Effects of geometric angle and cutting speed on cutting forces and tool wear of ceramic cutting tools during peripheral up‐milling of high‐density fiberboard

Abstract

In this paper, cutting forces and tool wear of ceramic cutting tools are investigated by up-milling high-density fiberboard under different geometric angles and cutting speeds. The results show that tangential force (F t ) and normal force (F r ) decrease with the increase of rake angle. The values of F t and F r at the higher speed cutting condition are lower than that at the lower speed condition. The flank wear (VB) declines with increased clearance angle and decreased cutting speed. The tool wear patterns observed on the ceramic cutting tools are pull-out of grain, cracking, tipping, and flanking. Abrasive wear and adhesive wear are the main mechanisms of the ceramic cutting tools. In all, on the premise of guaranteeing the ceramic cutting tools' strength, the ceramic cutting tool with a bigger rake angle and clearance angle is advisable in high-density fiberboard machining, in terms of lowering the energy consumption and production cost required for machining.

Wheat straw pre-treatments using eco-friendly strategies for enhancing the tensile properties of bio-based polylactic acid composites

“…The results revealed that the presence of pre-treated straw in bio-based composites induces a negligible reduction in density compared to that of bio-based composites with untreated straw. The term high-density fibreboard composites refers to the composites with the density higher than 0.8 g/cm 3 (Guo et al, 2020;Mamiński et al, 2018). In this study, the density values of all the bio-based composites have been varied between 0.92 g/cm 3 and Fig.…”

Effects of Tool Tooth Number and Cutting Parameters on Milling Performance for Bamboo–Plastic Composite

“…This requires the workers to stop the machine and change the tool to continue production. Thus, tool wear is an important factor affecting productivity, surface quality, and machining cost [31,32]. According to one study [33], tool wear mainly depends on the generation of force and temperature during cutting processes.…”

The Application of Tribological Tests to Study the Wear Behavior of Asphalt Cutter Teeth: An Experimental Investigation Using Baroid Tribometer

“…Studies in the field have analyzed the interaction between milling drum teeth and asphalt layers. The research papers [6][7][8][9][10][11][12][13] provide information and results focused, mainly, on the aspects related to how the dislocation of asphalt concrete components (mixture of aggregates and filler/bitumen in solid state) occurs under the action of the cutter teeth, while the specialized literature [14][15][16][17][18][19][20][21] investigates the effect of the milling process on the milling teeth. The experimental research [14] evaluated, through statistical analysis, the wear process of teeth from two different manufacturers.…”

“…Guo et al [19] examined the cutting forces and tool wear of ceramic cutting tools when up-milling high-density fiberboard at varying geometric angles and cutting speeds, and proposed to use larger rake angles and clearance angles to decrease the tool wear.…”
