Investigation of the Effect of Machining Parameters on Surface Quality in Bamboo

Abstract

The purpose of the study is to obtain optimum processing conditions by investigating the effect of machining parameters of bamboo (Bambusa) material on surface quality. Evaluation was performed for four machining parameters (cutters type, spindle speed, feed rate and depth of cut) and their effects on surface roughness. According to obtained data, roughness values increased with increasing machining depth. Increase in roughness values between 8000 rpm and 10000 rpm, decrease in roughness values between 10000 rpm and 14000 rpm, and increase in roughness values between 14000 rpm and 16000 rpm was observed. Roughness value increased with increasing cutter feed speed. Roughness value decreased by increasing number of blades in cutter in cutter type. The lowest roughness value was obtained at a machining depth of 2 mm at a spindle speed of 14000 rpm, a feed rate of 1000 mm/min and a cutter type 3 (four flute spiral end mill).

Determination of processing characteristics of wood materials densified by compressing

“…It is seen that Ra value increases as the feed rate increases and it creates a statistically significant difference (P = 0,004). In the literature, it was stated that roughness values increase as a general tendency as the feed rate increases in the processing of wood and wood-based materials (Aykac and Sofuoglu 2021, Bal 2018, Bal and Akçakaya 2018, Davim et al 2009, Hazir et al 2018, Ilter et al 2002, Isleyen and Karamanoglu 2019, Karagoz 2010, Koc et al 2017, Pinkowski et al 2018, Sutcu and Karagoz 2012, Sofuoglu et al 2022. It seems that the data obtained in the study are compatible with the literature.…”

“…While there was a slight decrease in the Ra value with the increase of speed from 12000 rpm to 15000 rpm, the decrease was higher with the increase of the speed from 15000 rpm to 18000 rpm. With the increase in the speed in rotary cutting cutters, roughness values decrease and smoother surfaces can be obtained (Aykac and Sofuoglu 2021, Davim et al 2009, Hazir et al 2018, Isleyen and Karamanoglu 2019, Karagoz 2010, Koc et al 2017, Sofuoglu 2015, Sutcu and Karagoz 2012, Sutcu and Karagoz 2013. It is seen that the data obtained in the study show similar trends with the literature.…”

“…With the increase in the number of revolutions in rotary cutters, roughness values decrease, and smoother surfaces can be obtained (Karagoz, 2010;Sutcu and Karagoz, 2012;Sofuoglu, 2015a;Sofuoglu, 2015b;Koç, et al, 2017;Hazır, et al, 2018;Aykac and Sofuoglu, 2021;Tosun, 2021). When evaluated in general, it is seen that the values obtained in the study show similar trends to those in the literature.…”
