I’m a second-year student at Hanoi University of Industry and majoring in Robot and Artificial Intelligence. It is a full-time course which lasts four years. I have studied many subjects so far and I find Cutting Tools Design most difficult because this subject requires high accuracy and knowledge about the properties of materials. Besides, the subject making me feel excited, interested is English. I enjoy it most because it helps me a lot in future. At the university, I can improve five important learning skills: note-taking skills, organization skills, presentation skills, time management skills and teamwork skills. Next, I have some difficulties when studying at university. Firstly, my self-studying isn’t effective and my solution is trying to concentrate on studying more. Moreover, my tuition is rather high so I must find a part-time job to make ends meet and there are other difficulties. However, studying at university has benefits. I can meet and know many friends from different places. In addition, I’m taught about machines, practical knowledge. My lecturers and friends are very helpful and friendly. Therefore, I love studying at  HAUI so much.

The characteristic of ferrous metals is that they are durable and do not rust. Non-ferrous metals are soft, malleable and inflexible. Copper, bronze and aluminum are common metals in the group of non-ferrous metals. For ferrous metals we have cast iron and steel. Plastics are divided into two types including thermoplastics and thermosets. Thermoplastics get softer with heating and harder when cooled. Thermosets cannot be reformed by the application of heat.

Yesterday, I checked your product – the shaft and found some design mistakes. In the design drawing of the shaft, it is 50 millimeters plus or minus 0.25 millimeter and the length of the actual shaft is 50.05millimeters. It is inside tolerance. Next, the diameter of the shaft in the drawing is 6.010 mm plus or minus 0.004 mm, so the minimum diameter of the actual shaft is 6.006 mm. But its actual diameter is 6.000mm and it is out of tolerance. Finally, the hole depth of the shaft varies between 9.75 mm and 10.25 mm. And the actual hole depth is 10.30 mm. what a pity! Your product is rejected. I hope you can produce better products.
