| MAKL7523 | Mechanics of Forging | 3+0+0 | ECTS:7.5 | | Year / Semester | Fall Semester | | Level of Course | Third Cycle | | Status | Elective | | Department | DEPARTMENT of MECHANICAL ENGINEERING | | Prerequisites and co-requisites | None | | Mode of Delivery | Face to face, Practical | | Contact Hours | 14 weeks - 3 hours of lectures per week | | Lecturer | Prof. Dr. Ömer Necati CORA | | Co-Lecturer | | | Language of instruction | | | Professional practise ( internship ) | None | | | | The aim of the course: | | This graduate course aimed for providing fundamental information on forging which is one of the oldest metal forming processes. In addition, types of forming processes, calculation of loads and stresses in forging via analytical, emprical and numerical techniques, factor affecting forging (load, lubrication, coefficient of friction), analysis of forging defects, review on some of the forging products ( knifes, tools, bolts, rolling bearings,etc.) will also be covered. |
| Programme Outcomes | CTPO | TOA | | Upon successful completion of the course, the students will be able to : | | | | PO - 1 : | distinguish various forging processes and determine the appropriate forging method for a part in a specific form. | | 1,3,6, | | PO - 2 : | calculate the necessary forging load and contact pressure for some simple shape parts in open-die forging. | | 1,3,6, | | PO - 3 : | analyze the presses used in forging operations and their features. | | 1,3,6, | | PO - 4 : | analyze the important points in die design and press selection for a part to be forged. | | 1,3,6, | | CTPO : Contribution to programme outcomes, TOA :Type of assessment (1: written exam, 2: Oral exam, 3: Homework assignment, 4: Laboratory exercise/exam, 5: Seminar / presentation, 6: Term paper), PO : Learning Outcome | | |
| Bulk metal forming processes, Materials Characterization, Hot and Cold Forging, Analytical and Empirical Analysis in Forming, Forming Defects, Metal Flow and Pre-form Design, Numerical Modeling of Forging, Die and Mold Design, Process analyses for forged products: Knifes, tools, bolts, bearings etc. |
