COURSE AIM AND OBJECTIVES

The objective of this course is for students to obtain knowledge on digital technologies in manufacturing and production systems and skills of Siemens NX software 3D modeling and computer aided manufactory (CAM) technology.

REQUIREMENTS

During this course the level of knowledge and skills obtained by the students will be assessed by 3D parts models, computer aided manufactory (CAM) technology of 3D parts models and exam. 3D parts models and CAM technology are based on Siemens NX software.

The grade for 3D parts models is 30% of the final grade. The grade for CAM technology of 3D parts models is 50% of the final grade. These grades will be based on class activities. The remaining 20% of the grade will be based on exam.

Most of the readings and educational materials for the course are internet sites, open web-sources and video lectures. The additional reading is strongly recommended for extending students’ knowledge and further research in the field.
