One of my favorite machines is the lathe, which is commonly used in metalworking and woodworking. The lathe’s main feature is its ability to rotate a workpiece against a cutting tool, allowing users to shape, cut, drill, or sand materials with high precision. It typically includes a headstock, tailstock, carriage, and a tool post. Operating a lathe usually involves four steps. First, secure the workpiece tightly between the headstock and tailstock to ensure stability. Second, select and install the right cutting tool depending on the type of operation, such as facing or turning. Third, set the correct speed and feed rate on the control panel to match the material. Finally, engage the cutting tool and monitor the process carefully, making small adjustments if needed. Always wear safety gear and follow safety protocols while using the lathe.

I would like to review the cordless drill, a widely used mechanical machine in construction and DIY projects. This portable tool features a rechargeable battery, adjustable speed settings, and interchangeable drill bits. Its main function is to drill holes into various materials such as wood, metal, or plastic, and it can also be used for driving screws. One major advantage is mobility—without a power cord, users can work in tight or remote spaces with ease. It’s also lightweight and easy to handle, making it suitable for beginners. However, a downside is its limited battery life, which may interrupt work if not charged in time. Additionally, it may not be powerful enough for heavy-duty tasks. Overall, I think the cordless drill is a versatile and convenient tool that’s ideal for most everyday applications.

On July 25, 2025, at 10:30 AM, an incident occurred in the CNC milling area of Workshop 2 involving Dinh Khanh Toan, a male apprentice machinist. While operating the CNC milling machine, the system suddenly shut down and released a burning smell, followed by smoke from the control panel. The apprentice quickly turned off the machine and evacuated the area, preventing further damage. Upon inspection, it was found that the machine had overheated due to poor ventilation near the control unit. Additionally, the operator had skipped a complete pre-operation check. To prevent such incidents in the future, we recommend improving ventilation around electrical components, enforcing daily inspection routines, and providing better emergency response training for all staff. This report was submitted by Tran Thi Hoa, Safety Officer of the Workshop Safety and Maintenance Department.

In return, I am more than willing to work additional hours or assist with any urgent tasks during this period to support the team.

Thank you very much for taking the time to consider my request. I truly appreciate your understanding and support.

In the future, I want to work as a mechanical design engineer for an innovative manufacturing company that values both technology and people. I hope the company offers competitive salaries, health insurance, paid annual leave, and opportunities for professional training. These benefits would help me stay healthy, improve my skills, and maintain a good work-life balance. In addition, I would like the company to provide flexible working hours and a performance-based bonus system. Flexible hours would allow me to manage my time better, especially during busy personal periods, while bonuses would motivate me to work harder and achieve better results. Among all the benefits, I prefer professional training the most because it will help me continuously develop my expertise, keep up with new technologies, and advance my career in the long term.

One device that uses alternative energy to protect the environment is a solar-powered street light. It uses solar energy, which is clean, renewable, and available almost everywhere. I choose this type of energy because it produces no greenhouse gas emissions, reduces electricity costs, and requires little maintenance. The solar panel on top of the light collects sunlight during the day and converts it into electricity, which is stored in a battery. At night, the stored energy powers the LED lamp to provide lighting for streets and public areas. This system works automatically with light sensors, so it needs no manual operation. However, there are some problems, such as reduced efficiency on rainy or cloudy days and higher initial installation costs. Still, the long-term environmental and economic benefits make it a sustainable solution for communities.

In the future, I want to live in a smart house located near the beach, where I can enjoy fresh air and a peaceful view every day. My smart house will have technologies such as voice-controlled lighting, an automated temperature system, and security cameras connected to my smartphone. It will also include energy-saving devices like solar panels and smart appliances that reduce electricity consumption. The advantages of this house are convenience, safety, and lower energy costs. However, one disadvantage is that it may require high maintenance costs for advanced systems. I plan to live there with my family so we can enjoy comfort together. I want to live in this house because it combines modern technology, environmental friendliness, and a relaxing location, making it the perfect place for both work and leisure.
