Y, -Z, Z;
c. Manual control of the rotation button, FCEDRATE OVER RIDER, can change the speed of the axis movement (the speed at this time is the F speed adjustment of G01);
d. After determining two very long distances, we should reach the destination as quickly as possible. At this time, adjusting c cannot reach the speed we want. Here, we need to use fast movement to adjust the speed: F0, 25%, 50%, 100%. Generally, when learning the numerical control milling machine, choose 25%, then select the axis and direction of movement and press the accelerator key. The axis will move quickly.
2) Move the coordinate axis by hand wheel
a. Choose the Handle gear and enter the Handle mode;
b. Choose the gear of the axis you want to move (Off, X, Y, Z, A), and then select the feed speed (X1, X10, X100);
c. There are generally two types of handwheels produced by different manufacturers. One is a handwheel switch, and the other is no handwheel switch. If there is a handwheel switch, you have to press the switch when you use it. If there is no handwheel switch, you can use it directly.
d. Then rotate clockwise to move the shaft in the positive direction, and counterclockwise to move the shaft in the negative direction.
Note: The positive direction of the X and Y axes of the numerical control milling machine is opposite to the Descartes coordinate system, and the Z axis is the same as the Descartes coordinate system (used in the case of manual movement of the axis). The editing program would input the coordinates according to the Descartes coordinate system.
5. Spindle rotation
There were two ways to rotate the main axis. One was the MDI mode; The other was the manual mode. However, the Fanuc system's numerical control machine tool could not make the main axis rotate forward and backward manually after it was turned on. It had to give the main axis a reference speed in the MDI mode before the manual mode could make the main axis rotate forward and backward.
1) MDI Method
a. Choose the MDI mode;
b. Press the 'Prog' button;
c. Enter the forward rotation command and speed of the main shaft, such as " MO3S800;”;
d. Press the END button to input the data;
e. Press the CycleStart button, and the main shaft will rotate forward;
f, adjust the speed of the main axis to rotate the button, so that the rotation pointer is 100%, that is, the current speed is 800r/min, if the rotation pointer is 50%, the current speed of the main axis is 400r/min;
g. Enter the M05 command in the Prog interface, and the main axis will stop. The same steps can be used to reverse the main axis (the reverse of the main axis is generally used when tapping the thread of the numerical control machine tool).
h. You can also choose the Jog mode and press the stop button of the main shaft, and the main shaft will also stop (this method is commonly used).
2)Jog
The prerequisites for this operation were: After turning on the machine, the speed had been set using the first method.
a. Choose the Jog gear and enter the Jog operating environment;
b. Press the main axis forward/reverse button (select one), and the main axis will realize forward or reverse rotation;
c. Use the main shaft speed adjustment button to adjust the main shaft speed (the adjustment range is 50%-120% of the given main shaft speed);
d. Press the Spindle Reverse button to stop the Spindle.
6. Knife installation

Of course, I still became a " university student " despite living such a life. I studied honestly, but I can't always be honest. There are seven days in a week, and I go back to the company on weekends to practice. I can do anything I want, such as the back of the car, opening the groove, pressing the plate, drilling the hole, etc.
Later on, he made a fuss about wanting to be a top-notch photographer from an aristocratic family and ended the show.
