The results of orthogonal cutting tests carried out on unidirectional glass fiber reinforced plastic composites, using HSS tools, are presented and discussed. During the tests, performed on a milling machine at very low cutting speed to avoid thermal effects, the cutting speed was held constant and parallel to the fibre direction. Three parameters, namely the tool rake angle α, the tool relief angle γ, and the depth of cut t, were varied. According to the experimental results, the horizontal force per unit width, Fhu, undergoes a dramatic decrease, never verified for metals, with increasing α.

Annealed metals are surprisingly difficult to cut, involving high forces and an unusually thick “chip.” This anomaly has long been explained, based on ex situ observations, using a model of smooth plastic flow with uniform shear to describe material removal by chip formation. Here we show that this phenomenon is actually the result of a fundamentally different collective deformation mode—sinuous flow. Using in situ imaging, we find that chip formation occurs via large-amplitude folding, triggered by surface undulations of a characteristic size. The resulting fold patterns resemble those observ

The cutting of metals has long been described as occurring by laminar plastic flow. Here we show that for metals with large strain-hardening capacity, laminar flow mode is unstable and cutting instead occurs by plastic buckling of a thin surface layer. High speed in situ imaging confirms that the buckling results in a small bump on the surface which then evolves into a fold of large amplitude by rotation and stretching. The repeated occurrence of buckling and folding manifests itself at the mesoscopic scale as a new flow mode with significant vortex-like components—sinuous flow. The buckling m

Downsizing energy consumption during the machining of metals is vital for sustainable manufacturing. As a prerequisite, energy consumption should be determined, through direct or indirect measurement. The manufacturing process of interest is the finish turning which has been explored to generate (near) net shapes, particularly for hardened steels. In this paper, we propose using measured cutting forces to calculate the electrical energy consumption during the finish turning process of metals where typically the depth of cut is lower than the cutting tool nose radius.

Maximum force is required at the end of the ridging period and at the beginning of cutting. Since one of the blades is stationary, the second blade in cutting process has to go deep into the entire thickness of metal to cut the billet. For example, if thickness of metal is20 mm, then the upper blade needs to pass20 mmfor its cutting. If you make both blades moving towards each other, cutting eﬀort will be less.

The machining of cellular metals has been a challenge, as the resulting surface is extremely irregular, with torn off or smeared material, poor accuracy, and subsurface damage. Although cutting experiments have been carried out on cellular materials to study the influence of cutting parameters, current analytical and experimental techniques are not suitable for the analysis of heterogeneous materials. On the other hand, the finite element (FE) method has been proven a useful resource in the analysis of heterogeneous materials, such as cellular materials, metal foams, and composites. In this st

The development of technology in recent years, as well as the need to obtain high precision surfaces and in the shortest possible time, has led to the search for new cutting methods. CNC machine tools show high productivity, high precision pieces can be obtained from one or two positions, and materials with high hardness can be processed. Milling is a manufacturing process that allows the processing of flat surfaces and complex surfaces. In recent years, numerous studies have been carried out regarding the milling processing of hard materials. This paper presents a short review regarding the r

Additively manufactured parts have recently been applied to products in aerospace, automobile, and tool industries in terms of design flexibility and material consumption with mechanical strength. Because the surfaces of additively manufactured parts are coarse, milling is conducted as a post-process to achieve fine surfaces within the specified tolerance. However, the microstructures and the mechanical properties of additively manufactured metals differ from those of wrought metals. Therefore, the cutting characteristics should be understood to determine the appropriate cutting parameters. Th

This paper deals with the lubricating action of nonmetallic inclusions in metal cutting. The purpose of this study is to find the most effective inclusions for metal cutting, and to develop free machining sintered metals including nonmetallic materials. The most effective additives are glass, boron nitride, and talc. By the addition of 3 percent glass to the iron, tool life could be increased 60 times.

The analysis of the influence of various technological solutions used in the thermal cutting of heavy-gage sheet metals to reduce the deformations of the resulting piece parts is given. It has been suggested to use a gas-oxygen cutting technology with packing sequence without localization of heat build-up. The effect of improving the efficiency and quality of production using the developed cutting technology is shown.

This paper describes the experiment of measuring the temperature and cutting force during the drilling of short holes without using cutting lubricants, at constant cutting speed, and at increasing shift. Measurement was performed on steel samples of grade 11 523. During drilling, temperature was monitored by a thermocouple, using the method of two foreign metals. Cutting force was measured by a strain-gauge sensor. The experiment provides a quick orientation in the given issue and points out to the optimisation of cutting conditions. Based on results, it can be stated that the range of tempera

This paper deals with the effect of cutting speed on chip fracture strain in high speed cutting. Firstly, a chip-fracture-strain-measuring device is designed and made according to chip breaking principle. Secondly, experiments are performed by the chip-fracture-strain-measuring device. The experiment results show that chip fracture strain increases first and then diminishes as cutting speed increasing in high speed cutting while feedrate and depth of cut are constant values. Lastly, the effect of cutting speed on chip fracture strain is theoretically analysed from three main factors which affe
