The drilling machine is a popular type of mechanical machine which is used to drill holes in the material. There are many components in the drilling machine. They are motor, table, column, chuck, spindle… The basic operation process of a drilling machine consists of 6 steps. Step1, in this step you need to perform a safety check before turning the drilling machine on. Beside, wear ear protection if drilling regularly and wear safe clothing and eye protection. Step2, Choose the correct drill bit and fit the drill bit firmly into the chuck.  Make sure the bit is straight and secure before you turn on the drill. The Preparation process is finished. Next to Step3,  turn on and operate the machine. You need to drill a pilot hole before drilling to an exact dimension. The pilot hole will help prevent your drill bit from slipping. You should drill with steady pressure during the drilling process to avoid fracture the drill bit. Be careful! If you drill at high speeds or regularly you should slow down to avoid overheating the drill bit. Step4, You turn off the machine, and you need to clean and  maintain it  after operating.  This is to ensure the durability of the machine.

This 20-volt heavy-duty cordless drill DeWalt DCD991P2 is one of our best performers. DeWalt DCD991P2 is a popular type of cordless drill which is used to drill holes and drive screws into surfaces. DeWalt DCD991P2 comes with a lot of features that you wouldn’t expect on a model at this price point. It comes with good power, snagging top ratings for power, speed, and run time. This DeWalt drill is equipped with three speed settings. It’s also a low-vibration unit, which means your holes will always be high-quality. A built-in LED light helps illuminate your workspace.  Plus, it goes for half the price of many cordless drills with similar capabilities, while still proving to be reasonably powerful. However, It’s also some cons. Compared to stationary drills, DeWalt DCD991P2 may not have the same level of power. If you’re working on larger projects, you may need to recharge or swap batteries frequently. All cordless drills have pros and cons, so we need to choose a versatile and practical cordless drill, which depends on the task at hand.

INCIDENT REPORT

1. EMPLOYEE (S) DETAILS:
Name: Hoang

Sex: Male
Age: 23
Department attached: Maintenance
Length of time on present job: 2 months
2. DESCRIPTION OF THE INCIDENT:
Date: 19 March 2025
Time: 1.20 p.m.
Location: Production line No.3 in General Assembly
Equipment involved: Conveyor belt
Injury: Left hand
Details:
Hoang had switched off the machine and was conducting routine checks on the conveyor belt. He saw that one of the connections was not good. He started to change it when Nam switched the machine on. The conveyor belt moved and Hoang’s left hand was caught in it. His hand was seriously injured. There were no witnesses to the accident. However, Tien, who was working nearby, heard Hoang’s yell and ran to his aid. On seeing Hoang’s injury, Tien ran to get the first aid kit. Meanwhile, Nam called the immediate supervisor. Tien wrapped the injured hand in a loose bandage and Nam called for the ambulance.
The ambulance arrived at 1:40pm. Nam was taken to the FPT  Hospital. Dr. Binh did an X-ray and found that all the fingers on Hoang’s left hand were fractured. Hoang’s fingers were placed in a cast and he was advised to remain at home for at least 2 weeks.
3. CAUSES:
After an initial investigation, I discovered that step 19 of work procedure no. 2 was not followed. The procedure requires that a “Work in Progress” sign board be displayed when conducting any repair or maintenance work.
4. RECOMMENDATIONS
To prevent similar occurrences, I suggest the following :
- A refresher course on safety procedures should be conducted.
- Details of the person/s to contact in the event of an emergency should be displayed.

Write a paragraph (120-140 words) about what a mechanical engineer can do to help save the planet Earth.

First and foremost, in my daily life, I can help save the planet by using energy-efficient devices and reducing fuel consumption in my daily life. For example, I can choose to ride an electric bike or car instead of a fuel-powered vehicle, which reduces air pollution. Furthermore, I can save water by using it efficiently, plant more trees to improve air quality, and limit plastic waste by using reusable products. Besides, I can recycle materials and reduce waste at home, which helps protect the environment.

In my job, I can focus on designing machines that consume less energy and produce fewer emissions. Last but not least, I can apply computer automation to improve accuracy and reduce material wastage, and promote the use of eco-friendly technologies like electric cars and modern welding methods. Together, these actions can help create a greener and healthier planet.

Write a paragraph (120-140 words) to describe a device or machine that uses alternative energy to protect the environment.

One device that uses alternative energy to protect the environment is the solar water heater. This machine utilizes solar energy, a renewable and non-polluting source, to heat water for domestic use. The system consists of a flat plate solar collector, a storage tank, connecting pipes, a pump, and a controller. The solar collectors are typically installed on the roof or open ground, where they absorb sunlight to heat water, which is then stored in a tank. The heat remains in the tank, keeping the water hot overnight. The main advantage of this device is that it saves electricity and reduces energy costs. However, it cannot be used without sunlight, and it requires regular maintenance, such as repainting every 2-3 years. Despite these drawbacks, solar water heaters offer a sustainable and cost-effective solution for reducing energy consumption.

Write a paragraph (120-140 words) to describe one device/machine using smart technology applied in a specific field (IT, medical, transports….)

One impressive device using smart technology is the assisted-living wristband. It is mainly applied in the medical field to help monitor elderly or sick people living at home. This smart device is worn on the wrist and collects important health data like movement or location. It can detect if the person has fallen or left a safe area. The wristband connects with a smart home system, like the InterHome project, which stores the user’s living patterns and adapts to improve energy efficiency. This device benefits people by providing safety, independence, and peace of mind for both the elderly and their families. It helps solve problems like unnoticed falls, wandering, and reduces the need for constant human supervision. Most importantly, it supports, rather than replaces, existing care services, improving overall quality of life.

Write a paragraph (120-140 words) to describe a smart house that you want to live in the future

I would love to live on a smart house located in a hillside. This house would be equipped with advanced Samsung smart technologies, such as the Bespoke AI Jet Ultra vacuum, which would keep my home clean effortlessly, and smart thermostats to regulate the temperature for maximum comfort and energy efficiency. The house would also have an integrated smart lighting system, security cameras, and automated blinds, all controlled by voice commands or my smartphone. The main advantage of living in such a house is the convenience and energy savings it provides, while also contributing to sustainability. A disadvantage might be the potential privacy concerns and technical malfunctions. I would live in this house with my family, as it would enhance our daily life. I want to live here because it combines comfort, innovation, and eco-friendliness.
