I want to tell about lathe machine because I like it very much. In my school workshop I see many machine, like drilling, milling, grinding, but I think lathe is most interesting. Lathe machine have heavy body, one spindle for rotate the work, one tool post for keep tool, and carriage for move tool. When I use lathe I can make round part, cut surface, make hole or thread. It is very useful for student in mechanical. I think use lathe machine have many step but I say simple step. First step is put the workpiece inside chuck and make it strong tight, because if not tight it can fly out and dangerous. Second step is put cutting tool in the tool post and set it same height with workpiece center. Third step is choose speed, feed, and then turn on the machine. The spindle start rotate and the workpiece move fast. Fourth step is move tool slow and make the cutting. We must careful because tool can break if go too fast. Last step is stop machine, measure the part, and clean chip. When I finish one work I feel very happy because the surface is smooth and round. Sometimes I make mistake, the size not correct, but I learn again and again. I like lathe machine because it not too hard but give many experience. For me, lathe is machine I like the most.

CNC router is one type of machine that I know and I like. This machine is use for cutting, carving, making shape from material like wood, plastic, sometimes metal also. It work by computer program, so user only need put design inside software and machine can follow that. The machine can move in many direction and do very detail, more good than when people cut by hand. I see many video on internet about CNC router and I feel it really modern. The feature of CNC router is have motor, spindle, table for material, and it connect with computer. With this it can make product look very nice, very exact. One big advantage is it save time and reduce mistake. Worker not need too much strong, just know how to use software. It also can run long hour without feel tired like human. Another good thing is CNC router can do many design same time, good for production and business. But CNC router also have problem. First, it is expensive, not easy for student or small shop to buy. Second, need knowledge about computer and machine, so not all people can use. Third, sometimes need maintenance, clean, and repair, if not it will not run good. In my opinion, CNC router is very useful for school, company, and workshop. It make product fast, exact, and look professional. Even it expensive, I still think it good machine, because in modern life, technology like CNC is important for future.

As a mechanical engineer, a commitment to protecting the planet Earth is essential, spanning both our professional duties and personal habits. First of all, in my daily life, I actively reduce consumption by saving water and electricity, making sure to turn off lights immediately upon leaving an area. First and foremost, my professional focus involves a fundamental shift toward sustainable design, prioritizing products that utilize alternative energy sources to cut carbon emissions drastically. Furthermore, I work to accelerate the adoption of cleaner technologies, such as designing high-efficiency systems for hydrogen combustion engines and electric vehicles. Besides, I am dedicated to integrating renewable energy solutions, including developing better harnessing mechanisms for solar and wind power in infrastructure projects. Last but not least, on a personal level, I support ecological health by consistently planting trees and diligently minimizing paper waste to ensure a holistic, daily commitment to preserving our planet's future.

Writing 2:

The Photovoltaic (PV) Solar Panel System is a machine central to the clean energy transition, running entirely on incident solar radiation. This vast and reliable alternative energy source is crucial because its operation generates electricity with zero carbon emissions, effectively combating climate change and air pollution. The system operates through the photovoltaic effect: semiconductor cells capture light photons, converting them into direct current (DC) electricity, which a necessary inverter then transforms into alternating current (AC) suitable for homes and the grid. Despite its benefits, using solar energy presents distinct problems. First of all, its intermittency means power generation ceases at night or during heavy cloud cover, necessitating expensive and large-scale battery storage solutions. Furthermore, the production of solar panels requires rare-earth minerals and involves energy-intensive manufacturing processes, raising concerns about material sourcing, end-of-life disposal, and recycling challenges.

One of the most useful devices that uses smart technology is the self-driving car. It is applied in the transportation field and is being developed by many automobile companies today. The car will be operated by using artificial intelligence, sensors, and GPS to detect the environment and make driving decisions automatically. People will only need to set the destination, and the car will drive itself safely and efficiently. This technology will bring many benefits, such as reducing traffic accidents, saving driving time, and helping elderly or disabled people travel easily. Moreover, it will help solve problems like traffic congestion and pollution by controlling driving speed and routes more intelligently. In the future, self-driving cars will make our journeys safer and more comfortable.

Writing 2:

In the future, I want to live in a smart house located near the beach, where I can enjoy the fresh air and beautiful scenery every day. My smart house will have many modern technologies such as an automatic lighting and air-conditioning system, voice-controlled home appliances, and a security system that uses facial recognition. The biggest advantage of this house is that it saves time and energy, making life more comfortable and convenient. However, its disadvantage is that maintenance costs and repair fees for smart devices may be high. I would like to live there with my family because it will provide a peaceful and safe environment. I want to live in this smart house because it represents a modern lifestyle and helps me balance work and relaxation perfectly.
