After having completed this course, the student should:
- be able to recognize and compare different production methods in sheet metal fabricating industry
- be able to understand how the price of the sheet metal component forms
- be able to apply the knowledge of modern sheet metal manufacturing in practice
- be able to manufacture sheet metal components and assemblies in own factory
- be able to purchase sheet metal components and assemblies from subcontractors
- be able to understand the simulation, automation and robotics importance of the efficient
manufacture of sheet metal components and assemblies
- know how to design sheet metal products with 3D software and simulate the manufacturability of
different sheet metal components
- be able to recognize the connection of 3D design to used materials, manufacturing methods
and machine systems and their goal of sustainable and productive manufacturing


The course focuses on manufacturing and manufacturability of sheet metal products in such a
way that the students will reach a comprehensive understanding of the manufacturing cost
factors in sheet metal products manufacturing. Material quality, different coatings,
subassembly's accuracy, process properties and as well as qualitative preparations of multi-
technical products are affecting to sheet metal subassembly and finalassembly. These
aspects are explored in this course. In addition, the focus of this course is on sheet metal
production: in automation practices and safety issues. The course covers traditional and
automated sheet metal manufacturing processes trends and visions. Numerous case examples
used in this course are straight from the real world, examples are analyzed and solutions are
searched in teams. The course is related to sustainable development.

Lecture topics:
- Raw materials, sheet and platemetal materials
- Cutting of materials, principle of cutting and machine tools for cutting
- Punching of materials, principle of punching and punch presses
- Special tools for punching and bending, new trends in tool sector
- DFMA aspects in sheet metal products
- Presses
- Bending of materials, principle of bending and bending devices
- Fine blanking
- Press tooling
- Storing materials, sheet and platematerials, semi-finished products and assembly parts
- Sheet metal production, LEAN aspects, quality and productivity
- Mechanical joining methods

Factory visit:
- Factory visit to sheet metal parts fabricating company

Laboratory exercises:
- 3D-planning of sheet metal parts
- Punch press environment, programming and use
- Press brake environment, programming and use
- Cutting of materials using shear

- Mechanical joining methods
- Production planning and production capacity calculations

Teaching Methods 

Lectures and factory visit 30 h, laboratory exercises and individual guidance 14 h, including practical tasks of manufacturing sheet metal components. Practical tasks includes designing of 3D sheet metal parts using 3D CAD-program, programming NC-machines using CAM-system and interactive operator interface, manufacturing of needed sheet metal parts (both 2D and 3D -parts) and sheet metal component assembly using different joining methods, seminar work 36 h, independent work 50 h. Total workload 130 h.
The course is suitable for distance learning.

Students at LUT will participate each laboratory exercise. For distance learning students there will be one demonstration day covering all exercise topics, the date will be informed early autumn.
