Milling is the process of removing material from a workpiece. The milling process is flattens, thins, warps or engraves the workpiece. The milling machine consists of the following main parts: main shaft, working table. To use the milling machine safely, we need to follow these steps.
- Step 1: Wear protective clothing
Wear protective clothing, shoes and goggles to protect ourselves from debris while the machine is in operation.
- Step 2: Fix the workpiece on the workbench, insert the knife into the main shaft.
We will tighten the workpiece on the workbench and the knife on the main shaft to ensure that when the machine is working, the workpiece will not be thrown out.
- Step 3: Check the milling machine and start
Check the power to the machine, set the cutting speed and turn on the start button
- Step 4 Adjust the working table for machining.
When the milling machine is working, the main shaft is stationary and the working table can be adjusted to the X, Y and Z axes by turning the handle on the machine.
- Step 5 Cool the workpiece
When the milling machine is in operation, the friction between the tool and the workpiece will increase the temperature and heat the tool leading to tool breakage, so an oil cooling solution must be used.
- Step 6 Is over
After processing is complete, turn off the machine, take out the product and clean the machine

One of the most important tools of the craftsman is the hand grinder. Currently on the market there are many types of grinders with different models, but the most reliable is still the Bosch angle grinder. It has a few standout features. Firstly, it is compact, the weight of the machine is about 1kg, which is convenient to use and move. Second, low cost is accessible to many users. It has good stability. Finally, the machine has a capacity of 1000W to 1200W. It has an extra handle for a firm grip. With such characteristics it has a few advantages. The first advantage, it is easy to use. The second benefit, it can be used in tight spaces due to its light weight and compactness. Surprising is that it has an impressive 3-year warranty. However, it has some cons. Firstly, because it is compact, the capacity is not high. another cons, it is limited speed control when grinding at maximum. The machine is quite good when used for grinding tiles, stone, metal,... I quite like when using this machine, but what I don't like about this product is that the handle is a bit difficult to use, I hope the manufacturer develops the product to be the most complete.

I am Dung I am 21 years old. I am passionate about designing and I have been working in this field for 5 years so that is the reason why I want to apply for the position of a CAD leader in SamSung Company. As I heard before, Samsung is the top company in Vietnam with professional environment and talented people. In the past, I had a lot of experience in ABC Company where I worked before. I used to work as a mechanical design engineer for ABC Company for 3 years. I worked on designing processes which involved 3D, 2D CAD Design and BOM Management. I had been with the company for a number of years and I just wanted to experience a new environment to continue growing. At present, I am looking for a company that I can settle down and make a long-term contribution. I think that I am appropriate for your company. Actually, there are a number of valuable skills including interpersonal skills or management skills I have learnt when being a staff in ABC Company. You know, I have to work with a lot of customers and every day, I communicate with them to find down the best solutions for our products. I am also the team leader, so I have to manage to work on well with other members and assign them the work evenly. In the next five years I plan to become a leader in my field and grow with the company so I try every day to make that plan come true.

As a mechanical engineer you should not only care about your job but also try to help save the environment. Here are what you can do to protect our planet.

First of all, in the daily life, you should limit the use of vehicles using gasoline and oil Instead, you should use your foot or public transport. That would at least help the environment if you can't do any of the above mentioned.

Next, save the energy is very necessary to protect the environment what helps our save the resources to generate energy. It’s very simple such as: turn off lights, fans,… when we don’t use.

Moreover, cleaning up the environment and separating waste also make an important contribution to saving the earth. Limiting direct waste discharge into the environment.

Second is also foremost things, in the job, you need to find suitable solutions to protect the environment.. By developing hydrogen combustion engines, the emissions will be drastically decreased. Immediate solution will be use of biofuel and CNG which emits lot less pollutants than other fossil fuels like gasoline and diesel.

Next, use of solar panels for electric generation as much as possible. I know it can't entirely be a substitute of thermal power and hydroelectric power but still can be used to reduce the emissions.

Thirdly, power can be generated by using a hydrogen fuel cell which combines hydrogen and oxygen in a reactor and captures the energy of fusion as electricity.

Furthermore, another method of quick battery charging is the Nano Flow Cell technology. It combines Sodium ion (Na+) and chlorine ion (Cl-) in a reactor which generates electricity the same as the hydrogen fuel cell but the difference is here ions are used instead of full atoms. So, here literally your vehicle is running on salt water.

Last but not least,, create awareness. As a mechanical engineer, you can do some seminars in rural areas and rural schools about the use of clean fuel and avoid cutting down of trees for the cooking fuels. This campaign can have a major effect on rural development and environment degradation.

Currently with the explosion of technical technology, there are many intelligent and versatile machines that are applied in many fields such as IT,  mediacl, agriculture, life... in this article I will talk about One device that helps in human life is the smart robot vacuum cleaner. It is a great choice to help people reduce work and have time for other things. Before, we were fed up with house cleaning but now with robot vacuum it gets done quickly. The robot vacuum cleaner has many smart features such as: automatically avoiding obstacles, can suck a lot of dirt and liquid, can connect to smartphones. With just one touch, we can control the robot vacuum to work. With a compact design, it can suck every corner of the house and especially it is equipped with a safety system, ensuring safety for children. Robot vacuum cleaner is a good choice for everyone.

Nowadays with the explosion of science and technology, everything is becoming smarter thanks to artificial intelligence. Even homes are getting smarter thanks to technology. I wish to live in a smart home because it is very comfortable. My smart home is equipped with many technologies. Firstly, the house is quite large with 200 square meters divided into rooms with connected devices in the house and connected to smartphones such as lights, televisions, air conditioners, fans, refrigerators. . With smartphones we can control TV, air conditioner, lighting system. Food stored in the refrigerator will be notified to you when the expiration date has passed. Second, the house is equipped with a security camera system to make the house safer. The third house has an automatic door and is unlocked by fingerprint. Moreover, the house also has a large flower garden and a large swimming pool to help us relax after a tiring day of work. In addition, the house also uses solar energy to save electricity for the country. above is my smart home dream how about you?
