摘要

本研究的主要目的是确定热处理对实木材料加工性能的影响,并确定最佳切削参数,以获得表面粗糙度最小的表面。为了实现这一目标,选择了广泛用于木工和家具行业的西伯利亚松(Pinus sibirica)木材作为实验材料。热处理(在190°C的温度下持续2小时)和未处理的样品使用两种不同的刀具(硬质合金上切铣刀和硬质合金压缩铣刀)进行机加工,刀具直径为5 mm,进给速度为1000、1500和2000 mm/min,主轴转速为8000、12000、16000 rpm,在CNC机床上分别为50、75和100%。根据ISO 468(2009)、ISO 3274(2005)和ISO 4287(1997),使用接触式轮廓仪测量表面粗糙度值(Ra和Rz)以评估所获得的表面。当对数据进行总体评估时,Ra的最低粗糙度值出现在上切铣刀中,在未处理的实木材料上进给50%的步进、12000rpm、1000mm/min。Ra的最高粗糙度值出现在压缩铣刀中,在热处理的实木材料上进给100%步进、16000转/分、2000毫米/分钟。已经观察到,进给是影响表面粗糙度的最关键的参数。

Određivanje svojstava obradivosti toplinski modificiranog drva sibirskog bora (Pinus sibirica)
The main objective of this study is to determine the effect of heat treatment on the machiningproperties of solid wood material and determine the optimum cutting parameters to obtain surfaces with minimum surface roughness. In line with this goal, Siberian pine (Pinus sibirica) wood species, widely used in the woodworking and furniture industry, was chosen as the experimental material. The heat-treated (at a temperature of 190 °C for 2 hours) and untreated samples were machined using two different cutters (carbide upcut milling cutter and carbide compression milling cutter) with 5 mm diameter at 1000, 1500 and 2000 mm/min feeds, 8000, 12000, 16000 rpm spindle speed, 50, 75 and 100 % stepover on the CNC machine. Surface roughness values (Ra and Rz) were measured to evaluate the obtained surfaces according to ISO 468 (2009), ISO 3274 (2005), and ISO 4287 (1997) using a contact profilometer. When the data was evaluated in general, the lowest roughness value for Ra occurred in upcut milling cutter, with 50% stepover, 12000 rpm, 1000 mm/min feed on untreated solid wood material. The highest roughness value for Ra occurred in a compression milling cutter, with 100 % stepover, 16000 rpm, 2000 mm/min feed on heat-treated solid wood material. It has been observed that the feed is the most critical parameter affecting the surface roughness.
