Learning outcomes
|
The course introduces the theoretical aspects of machining, then the individual machining technologies, production processes, technology of machined parts. The aim of the course is to know the nature of the machining process and orientation in the dependencies of the process, the ability to objectively choose a particular technology, determining cutting conditions.
The student acquires knowledge of the essence of the machining process and is familiar with the dependencies of the process, is able to objectively choose a particular technology, determine the cutting conditions, knowledge of the assembly of technological and assembly procedures.
