The main objective of this course is to achieve basic competence in the process of generating of technical systems and innovation, as well as introduction of basic academic knowledge of the capabilities and use of specialized software applied in three stages in the product development (design, elaboration of technological processes and the production).

Students will acquire knowledge, tools and practical skills in the application of specialized software for the design and construction (engineering design) as well as programs that enable communication between various software for different purposes.

Basic definitions provided in mechanical engineering design. The notion of a technical system. The concept of technical innovation. Creation of technical systems and innovation. Basic capabilities of CATIA software (3D models and from them derived two-dimensional drawings and plans, linking them with additional modules for the kinematic calculations, FEM calculations and NC-programming). Processing of 3D geometry imported into CATIA software from 3D scanners; translating from .stl format to .igs or .stp records suitable for improving the geometry and FEM analysis. Basic design methods in the program SolidWorks. Interface programs that enable communication between the software for different purposes, and their interconnection. Linking programs CATIA and SolidWorks programs for the implementation of the finite element method Ansys and Abaqus; process optimization design. Methods of computer analysis and optimization of the product; parametric optimization of three-dimensional structural elements (Goal Driven Optimization in Ansys) and structural optimization (using Altair HyperShape). DELMIA software package; virtual planning, defining, monitoring and controlling production processes necessary to transform a computer model to a real mechanical products.

Examples of the application of software tools in the processes of the designing products used in the motor vehicle industry, shipbuilding, mechanical engineering, machinery, aviation,... Practical exercise on a 3D printer. Demonstration exercise of the NC machine.
