Course Objective

The main objective of this course is to teach the students efficient use of technology under the light of some developed natural stone cutting theories as well as equipment selection in natural stone processing plants, cost analysis and monitoring of product quality. Thus, the present will contribute to the energy and material consumption sustainability in natural stone production.

Learning Outcomes of the Course Unit

1   Adoption of cutting (sawing) theories in natural stone processing.
2   Understanding the details of wear mechanisms prevailing in gangsaw blades and circular saws.
3   Assessment of operating parameters and their influence on cutting technologies.
4   Assesment of efficient use of resources in natural stone production.
5   Optimization of energy consumption in natural stone processing.
