Entry requirements

40 credits within the bachelor program in Mechanical Engineering.

Learning outcomes

After a successfully completed 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.
