Contents

A large part of the course is carried out with computer tools, such as MathCad, for the simulation of the metal cutting process.

The compulsory written assignments contain experimental elements.

The course includes the following: The Production Reliability concept and the application on metal cutting. Basic metal cutting considerations. Tool deterioration and consequences. Modelling of mechanical loads, cutting resistance, load relation functions, load variation functions etc. Comparison of material properties. Thermal analysis and modelling of the cutting process. Stress calculations and stress analysis on cutting edges. Work material structures and machinability. Tool deterioration, tool wear and wear models, cracking, fracture, plastic deformation and chemical degradation. Testing of cutting tools and tool properties, tool characteristics. Multi-tooth cutting processes, load interference and load interaction. Measurement of cutting forces and development of cutting force sensors. Process dynamics, segmentation etc. Vibrations and instability, process damping and the relation to tool geometry. Micro geometries and dynamics. Active tool damping and control.

Examination details
