Abstract

The Indonesian furniture industry holds significant potential in the global market, contributing 1.16% to GDP in the first quarter of 2024. This study aims to analyze the effects of cutting methods and feed rates in CNC milling on dimensional accuracy and surface roughness of High Moisture Resistant (HMR) engineered wood. The experiment was conducted using a Completely Randomized Design (CRD) with statistical analysis through Analysis of Variance (ANOVA). Treatments included conventional and climb cutting methods, as well as feed rates of 33 mm/s and 66 mm/s, applied to specimens measuring 50 mm × 35 mm × 18 mm with a cutting depth of 4 mm. Results indicate that cutting methods significantly affected specimen length, width, and surface roughness (P-value < 0.05; F > F critical). However, microstructural observations revealed that cutting methods did not significantly influence surface roughness. Feed rate showed no significant effect on specimen length or surface roughness (P-value > 0.05; F < F critical), but significantly affected specimen width (P-value < 0.05; F > F critical). Conversely, microstructural analysis demonstrated that feed rate influenced surface roughness. Overall, cutting method was identified as the dominant factor affecting dimensional accuracy and surface roughness of HMR, while feed rate had greater influence on specimen width and microstructural surface conditions.

Abstract

This study aims to evaluate the strength of conventional and innovative joints in MDF furniture construction through compression testing. The four types of corner joints tested include Lamello biscuit joints, Minifix joints, wood dowel joints, and JCBC insert nut joints. Each joint type was tested under two loading conditions using the diagonal compression method. Test results indicate that the futuristic JCBC insert nut joint and the conventional wood filler joint exhibited the highest compressive strength, while the futuristic Minifix joint and the conventional Lamello biscuit joint demonstrated the lowest compressive strength performance under both the A-shaped and L-shaped test configurations. Statistical analysis of the density and moisture content of the MDF revealed no significant differences among all specimens; thus, the differences in compressive strength were primarily influenced by the type of joint. These findings provide practical recommendations for the furniture industry in selecting the optimal joint based on efficiency and structural strength, with wood fillers (conventional joints) used for knock-up furniture and JCBC insert nuts (futuristic joints) used for knock-down furniture as the best alternatives for furniture construction joints.
