Start-up of a Kistler 9129AA dynamometer on a custom rotation machine and investigation of its potential eligibility for cutting force measurement in wood

Abstract: In the manufacturing industry, the mechanics of metal-cutting is well-understood and used to improve cutting processes. The mechanics of wood-cutting are still in its early stages and further research is required. Although there is a lack of knowledge regarding cutting mechanics for wood, today's cutting speeds in modern sawmills are as high as 100 m/s and the production rate and quality are high, to the cost of unnecessary wood-based waste. To be able to reduce waste it is necessary to understand the process of wood machining in detail. A Kistler 9129AA dynamometer was commissioned in a custom rotation machine and compared to an already existing sensor. It was shown that there were significant deviations between the measurement results of the evaluated sensor system and the Kistler 9129AA dynamometer. In this specific setup, the Kistler dynamometer was not able to deliver the same results as the existing sensor system. Therefore, the eligibility of the Kistler 9129AA dynamometer to measure cutting forces in wood could not be concluded.
