“…Within a particular tree species, there are different factors affecting chip length, such as wood feed angle (ε), cutting edge angle (β), knife back angle (α), and cutting blade speed or chipper knife speed (the most important parameter), which can be adjusted so that there is an optimal relationship between the length and thickness of the chips. Such uniformity of the chip thickness depends to a large extent on the precise setting (extension) of the chipper knives around the circumference of the chipper disc (Reczulski 2015).…”

The paper is focused on the research of chipper knives with a straight and modified cutting edge in order to determine the energy consumption of the chipping process and the uniformity of the size of the fractions of the designed chipper knife for the production of dimensionally uniform chips. The research took place on two different tree species where the representative of the coniferous tree was the common spruce (Picea abies) and the deciduous tree was the winter oak (Quercus petraea). The research took place on a PTO-powered (power take off) disc chipping machine where it was not modified for research purposes. The results showed that a knife with a modified cutting edge is higher in terms of energy consumption than chipper knives with a straight cutting edge. From the evaluation of the sieve analysis for a chipper knife with a modified cutting edge, the energy chip of uniform granulometric composition is a homogeneous bulk material.

“…However, the design of modern tools and machines for wood processing should be aimed at reducing the energy consumption of the process (Spinelli et al 2015;Orłowski et al 2020;Warguła and Kukla 2020) as well as the impact on the environment (Manzone 2015;Prada et al 2015;Spinelli et al 2018) and machine operators (Magagnotti et al 2014;Gulci et al 2018;Licow et al 2020). These requirements can be achieved when designing machines by changing the construction of cutting mechanisms (Spinelli et al 2015;Reczulski 2018;Flizikowski et al 2021) or by changing the method and type of fuel used to power the drive units of the machines (Prinz et al 2018;Warguła et al 2020a, b), for example. Amateur manual tools or industrial wood splitting machines prevail among splitting machines (Tajboš and Lukáč 2015).…”

The size of wood is reduced by splitting or chipless cutting whilst logging trees, limbing, or preparing wood to be a fuel, for example, or in order to improve the efficiency of wood drying processes. Low costs of wood processing are desirable in each of these processes. The article presents experimental and simulation tests run in ABAQUS software, which allow for an analysis of the geometry of cutting tools used during the splitting or chipless cutting of wood in order to determine the cutting force and driving force of the machine executing such a process. The tests involved wood of Pinus sylvestris L. (moisture content: 8.74% ± 0.1%) in four configurations (chipless cutting transverse to the fibres (90°–90°), splitting along the fibres (0°–90°), splitting radially to the grain (90°–0°) and splitting tangentially to the grain (90°–0°)). Analysis of the force and strength of the blade proved that an effective tip angle of the knife blade falls between 30° and 45°. The presented results also suggested that splitting wood along the fibres (0°–90°) is preferable in a machine process, while splitting tangentially and radially to the wood grain (90°–0°) is preferable when splitting wood using manual tools.
