“…Among them, titanium and titanium based alloys are the most frequently used in biomedical applications. 10 Ti-6Al-4V has long been a main medical titanium alloy. It may be considered in any biomedical application, particularly for implantable components, because of its biocompatibility, good fatigue strength and low modulus.…”

“…4 Ti-6Al-4V is the most commonly used alloy; it is an extensively employed material for medicine, aerospace and other components that operate at high temperatures and in corrosive as well as hostile environments, such as aerospace and missile parts, gas turbine engines, steam turbines and chemical and petrochemical equipment. 5 In all these applications, resistance to fatigue, creep, corrosion and distortion depends on the characteristics of the machined surfaces. Titanium alloys are generally used for a component that requires the greatest reliability, and therefore, the surface integrity must be maintained.…”

Machined titanium components, such as medical prosthesis, require the greatest reliability, which is determined by process induced surface integrity. However, surface integrity of milled titanium components easily deteriorates due to the poor machinability of titanium alloys and cyclic chip loading during milling. Milling induced surface integrity, including anisotropic surface roughness, residual stress, surface microstructure alterations and microhardness, has received little attention. In the present study, a series of end milling experiments were conducted to comprehensively characterise surface integrity at various milling conditions of titanium alloy Ti–6Al–4V with TiAlN coated carbide cutting tools. The experiments were carried out under dry cutting conditions. For a range of cutting speeds, feeds and depths of cut, analyses of machined surface roughness, residual stress, microhardness and the microstructural observations were carried out. The present work aims to evaluate the influence of different milling conditions on workpiece surface integrity.

“…Titanium, Aluminum, the absence of thermal distortion, high flexibility, small cutting forces and being environmentally friendly. Due to these capacities, this cutting technique is more cost-effective than traditional and non-traditional machining processes [1][2][3][4][5][6][7][8][9]. The mechanism and rate of material removal during the AWJ cut depends on both the type of abrasive and the range of process parameters.…”

Process capability analysis is frequently employed to evaluate if a product or a process can meet the customer’s requirement. In general, process capability analysis can be represented by using the process capability index. Until now, the process capability index was frequently used for manufacturing processes with quantitative characteristics. However, for a process with qualitative characteristic like cutting surface, the data’s type and single specification caused limitations of using the process capability index. Taguchi developed a surface quality by abrasive water jet cutting or quadratic quality loss function to address such issues. In this study, we intend to construct a measurable index which incorporates the process capability index philosophy concept to analyze the process capability with the consideration of the qualitative surface roughness. The manufacturers can employ the proposed index to self-assess the process capability. The objective of this study was to examine the effects of abrasive water jet machining variables like cutting speed of the stainless steel material. The roughness of the varied surface through the cut depth was also measured and determined as a process capability index of 3 zones machined surface.
