Assigned Department Objectives
Teaching Method
Outline:
General or Specialized : Specialized
Field of learning : Materials, Design and Production
Required, Elective, etc. : Must complete subjects
Foundational academic disciplines : Engineering,/Mechanical Engineering,/Design Engineering, Machine Functional Elements, Tribology
Relationship with Educational Objectives :
This class is equivalent to "(3) Acquire deep foundation knowledge of the major subject area ".
Relationship with JABEE programs :
The main goals of learning / education in this class are "(A), A-2", also "C-1" is involved. This is a course with university-equivalent content and is related to the Engineer Education Program.
Course outline :
In this lecture, drafting methods and standards for mechanical elements (gears, pulleys and sprockets, springs, welded joints, pipes, fittings and valves) are explained, followed by CAD drawing exercises. After that, the design calculation and the design procedure of hand-winding winches are explained, and actual design calculations and CAD drawings are made.
Style:
Course method :
After explaining each machine element mainly on the blackboard, the CAD drawing exercise is carried out. After that, regarding the design calculation of the manual winch, the calculation method and procedure will be explained centering on the blackboard, and each student will create the design calculation. Next, based on this design calculation, each student will practice creating a production drawing using CAD.
Grade evaluation method :
Design procedure, calculation method, accuracy and validity of calculation results and appearance in design documents(30%) + General rules and standards for five drafting exercises, accuracy, adequacy and appearance of the drafting method (50%) + Efficient and correct use of the basic functions of the CAD system for drafting(20%).
The distribution of grade evaluation is as described above, but if any of the above submissions have not been submitted, the evaluation score of this subject will be rejected.
Notice:
Precautions on the enrollment :
Students must take this class (no more than one-third of the required number of class hours missed) in order to complete the 3rd year course.
Course advice :
The only way to acquire the skills of reading and drawing of mechanical drawings is to make a steady effort on a daily basis. It is important to keep in mind the actual manufacturing process, and to work on the drawing while imagining the actual object.
Foundational subjects : Introduction to Science and Engineering (1st year), Machine Design and Drawing(2nd), Mechanical System Engineering Experiments and Practice Ⅰ(2nd)
Related subjects : Mechanical System Engineering Experiments and Practice Ⅱ(3rd year), Design and Machine Elements Ⅰ(3rd), Mechanical System Engineering Experiments(4th), Applied Machine Design(5th) etc.
Attendance advice :
You can learn mechanical drawing by drawing. Sufficient review centered on drawing exercises. In addition, note that if any of the submissions described in the grade evaluation method are not submitted, the grade grade will be rejected.
Late arrivals will be treated as late until half of each time has passed, but will be treated as absent after that.
