This industrial short course on Metal-Cutting Finishing Methods gives the participant an applied knowledge about the various finishing operations used as the final step in the manufacture of precision components. It is founded on an in-depth understanding of the important role that surface integrity plays in the performance of components. The course explains the theory and application of hard machining, grinding (including dressing) and abrasive fine finishing (e.g., honing, superfinishing).

Content

Module 1: Surface integrity

  • Classification / definition
  • Surface (texture) finish
  • Residual stresses
  • Sub-surface features
  • Metallurgical aspects

Module 2: Hard machining

  • Operations and capability profiles
  • Process fundamentals – chip
    formation, cutting forces, specific energy, thermal aspects
  • Machine and tooling  requirements

Module 3: Grinding technology

  • Grinding fundamentals –
    mechanisms, grindability, parameters, thermal aspects, cooling
  • Dressing fundamentals
  • Grinding wheels & dressing tools

Module 4: Abrasive fine finishing

  • Classification; finishing methods vs. functional performance
  • Honing, superfinishing, lapping /
    polishing, vibratory finishing
  • Guidelines for process design

Information

The course contains four modules which are organized into two-week periods. Each module begins with a full day of lectures and then continues in a remote learning segment, during which the participants are divided into small groups to work on case-studies, assignments and accompanied learning tasks. Course instructors facilitate the group activities in an online learning management system. The modules end with half-day reflection, feedback and a debriefing lecture.

The course is organized in a fully online format.
Course completion is based on a series of practical online assignments. In order to be issued with university credits you will need to meet the requirements outlined in the course handbook made available to you as soon as you start the course.

For more information about the course get in touch with Peter Krajnik (examiner) or Gustav Holmqvist (Course manager).

Course language

The course is offered in English.
