Stone Assistance has been interested for several years in improving careers sawing techniques with cutting machinery chains.
Rigorous scientific approach to the problem has been developed to increase the profitability of this phase of sawing and make it more competitive.
Our approach is as follows:
Characterization of the mechanical properties of the stone
Study theoretical performance tools by laboratory tests
Choosing a suitable configuration
Performance monitoring on site using onboard instrumentation
Calculation of production costs
Laboratory tests are designed to assess the cutting performance configurations based on tests carried out on all media individually. These tests determine the distribution of forces on the configuration and locate the most stressed and least effective tools. This information helps to define the main causes of poorer functioning of certain configurations.
Tools of the same configuration tested individually.
Distribution of forces on a cutting configuration.
Comparing the response of three different configurations for cutting tests.
Laboratory cutting tests.
The performance of different configurations can be compared with each other to determine which ones will be most effective and thus guide operators to select the type of tools best suited to the application. Stone Assistance take those results in considereation to suggest design changes that will improve performance.
Stone Assistance also works on machines to instrument them and monitor their performance in order to validate the developed concepts. The instrumentation notably allows operators to be more sensitive to certain phenomena occurring during operations.
Stone Assistance has also developed a program that calculates the real cost of sawing with chains cutting machinery. The program allows to integrate the results of laboratory tests, technological parameters of machines and major costs to provide engineers with tools objective selection criteria.
