Abstract

The present study aimed to evaluate the quality of the machined surface of wood of Peruvian Amazonian species under industrial processing conditions. For this, planks of capirona (Calycophyllum spruceanum), cachimbo (Cariniana domestica) and copaíba (Copaifera paupera) were obtained from which four specimens of each species were removed and selected. The specimens were previously conditioned and subsequently submitted to planing and sanding operations, considering three cutting orientations (tangential, radial and intermediate). Then, the quality of the flattened and sanded surfaces of the studied species was evaluated by measuring the surface roughness (Ra) by means of a digital needle detection roughness meter. The results indicated significant differences in wood surface quality among the species in the three evaluated cutting planes, and the capirona radial plane had better planing and sanding quality. Concomitantly, due to the operations performed, the capirona wood allowed a greater possibility for better finishing, followed by cachimbo and copaíba wood, thus being grouped in the 1st, 2nd, and 3rd surface quality classes, respectively.

Highlights

One of the key factors to consider for introducing new species to the market is the machining operations used during the finishing step aiming at a surface quality of wood products
Knowledge of wood properties and the establishment of criteria related to machining operations must be considered, and it is important and advisable to apply procedures that improve surface quality, and enable product economics during surface finishing in the manufacture of elaborate or semi-elaborated as is the case of furniture (SILVA et al, 2009; DIAS JUNIOR et al, 2013)
Aspects such as fine texture described by Acevedo and Kikata (1994) in capirona wood, give low roughness, in relation to The medium and heterogeneous texture described by the same authors in the cachimbo and copaíba woods contributed to the difference in the surface roughness of the woods

Summary

Introduction

One of the key factors to consider for introducing new species to the market is the machining operations used during the finishing step aiming at a surface quality of wood products. The quality required by the wood surface is defined by the specific requirements related to the end use of a product, influencing its commercial value. Knowledge of wood properties and the establishment of criteria related to machining operations must be considered, and it is important and advisable to apply procedures that improve surface quality, and enable product economics during surface finishing in the manufacture of elaborate or semi-elaborated as is the case of furniture (SILVA et al, 2009; DIAS JUNIOR et al, 2013).
