Workpieces from ferro-magnetic materials influenced by machining can build a magnetic field, which can cause problems in production or application. One of the assumed causes of magnetism occurring in cutting processes is the change in materials structure due to the impact of the tool. To study those influences by the process, milling tests are carried out. The magnetic field is measured by means of sensors functioning on the basis of the Hall effect. The coherences between geometry, kinematics, technological parameters, time dependency and the magnetisation characteristics of the workpiece are regarded.
