Abstract:

This study investigated the model and simulation of dynamic cutting forces for high speed end mills, performed frequency spectrum analysis of dynamic cutting forces, and propounded the model and failure criterion of high speed end mills with indexable inserts. According to results of modal analysis and stress field analysis, the safety prediction and experiment of high speed end mills for machining aluminum alloy were done. Results indicate that more teeth of cutter and greater cutting contact angle make the energy more dispersible, higher cutting speed and greater rake of cutter can depress d

For better selection of coated cutting tools, TiAlN (Ti50Al50N) and CrAlN (Cr50Al50N) coatings were deposited onto ball-nose and square end mills using arc evaporation, and their cutting performances were evaluated using steel workpieces of various hardnesses. In particular, cutting tests were performed on three types of workpieces, made from S50C, SKD61, and SKD11 steels, having Brinell hardness numbers of HB220, HRC40, and HRC60, respectively. The results of the cutting experiments were elucidated and discussed in terms of the mechanical properties and anti-oxidation resistances of the diffe

Abstract:

Evaluation of manufacturing process in milling by direct measurement of cutting force is considered to be effective comparing to indirect measurement of electricity. This paper proposed a new evaluation method of end-mills by the direct measurement of cutting force. Cutting forces were precisely obtained by a 3-component dynamometer during end milling. Each flute cutting forces was evaluated for two types of end-mills (non wear-out, wear-out) by wave patterns of cutting force. A distinctive difference in the two types of end-mills has been clearly seen. The effectiveness of the proposed evalua

Abstract:

Novel end mills with micro-scale structures have recently been developed to promote cutting performances with cutting forces, chip controls, and tool wears. However, the surface profiles are formed corresponding to the structures on the tool edges. The surface finishes, therefore, are worse than those of cuttings with straight edges of the end mills. This paper discusses surface profiles in milling with the structured tool and the cutter axis inclination. An analytical model is presented to simulate the surface profiles for the tool edge shape, the cutting parameters and the cutter axis inclin

The ball nose end mills are highly used for complex sculptured surfaces in 3-5 axes milling. The modeling of the cutting process using ball nose end mills is more complex than in the case of simple end mills due to the fact that the cutting speed varies continuously along the cutting edge. By tilting the cutting tool relative to the surface to be machined, the modeling is getting more complicated due to the large number of input variables.

The use of end-mills for machining low curvature surfaces is examined in relation to the more popular ball-mills. End-mills are shown to give a better match to the required surface geometry and hence reduce the number of surface passes required. They also have a much better efficiency of material removal and longer tool life. It is shown that the use of end-mills for curved surface work can typically reduce the overall cutting time by a factor of twenty-four.

Abstract:

In the paper, a static milling force model for variable pitch mills was built, and the milling forces were simulated. The resultant force and its frequency spectra of variable pitch mills were analyzed compared with that of uniform pitch mills. It is shown that the standard deviation (SD) of frequency spectra amplitudes for variable pitch mills is extremely lower than that of uniform pitch mills. Through simulation for SD of frequency spectra amplitudes affected by the different cutting parameters, a pitch angles distribution of variable pitch helix end mills with lower SD of frequency spectra

Abstract:

Cutting force is very important in predicting machining error, surface properties, and chatter vibration. Cutting process simulators based on cutting force models for ball end mill operations have been developed so far by a lot of researcher. This paper describes a new approach for determining cutting coefficients, which are indispensable in predicting cutting force, for cutting force models of ball end mills. The feasibility of the proposed method on cutting coefficient determination is demonstrated in this paper.

Abstract:

We would like to report on the development of our new ultra fine crystalline CVD diamond film and some applications. CVD Diamond films have good wear resistance, but the crystal size is too large. Therefore, in case of application of diamond films for cutting tools, we cannot get fine surface finish on work materials. Recently we succeed in production ultra fine crystalline CVD diamond film and various cutting tools as taps, drills and end mills. Aluminum alloys have lately been consumed more than ever in airplanes and automobiles for the purpose of decreasing the weight of structural material

Abstract:

This paper describes a method for generating toolpaths based on machining strategies for five-axis controlled machining using special tools. Traditionally, most toolpath generation studies focused on ball-end mills, proposing strategic methods to achieve high-quality machining while avoiding tool interference. Recently, special finishing tools with large cutting edge radii have gained interest for achieving higher machining efficiency. These special tools can produce smooth finished surfaces even with large pick-feed widths, leading to higher productivity. However, unlike conventional machinin

Abstract:

Cutting forces and machining error in contouring of concave and convex surfaces using helical ball end mills are theoretically investigated. The cutting forces are evaluated based on the theory of oblique cutting. The machining errors resulting from the tool deflections due to these forces are evaluated at various points of the machined surface. The influence of various cutting conditions and cutting modes on machining error is investigated and discussed.

Abstract:

The article deals with the tool life of ball nose end mills and surface roughness of steel C45 depending on up-copying and down-copying. The cemented carbide and high speed steel was used as tool material. Furthermore, the new and sharpened cutting tools were also compared. In the experiment, the cutting speed, feed rate, axial and radial depth of cut were not changed. The results show different achieved surface roughness of machined material C45 and tool life of ball nose end mills depending on the copy milling strategy for various tool materials.

Side milling tests of CFRP (carbon fiber reinforced plastics) containing thermosetting resin are carried out by TiAlN/AlCrN-coated, H2-free DLC (diamond-like carbon)-coated, and CVD diamond-coated carbide end mills without coolant. Two types of end mills having different helix angles of 30° and 60° are used. The film thickness and surface smoothness are varied for the DLC-coated end mills. The cutting characteristics are evaluated by tool wear and surface integrity (i.e., 3D profiles of the machined surface, generation of fluffing, delamination, and pull-out of the carbon fibers).

With all tools having similar cutting-edge radii (re) of ~6 µm, the feed rate was varied between 25–250 mm/min while the cutting speed and axial depth of cut were kept constant at 126 m/min and 100 µm, respectively.

High-quality cutting edge surfaces with roughness of magnitude 0.3–0.35 µm was achieved using the electro-polishing process. A direct current of 0.96 A was passed through an electrolytic cell containing the electrolyte sodium hydroxide with a concentration—2.5 mol/dm3.
