Sawing technologies

Sawing technologies – found in almost every production chain – also play a major role when it comes to processing a wide range of materials. That is why the Department of Lightweight Construction Technologies at Fraunhofer IPA has set itself the target of implementing innovative technologies to further reduce cutting forces and noise levels. These technologies also enable thinner tools to be used and circular saws to be manufactured more cost-effectively.

Close networking of competencies and mutual collaboration with the Institute for Machine Tools at the University of Stuttgart (IfW) in the field of sawing technologies has led to foundation of the “Stuttgarter Kompetenzzentrum Sägen” (SKS). This partnership enables us to find solutions to industrial and research tasks quickly and efficiently. We address challenges concerned with sawing processes in the areas of machining, cutting, machine tooling and machine technologies.

With our in-depth knowledge – from the saw tooth through extraction systems right up to safety– we offer our customers unparalleled process expertise. By taking a holistic approach and optimizing the overall situation, we not only improve aspects of a process but also consider their effects on other systems. Additionally, this serves to increase the global cost effectiveness of the separation process.

 

Machining and cutting processes

Circular saws are highly efficient cutting machines. Besides designing machinery and optimizing tooth geometries, our research also focuses on wear and quality. Our expertise lies in analyzing, developing and optimizing the complete process chain.

 

Parent wheel design and optimization

A particular skill of Fraunhofer IPA is designing and optimizing parent wheels on the basis of finite element analyses. These enable us to ascertain the effects of temperature gradients, rotation and tensioning processes.

 

Ultrasound sawing

Sawing processes are highly effective. However, when used in industry, there is a constant demand for even better performance –thinner blades, higher speeds, lower cutting forces, etc. We offer a possible solution approach using ultrasonic-assisted sawing.
