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 the cutting conditions
Students will learn the theory of chips and creating a new surface, Students are able to oriented in various machining methods, their requirements and applications Students can create the technological process of the alternatives, The student knows the determination of cutting process parameters, student is well versed in the areas of installation and can determine tolerance for assembly
