Subject: Hi!?

Hi abc,

How are you doing? I hope you’re going well.

I’m a second -year student at Hanoi University of Industry now, majoring in Robot and Artificial Intelligence. In  university, I learned many different skills such as organizational skills, teamwork skills, time management skills,... in addition to very important communication skills. And after 4 years of studying at school, I will graduate with a bachelor's degree, acquire knowledge and soft skills to serve my future work. but have difficulty finding and reading study materials because they are all in English. The only thing to overcome that difficulty is to improve your English level. But I like university because there I experience many things.

Love much,

Tda

Dear HJB Company,

I hope this email finds you well. We are interested in purchasing two CNC milling machines for our manufacturing operations. We have seen the product listed on your website under the reference number 200 MC 6453, with serial number 67398, priced at $50,489 each.

These machines will primarily be used to cut flat metal surfaces and improve the speed of our manufacturing processes. We would appreciate it if you could arrange delivery by November 8 to our facility located at Ha Noi city

Regarding payment, we prefer to settle the invoice in cash upon delivery.

Looking forward to your prompt response and the smooth processing of our order.

Best regards,

tda

Upon comparing the technical drawing of the lathe shaft with the actual measurements taken from the product, slight discrepancies were observed. The design specified a length of 50.25 mm, while the measured length was 50.4 mm. Similarly, the design diameter of 6.004 mm slightly exceeded the actual diameter of 6.015 mm. The blueprint indicates a hole depth of 10.25 mm. Actual Hole Depth: Upon inspection, the hole depth is measured to be 10.12 mm.. Despite these minor variations falling within acceptable tolerance limits, it is recommended to maintain closer adherence to specifications for future productions. Consequently, the shaft is accepted for use, albeit with a cautionary note to ensure tighter control over manufacturing processes to uphold quality standards.

In mechanical engineering, materials are broadly classified into four main categories: metals, polymers, ceramics, and composite materials. Metals are highly versatile and can be further categorized into ferrous metals (e.g., iron, steel, and stainless steel) and non-ferrous metals (e.g., aluminum, copper, and titanium). Polymers consist of long molecular chains and are categorized as thermoplastics (e.g., polyethylene, PVC) and thermosetting plastics (e.g., epoxy resin). Ceramics encompass a wide range of inorganic compounds such as silicon carbide and alumina, known for their high-temperature resistance and hardness. Composite materials combine two or more distinct materials to enhance specific properties, with examples including fiberglass, carbon fiber reinforced polymers, and concrete. Each material category offers unique properties suited for various engineering applications.

Last summer, while working in a manufacturing plant, I encountered a frustrating problem with one of the assembly line robots. During a routine production run, the robot's arm suddenly malfunctioned, causing a significant delay in the process. The issue stemmed from a faulty sensor, which disrupted the robot's ability to accurately gauge its position. After assessing the situation, I promptly shut down the system and conducted a thorough inspection. Upon identifying the defective sensor, I replaced it with a new one and recalibrated the robot. Despite the initial setback, resolving the issue efficiently left me with a sense of accomplishment and reinforced my problem-solving skills in a high-pressure environment.
