|Mechanical drawing is a fundamental subject, which connects mechanical design and manufacturing, in production technology educations. This course provides the basic of Graphic science, and two-dimensional mechanical drawings. Students learn how to make a mechanical drawing by CAD (Computer Aided Design) software through several projects. The students also study three-dimensional graphics design (3D-CAD) and manufacturing automation (CAM; Computer Aided Manufacturing). Tool path data for machining are created by utilizing CAM software, and mechanical structures are fabricated in practice with NC programs by using a vertical machining center. Through this course, students can learn the basics of mechanical engineering.
The goal of this lecture is to be able to:
1. Learn the basics of mechanical drawing standards including GD&T.
2. Based on mechanical drawing standard, a 3D image can be appropriately represented as 2D projections. Conversely, 3D images can be reconstructed from 2D projections.
3. Based on mechanical drawing standard, the projections of machine parts can be selected properly and dimensions, tolerances, and surface integrities are appropriately represented.
4. Three-dimensional shapes can be modeled using 3D CAD software.
5. Understand tool path generation using CAM software and learn the process of manufacturing machine parts by milling operation.
6. Draw simple mechanical parts based on design constraints.

Multiple assignments will be shown on the web and explained during class. Work on the assignment within and outside of class hours and submit it by the designated method within the deadlines. For basic assignments, feedback of evaluation results will be provided. It is necessary to re-submit the assignment with reference to the evaluation results and work to pass it within the deadline.

|Comprehension of the achievement level is totally evaluated based on grade of the submitted drawings and participations of the practical trainings.
The credit will be accepted if the basic problems can be handled properly among the primary practices that ask for an understanding of drafting standards. Also, participation in all hands-on training is mandatory. If the advanced problems can be handled appropriately, they will be reflected as a better grade accordingly.
|No registration requirements required.
The lecture style and evaluation method may be changed depending on the Covid-19 situation.
The lecture is held by face to face in lecture room or using e-larning. The e-larning method is written in NUCT, and bidirectional communication by Microsoft Teams.
The students ask lectureres by through NUCT "message" system.
The students share your opinions of this lecture by through NUCT "message" system.
|Responses to associated questions are given after lectures or during CAD practices.
