Đề thi cuối học kì 1 môn Công nghệ kim loại năm 2025-2026

This document serves as a comprehensive final examination for the "Công nghệ Kim loại" (Metal Technology) course, crucial for evaluating students' foundational understanding and practical application skills in manufacturing engineering. It underscores the importance of a holistic grasp of metal processing, including casting, metal forming, and welding, which are cornerstone disciplines in mechanical and materials engineering. The assessment aims to ascertain students' proficiency in identifying process parameters, analyzing defects, and applying design principles essential for industrial production. This structured evaluation ensures that future engineers are well-equipped with the theoretical knowledge and problem-solving capabilities required for real-world manufacturing challenges.

University students in Mechanical Engineering, Manufacturing Engineering, and Materials Science, particularly those studying metal technology. Also relevant for educators and curriculum developers in these fields.

The examination meticulously covers a broad spectrum of topics within **Công nghệ Kim loại**, divided into multiple-choice and free-response sections. The 40 multiple-choice questions delve into critical areas such as solidification processes, **khuyết tật đúc**, mold design elements like **mặt phân khuôn**, **đậu ngót**, **hệ thống rót**, and machining allowances. Furthermore, it explores various **gia công áp lực** techniques, including **rèn** (open die and die forging), rolling, and hot working, along with their associated design considerations and microstructural impacts. The welding section comprehensively assesses knowledge of different **hàn** processes, weldability, heat-affected zones, and common defects like lack of fusion. A practical free-response question challenges students to apply design principles by creating a pattern drawing, simulating a real-world task in manufacturing. This assessment strategy not only evaluates theoretical comprehension but also tests the ability to integrate knowledge from diverse sub-disciplines. By requiring students to interpret technical drawings and propose manufacturing solutions, the exam effectively gauges their preparedness for addressing complex engineering problems, highlighting the practical value and implications of a robust education in **kỹ thuật sản xuất** and **kỹ thuật vật liệu**.
