Machining Technology (FSI-DTB-A)

Academic year 2018/2019
Supervisor: prof. Ing. Miroslav Píška, CSc.  
Supervising institute: ÚST all courses guaranted by this institute
Teaching language: English
Aims of the course unit:
The aim of the course is for students to master fundamental machining technologies based on the principles of physical and chemical interactions of the machine-workpiece-tool system. In addition, manufacturing assembly and other concerned disciplines are dealt with.
Learning outcomes and competences:
Students will be familiar with physics and other aspects of machining. They will be able to define technological processes for all fundamental manufacturing methods and will have an overview of principles applied for technological assembly.
Prerequisites:
Successful completion of the subject ”Production Technologies II”, knowledge of fundamental methods of machining. Knowledge of mathematics, physics and material science.
Course contents:
The course deals with the following topics: Fundamentals of machining. Dimensioning and tolerances. Physics of machining. Cutting forces, heat and temperature of cutting. Cutting materials and their use. Productivity and economy of machining. Wear of cutting tools. Main groups of machines and technologies. Technology of turning, drilling and milling. Shaping, grinding, honing and reaming. Non-conventional methods of machining (EDM, laser, plasma assisted machining, ultrasonic, water jet). Gear production. CNC machining. Rapid prototyping, 3D print. Tolerance and dimension chains. Selective assembly.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes:
Examination consists of a written and an oral part. The written part is focused on the solution of a technological problem. The assessment reflects student’s professional skills. The oral part tests student's knowledge of a topic selected randomly from the concerned areas to assess the depth of understanding.
Controlled participation in lessons:
According to the studied topic some lessons will be practicals - carried out in the lab, and some will be focused on the theory - calculations carried out in the classroom in a seminar form. Absence from seminars should be substituted for by attending a seminar with another study group or individually by the agreement with the teacher. Lessons may be occasionally inspected by the head of the department.
