Learning outcomes
|
The course introduces students to the principles of machining technology and theoretical aspects of machining, so that on the basis of this knowledge was a graduate is able to apply them in solving specific problems in machining technology. Understanding and knowledge of the theoretical aspects of machining technology and is an important prerequisite for the successful application of this technology and its mastery in industrial applications.
