Mechanical Engineering Drawing Training Program
General Introduction
The Mechanical Engineering Drawing Course is an in-depth training program designed for students, technicians, and personnel in the mechanical industry. The program is structured to equip participants with the comprehensive knowledge and skills necessary to read, understand, and accurately represent mechanical technical drawings — one of the fundamental pillars in design, manufacturing, and product inspection.
Course Objectives
- Equip knowledge and skills in reading, understanding, and representing mechanical technical drawings.
- Familiarize participants with drawing presentation standards, projection methods, symbols, tolerances, and fits.
- Proficiently execute detail drawings and assembly drawings both manually and with software assistance.
- Build a solid foundation for mechanical engineering students working in design, production, and technical inspection.
Training Duration
Theory: 45 periods
Instructor in Charge
Assoc. Prof. Dr. Nguyen Thanh Hai
Department of Equipment & Mechanical Materials Technology – Ho Chi Minh City University of Technology (HCMUT), VNU-HCM.
With years of teaching and practical experience, the instructor will accompany trainees throughout the course.
