Quality of machined surfaces and specific cutting energy in wood of two African mahogany species

Abstract: A escassez de informações sobre as características das madeiras de mogno africano e de sua trabalhabilidade limitam sua utilização e introdução no mercado madeireiro. Os objetivos foram avaliar a qualidade da superfície usinada e comparar o consumo de energia específica de corte entre as espécies das madeiras de Khaya ivorensis e Khaya senegalensis com diferentes padrões de usinagem. Para avaliar a qualidade da superfície usinada, foi utilizada uma desempenadeira com rotações de 2400, 3600 e 4000 min-1 e veloc… Show more

“…Surface quality was assessed immediately after machining by visual-tactile analysis, stylus surface profilometer reading, and feed per tooth (fz) measurement. These methods were adopted because they are widely used in industry (Coelho et al 2011) and by researchers (Andrade et al 2018;Braga et al 2014;Dias Júnior et al 2013;Malkoçoglu 2007;Martins et al 2011;Ramananantoandro et al 2014;Silva et al 2016) to assess surface quality. For all methods, the analyses were carried out at the same points, in three different positions of the boards: at half-length and 100 mm from each end).…”

“…On the other hand, Ramananatoandro et al (2014) stated that Ra is by far the most common parameter for surface quality ranking. Indeed, some authors have used only this roughness parameter (Hernández and Cool 2008;Dias Júnior et al 2013;Lopes et al 2014;Kvietková et al 2015;Andrade et al 2018;Darmawan et al 2020). The reason is that Ra is displayed on most stylus surface profilometers, as well as other devices, and is easily interpreted (representing the arithmetic mean roughness).…”

“…Neste contexto, a avaliação da energia específica de corte é muito importante para garantir que as máquinas sejam eficientes no processamento mecânico, sem desperdícios energéticos. Isso porque, os principais problemas enfrentados pela indústria madeireira, geralmente estão vinculados aos altos gastos com energia e as constantes paradas de produção devido à ultrapassagem dos limites de potência nominal dos motores elétricos (ANDRADE et al, 2018).…”
