Analysis of Drilling Behaviour in Jute Fibres Reinforced Natural Composites

In the study, Natural jute composite materials, which have environmental advantages due to their easily degradable nature were drilled with different processing parameters and the effects of thrust force, vibration and temperature changes on hole quality were investigated. The effect of feed and spindle speed was statistically analyzed using ANOVA method. The thrust force, vibration and temperature factors that occur depending on the drilling parameters vary and affect the roughness and delamination values. The effect of feed and speed on thrust force was calculated as 97.87% and the feed effect (90.85%) is far greater than the speed (9.15%). The effect of drilling parameters on vibration is statistically insignificant due to the different spread behavior in the layers of the composite material (R2 = 0.2329). However, feed effect on vibration (94.6%) is greater than the speed effect (6.06%). The temperature is affected by 96.93% of the drilling parameters and the speed is 84.16% and the feed is 15.83%. The roughness effect depending on the drilling parameters is measured as 84.91%. The effect of speed on roughness (90.26%) is greater than the feed (9.73%). It has been determined that this situation is mostly related to vibration and temperature.

Automated summary

In this study, the effects of thrust force, vibration, and temperature changes on hole quality were investigated for natural jute composite materials. The statistical analysis using ANOVA method revealed that feed had a significantly greater impact on thrust force compared to spindle speed. Vibration was found to be largely affected by feed, while temperature was influenced by both feed and speed. Additionally, it was observed that roughness was mainly influenced by speed, vibration, and temperature.
