The effects of different hand tool blade coatings on force demands when cutting wood

The usability and ergonomics of axes

“…This part of the study has been reported earlier and thus will not be discussed further in this paper (Pä ivinen and Heinimaa, 2003). This study consisted of the following methods: In durability tests a combination of standard procedures (ASME B107.55M-1998;BS 2945BS :1995 was used.…”

Measuring Coupling Forces Woodcutters Exert on Saws in Real Working Conditions

“…Its mechanical and shear properties depend on the force applied and the cutting direction with reference to the direction of wood fibres [14]. That is why coupling forces were mea sured during felling, cross-cutting and limbing.…”

The Effects of Blade Coatings on Corce Demand When Pruning Grape

“…Therefore, the friction coefficients of the materials to be used are important. For example, Paivinen and Heinimaa (2003), reported that the friction coefficients of steel and teflon versus dry wood are 0.5 and 0.1, respectively. For these reasons, it is important to consider applications that reduce the coefficient of friction between the pruning blades and the material to be cut.…”

“…By implementing ergonomics and usability issues in product design, the user's well-being can be improved by decreasing e.g., the risk of musculoskeletal disorders (Paivinen and Heinimaa, 2003). Thus, reducing the shear force required by hand pruning shears; it will help to reduce the inconveniences that may arise while increasing job success and working comfort.…”
