Product design and manufacturing methodsLaajuus (15 ECTS)

Objective

On completion of the course, the student will be able to design and manufacture a product, choosing the right materials for it. The student will be able to read and draw technical drawings. The student will be able to make workshop drawings, and choose the suitable tolerances and surface roughness according to the use and production methods.
The student will be familiar with the principles of various manufacturing processes. The student will be able choose the most suitable and cost-effective manufacturing process for each product and understand the impact of the choice for the sizing, measuring accuracy and design of the product.
The student will be familiar with the most common materials, as well as with the effects of heat treatment, alloying and coating on these properties.

Content
