“…Experiments conducted by Kopac (1998), D'Errico et al (1999, Dolinsek (2001), Mativenga (2003) analysed the influence of tool coatings such as TiAlCN and TiN on tools wear and wear mechanisms during the machining of carbon steels and titanium alloys. In 2008, Ravindra and Pattern studied the surface quality of a chemically vapour-deposited (CVD) polycrystalline SIC material to be used in optics devices such as a mirror.…”

Tool life is an important factor to be considered during the optimisation of a machining process since cutting parameters can be adjusted to optimise tool changing, reducing cost and time of production. Also the performance of a tool is directly linked to the generated surface roughness and this is important in cases where there are strict surface quality requirements. The prediction of tool life and the resulting surface roughness in milling operations has attracted considerable research efforts. The research reported herein is focused on defining the influence of milling cutting parameters such as cutting speed, feed rate and axial depth of cut, on three major tool performance parameters namely, tool life, material removal and surface roughness. The research is seeking to define methods that will allow the selection of optimal parameters for best tool performance when face milling 416 stainless steel bars. For this study the Taguchi method was applied in a special design of an orthogonal array that allows studying the entire parameter space with only a number of experiments representing savings in cost and time of experiments. The findings were that the cutting speed has the most influence on tool life and surface roughness and very limited influence on material removal. By last tool life can be judged either from tool life or volume of material removal.

“…D'Errico et al [21] conducted a study on HSM using PVD cathodic arc system coatings of TiN þ TiCN, TiAlCN, TiCN, TiN, TiAlNbN, the uncoated cermet, and hard-metal substrate. Of relevance to this study was that machining AISI-SAE 1045 tool life improvements over the uncoated tool were as follows: TiAlNbN, 271 per cent; TiN þ TiCN, 297 per cent; TiCN, 385 per cent; TiAlCN, 453 per cent; TiN, 473 per cent.…”

This paper reviews the contributions that coatings make in enhancing the cutting performance of carbide tools and, in particular, their application in high-speed machining. It examines flank wear and cutting force process trends that are essential for monitoring tool degradation in automated machining factories. The findings of the investigation into cutting forces over the life cycle of different physical vapour deposition (PVD) tool coatings on micrograin carbide in the high-speed machining of tool steel are presented and related to the existing literature. Cutting tests were carried out at a very high spindle speed, 40 000 r/min, and for a predetermined cutting time. Variants of the TiAlN coating, i.e. single-and doublelayer and composite coating enhanced with WC/C, were evaluated against the uncoated tool and the TiCN, CrN, and TiN coatings. The paper reflects on the performance of advanced PVD coatings and also presents force trends and suggestions for process monitoring.

“…Previously [ 21 ], it was reported in many papers that report on the tool wear, deterioration of machined surface roughness due to the increase of cutting force, and the deterioration of machined surface quality due to the progress of tool wear in the machining of large diameter end mills such as 2 mm in diameter or more. G. E. D’Errico et al [ 22 ] studied tool wear during end milling [ 22 , 23 , 24 , 25 , 26 ]. D. A. Axinte et al [ 27 ] investigated machining qualities such as surface integrity after end milling [ 27 , 28 , 29 , 30 ].…”

The importance of micromachining using small diameter end mills and the dies used for them has been increasing in the machining of small parts. However, the reality is that there are various requirements to improve the machining surface, machining accuracy, machining efficiency, and tool life. Therefore, this paper discusses the possibility of satisfying these requirements by high-speed up cut milling in side cutting. The goal of this study was to solve the aforementioned problems, by conducting a detailed analysis of the machining phenomena in order to understand their mechanisms. In particular, the effects of high-speed cutting using a high-speed air-turbine spindle with highly stiff rolling bearings were analyzed. Moreover, cutting experiments were conducted by measuring the cutting force and flank wear of the tool, to reveal the differences in the cutting phenomena relative to the cutting direction in high-speed micro end milling. Description of the machined surface and the measurement of its profile were also included in the discussions. On the basis of the results, high-speed up cut milling is a better choice than down cut milling; furthermore, a high-feed rate further increases machining efficiency and improves tool life.
