Outline |
|
In order to design a machine, it is necessary to select the material of parts constituting it, strength evaluation, and study of manufacturing / assembly method. Also, it is necessary to properly select machine elements such as screws so as to meet required specifications. The design information obtained in this way is transmitted to the manufacturing site using means called "drawings". This work is "drawing". In order to correctly communicate information, various rules for drawing are defined. In this course, students will understand these rules and actually create drawings using drafting tools.
The aims in this lecture are to obtain knowledge on DP1 and to train goal achievement on DP3.

Objectives |
|
Students will learn the machine drawing rules and understand the basics of machine drawing through assignment practice. Specifically, targets are the following items:
(1) Understanding the projection method and converting a three-dimensional object to a two-dimensional plane
(2) Understanding and using basic drawing rules such as dimensioning and tolerance
(3) Understanding the workings of machine elements such as screws and gears and expressing them in drawings

Grading Policy |
|
Evaluation is based on the submission of assignments to be presented in each lecture.
Evaluate grades according to each submitted subject.
Since the assignment will be returned after checking, please use it to confirm the degree of comprehension and target achievement.

Textbook and Reference |
|
Text is "Foundation of Mechanical Design and Drawing 2nd Edition", T. Tsukada, Mathematical Engineering Company, ISBN 978-4901683685 or "JIS standard drafting method 14th full revised edition", O. Kiyoshi, science and engineering school, ISBN 978-4274221187.
Both texts match the lecture. Please be sure to carry one and always refer to it. It is necessary even when drawing or reading.
|
| ５． |
Requirements (Assignments) |
|
It is desirable to practice so that you can master basic drafting tools (triangle ruler, compass etc.). Exercise assignment will be issued every lecture. It is a level that can be completed within the lecture time. But if students do not make it in time, submitting it the next lecture will be allowed. So please complete it.
In addition, contents of each lecture can be understood by textbooks and on LMS. Please read it before the lecture. (Half an hour)

Note |
|
The task is basically drawing creation. Be sure to bring A4 size grid paper and drawing tools such as, triangle ruler, compass etc. Also do not forget to bring your textbooks as described in section 4.
