Resumo: The circular saw is a tool commonly used for wood processing. It may be presented at different models. Considering their specificities, they can generate different amount of waste. The objective of this study was to evaluate the generation of waste from Tectona grandis L. f. and Pinus caribaea var. hondurensis, processed with two saws of the multiple type (48 and 36 teeth) and one of the universal type (28 teeth). The cutting process followed in grain direction into ninety samples, 15 for each species and saw, until the sample was completely processed. The processing time was measured and the waste was collected in each operation. ANOVA and test of multiple comparison of averages were applied. The influence of the teeth number and type of saw on the amount of waste generated was verified. The universal saw was the one that generated the highest amount of waste. It reached up to 116% more than the multiple saw, that generated the lowest amount of waste (36 teeth). P. caribaea var. hondurensis generated 7% more waste and presented shorter processing time (22%), when compared to T. grandis.

O objetivo deste estudo foi avaliar a geração de resíduos de Tectona grandis L. f. e Pinus caribaea var. hondurensis, processadas com duas serras do tipo múltipla (48 e 36 dentes) e uma do tipo universal (28 dentes). Foram efetuados cortes a favor da grã em noventa corpos de prova, 15 para cada espécie e serra, até o processamento completo da amostra. Foi medido o tempo de processamento e coletado o resíduo em cada operação. A ANOVA e o teste de comparação múltipla de médias foram aplicados. Constatou-se a influência do número de dentes e do tipo de serra na quantidade de resíduos gerados. A serra do tipo universal foi a que gerou maior quantidade média de resíduos, resultando em 116% a mais em comparação com a serra múltipla que gerou menor volume de resíduos (36 dentes). P. caribaea var. hondurensis gerou 7% mais resíduos e menor tempo de processamento (22%), quando comparado a T. grandis.Embrapa Florestas2022-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/octet-streamhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/213810.4336/2022.pfb.42e202002138Pesquisa Florestal Brasileira; v. 42 (2022)Pesquisa Florestal Brasileira; Vol. 42 (2022)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/2138/1661Copyright (c) 2022 Carlos Eduardo Silveira da Silva, Carolina Nogueira Xavier, Amanda Arantes Junqueira, Osmar de Freitas Neves Junior, Paulo Cesar Leal de Carvalho, Adriana Cazelgrandi Torres, Alexandre Monteiro de Carvalhohttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSilva, Carlos Eduardo Silveira daXavier, Carolina NogueiraJunqueira, Amanda ArantesJunior, Osmar de Freitas NevesCarvalho, Paulo César Leal deTorres, Adriana CazelgrandiCarvalho, Alexandre Monteiro de2022-12-14T14:46:53Zoai:pfb.cnpf.embrapa.br/pfb:article/2138Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2022-12-14T14:46:53Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
