97464 - Laboratory of Mechanics P-1-BO

Learning outcomes

At the end of the workshop, the student knows the basics for the interpretation and execution of technical drawings with conventional methods of representation (according to UNI ISO standards) and CAD. In particular, the student: - knows the main tools of three-dimensional solid modeling for the creation of mechanical components; - is able to realize drawings of parts and assemblies and dimension them; - can define kinematic and dynamic simulations of constrained components, and be able can interpret the results.

Readings/Bibliography

Summary handouts are provided for the course and study. For additional information, you can consult any Industrial Technical Design textbook for secondary schools.

Teaching methods

In-person lessons will be held in the lab.

Each student will have access to a PC with the necessary software pre-installed.

Instructions will be provided for installing the same software (with a student license) on their personal PC, allowing them to use it from home.

Assessment methods

The exam will assess technical drawing skills, particularly reading, comprehension, and unified representation methodologies. Knowledge and use of dimensional and geometric tolerances will also be assessed. Students must demonstrate the ability to replicate the use of CAD as discussed in class, demonstrate independent modeling of three-dimensional objects, and understand drawings. Students must be able to assemble components to generate mechanical motion. Students must be able to configure a mechanism for these motions within PTC/Creo to perform kinematic and/or kinetostatic simulations.

Teaching tools

Documentation of the slides used in class will be shared, along with copies of the theoretical material needed to understand technical drawing. Copies of the unified tables required for the exam will also be provided.

Instructions for installing CAD software on personal devices with a student license will be provided.
