|
Name of subject: Machining Technology |
Instructors:
Prof. Filip Miletić, Prof. Dejan Ivezić |
|
Status: Compulsory |
|
ECTS: 5 |
|
Prerequisites: - |
Course Objectives:
Students are introduced to the basic principles of production technologies used in metal processing. The accent is on cutting process and process by plastic deformation. Through the development of individual numerical and graphic calculations, the students acquire theoretical knowledge applied to the design of concrete technological processes (processing by cutting, plastic deformation). |
Learning Outcomes:
Examining the processing system, which represents the central carrier of the technology in the field of metalworking, the elements of this system and the basic division of processing methods. Understanding the technical characteristics and indicators of the quality of the processing systems, through functional and disorder systems. Adoption of cutting systems (basis of cutting theory, machines, tools, accessories, calculation of regime process) and deformation theory with basic methods of processing and review of machines and tools for processing by plastic deformation. |

Conduct of the Course:
Content of theoretical teaching is expose by the method "ex cathedra" with the support of computer presentations, the second part of the lecture is done by the "case study" method, that is, the analysis of characteristic cases and examples that illustrate theoretical content. Seminar work is obligatory for all students, as well as independent numerical and graphic paperwork which includes the prescription of the technological process on lathe and forging process. A visit to the production facilities of the metal-working industry. |
