Single-Course English 5 ECTS

Precision Machining

Overall Course Objectives

The objective of the course is to enable the students to use the capabilities of precision machining processes to produce complex components with high accuracy and very fine functional surfaces. The students will learn about state of the art solutions for precision machining including cutting tool materials and tool wear, precision machine tools, thermal and mechanical errors, machining strategies, advanced analytical modelling tools, error suppression and error compensation strategies, fine abrasive processes. During the course the students will be introduced to the use of computer aided manufacturing (CAM) as a software tool to execute machining operations. The course focuses on precision machining of metals and alloys.
