Entry requirements

40 credits within the Bachelor's Programme in Mechanical Engineering.

Learning outcomes

On completion of the course, the student should be able to:

• explain basic technological concepts for the methods: plastic machining, metal cutting, welding, powder metallurgy fabrication, form-manufacturing (casting, forging, injection moulding, etc.),
• describe the relationship between different manufacturing processes and the product characteristics (eg, tolerances, surface smoothness, manufacturing cost),
• prepare simpler components for fabrication with CNC machine tools, including tool selection, calculating cutting data, and the development of control software,
• prepare simple products for joining by welding, which takes into account the geometry, weld gaps, joint preparation and positioning as well as the formation of thermal stresses.
• use basic engineering technical measurement techniques to verify product functionality and quality,
• independently utilize knowledge about manufacturing methods for defining the product geometry.

Content

Plastic processing: Analysis of energy, power and force requirements for e.g. forging, pressing, bending, and thread and plate production.

Cutting processing: Analysis of cutting procedures, tool wear and lifetime, with an emphasis on lathing, cutting (3-axial and 5-axial), drilling and grinding.

Welding: Manual arc and gas welding (MMA, MIG/MAG, TIG). Design of welded joints.

Mechanical engineering measurement techniques: Measurement gear, gauges, jigs, measurement devices and modern measurement machines.

Casting: Centrifugal casting, wax melting, sand casting.

Powder metallurgy: Powder production, powder pressing, sintering and finishing.

Manufacturing of plastic elements: Injection moulding, compression moulding and extrusion.

Other manufacturing methods: Water cutting, laser cutting, sparking, etching and extrusion.

Rapid prototyping: Methods for manufacturing of 3D machine elements of polymers and metals.

Instruction

Lectures, assignments, laboratory, and field study/visit at a fabrication facility.

Assessment

Written exam (6 credits). Project (3 credits). Laboratory (1 credit).

If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
