29719 - Mechanical Manufacturing Processes

Course Unit Page

Academic Year 2022/2023

Learning outcomes

The student will learn the basic principles of manufacturing processes based on cutting by means of machine tools. He will be able also to organize simple production sequences (including tooling geometry, machine tool selection) basing on product geometry, batch number and dimensional requirements.

Course contents
