Course Objectives
(1) Learn about the design process up to machining through the planning, designing, and drawing of a two-stage three-axis gear decelerator, a typical turning machine consisting of various mechanical components such as gears, bearings, and axles. Can creatively plan the structure, shape, and dimensions that satisfy the performance and complete a gear decelerator drawing based on the design calculation of a gear decelerator they created in Design and Drawing IV A, to acquire comprehensive machine design skills.
(2) Create a plan drawing, part drawing, and assembly drawing with AutoCAD Mechanical.
(3) Learn to employ many different design and drawing methods for mechanical elements, and through repetition by reviewing the material, to independently drive design promotion and to learn how to use design reference materials and reference examples of machine design. Learn a wide range of design ideas including the importance of delivery time, to learn the necessity of and methods for continuous learning.

Assigned Department Objectives
Teaching Method
Outline:
Learn about the design process up to machining through the planning, designing, and drawing of a two-stage three-axis gear decelerator, a typical turning machine consisting of various mechanical components such as gears, bearings, and axles. In the first semester, students will learn how a mechanical design should be through lectures on technical calculations necessary for design. They will plan gear decelerators and prepare design calculations, and recognize the importance of design calculations. In the second semester, students will creatively plan structures, shapes, and dimensions in a manner that was given to them to satisfy the performance given, then design using AutoCAD Mechanical, to acquire comprehensive machine design skills.
This course will be held in a lecture and lab style and taught by an instructor who is in charge of machine design in a company using his experience. Based on the design calculations for a helical gear decelerator completed in Design and Drawing IV A, it will teach how to use AutoCAD Mechanical, and how to create a planning drawing and assembly drawing of a helical gear reducer, and a part drawing of axes and helical gears.
Style:
Students will create drawings for major parts based on the design calculation of a helical gear decelerator they designed in Design and Drawing IV A, using CAD. Classes will be conducted in a lab style.
Notice:
This course's content will amount to 90 hours of study in total. These hours include the learning time guaranteed in classes and the standard self-study time required for preparation / review, and completing assignment reports.
(1) Understand why design calculations are necessary, and learn how to write design calculations that others can understand. (2) Learn the importance of creativity by incorporating ideas and repeating trial-and-errors to realize specifications to satisfy the original purposes. (3)Recognize the importance of delivery time.
Students who miss 1/3 or more of classes will not be eligible for evaluation.
