“…Similar to the results of Guo et al [6] and Zhu et al [22], the surface roughness decreased with the increase of spindle speed and increased with an increased cutting depth ( Figure 5). As expressed in Equations (5) and (6), the increasing spindle speed and decreasing cutting depth reduced the feed per tooth and the cutting thickness during the milling process, directly lowering the resistance acting on the cutter and improving the cutting stability. Thus, the cutting quality was improved by increasing the spindle speed and decreasing the cutting depth.…”

“…During cutting, the unwanted material above the cutting layer was removed by the rake angle and formed into chips. The chip volume, namely, removal quantity, was directly determined by feed per tooth and cutting thickness, as expressed by Equations (5) and (6) [15].…”

“…Glass MGO board is a difficult-to-cut material due to its high hardness, which easily increases the wear rate of cutters. In practical production, common cutter materials, such as high-speed steel [4], tungsten carbide [5], and ceramic [6], cannot meet the requirements of glass MGO board machining. Considering the circumstances, diamond cutters appear to be the best choice to deal with this problem [7].…”

In this paper, the effects of tool geometry and cutting parameters on cutting force and quality were investigated during the tapered milling of glass magnesium (MGO) board with diamond cutters. The results were as follows: firstly, both the cutting force and roughness of the machined surface were positively correlated with the taper angle of the cutters and the cutting depth, but negatively related to the spindle speed. Then, the cutting depth had the largest influence on the cutting force and surface roughness, followed by the taper angle and spindle speed. Thirdly, the taper angle had a significant influence on the cutting force, but not on the surface roughness. The contribution of the spindle speed to both the cutting force and the surface roughness were significant, while the cutting depth had an insignificant effect on the cutting force and the surface roughness. Finally, the optimal cutting condition for the tapered milling of glass magnesium board was found to be a taper angle of 15°, a spindle speed of 5000 rpm (cutting speed of 36.63 m/s), and a cutting depth of 0.5 mm, which are proposed for industrial production in order to achieve greater cutting quality and economic benefit.

“…In the face of this difficult-to-cut material, diamond cutting tools appear to be the best choice [6]. Compared with other common cutter materials, such as cemented carbide [7] and ceramics [8], diamond cutting tools offer outstanding advantages. These include their low thermal expansion coefficient [9], high hardness [10], low friction coefficient [11], and high thermal conductivity [12].…”

This paper investigated the machinability of a stone–plastic composite (SPC) via orthogonal cutting with diamond cutters. The objective was to determine the effect of cutting depth on its machinability, including cutting forces, heat, chip formation, and cutting quality. Increased cutting depth promoted an increase in both frictional and normal forces, and also had a strong influence on the change in normal force. The cutting temperatures of chips and tool edges showed an increasing trend as cutting depth increased. However, the cutting heat was primarily absorbed by chips, with the balance accumulating in the cutting edge. During chip formation, the highest von Mises strain was mainly found in SPC ahead of the cutting edge, and the SPC to be removed partially passed its elastic limit, eventually forming chips with different shapes. Furthermore, the average surface roughness and the mean peak-to-valley height of machined surfaces all positively correlated to an increase in cutting depth. Finally, with an increase in cutting depth, the chip shape changed from tubular, to ribbon, to arc, to segmental, and finally, to helical chips. This evolution in chip shape reduced the fluctuation in cutting force, improving cutting stability and cutting quality.

“…Currently, cemented carbide is the most widely used material in woodworking tools. Super-hard ceramics [12], coating technologies[13,14], and the optimization of the cutting tool structure[15] are commonly used to reduce the coefficient of friction. Micro-textures can improve material friction performance[16,17] and they have been applied in friction between the wood and metal[18], and mainly considering the effect of moisture content of wood and loading on friction coefficient.…”

A reasonable micro-pits texture has been initially proved that it can improve friction characteristics between wood and cemented carbide surface and reduce surface friction coefficient. In order to study the cutting performance of the micro-texture when it is applied to the cutting tool for cutting wood more effectively, this paper selected micro-pit texture for studying influence of surface micro-texture cutting tool on wood cutting performance and cutting temperature, finding that when micro-pit cemented carbide cutting tool is adopted for turning the northeast China ash ( Fraxinus spp.), it can reduce cutting force of turning and surface friction coefficient between rake face and cuttings. Moreover, for type A and type B cutting tools, when the texture parameters are that the diameter of the micro-pit is 80μm, the depth of the micro pit is: 10μm, area occupancy is 20% and the diameter of the micro-pit is 120μm, the depth of the micro-pit is 10μm and the area occupancy is 20%, the effect generated is the best. When a texture cutting tool is used for cutting, the decrease of the highest temperature in the cutting area is not very great, but the average temperature in the cutting area changes a lot, which is mainly caused by that micro-texture is processed at a position of the rake face close to the main cutting edge and that the highest temperature of cutting is mainly generated on the contact point between tool tip and wood. A reasonable micro-texture parameter can form a layer of liquid lubricating film on the up and down contact surfaces such that the direct contact between cemented carbide and northeast China ash is changed into indirect contact between lubricating films formed by the liquid so as to reduce the surface friction coefficient.
