Learning outcomes of the course unit
Students will acquire knowledge of qualified technological process selection, including foundry technology. They will be able to select proper clamping of workpieces, production (cutting) conditions, cutting tools and materials, do workpiece checks, calculate production times and production costs.
Prerequisites
Knowledge obtained in the course of previous study, namely in the fields of theory and technology of machining, material science, metrology, mathematics, physics, structures and properties of cast materials.
Planned learning activities and teaching methods
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
