“…12,13 Other alternatives from the morphological matrix enable emissions reduction: the flying wing and laminar flow technologies to reduce drag and finally advanced composites for weight savings. 14,15,16 One of the functions of the morphological matrix is to reduce noise around airports. This can be satisfied by reducing the approach speed, or by using fairings around the landing gear to limit the number of interstices causing turbulence and thus noise.…”

New priorities in aircraft design are mapped out into an integrated holistic solution: an improved Green Taxiing system focused around the landing gear. The latter is streamlined through the use of fairings which also serve as landing gear doors. During the final approach phase, electric motors are used to rotate the wheels to the appropriate speed so as to reduce stress during touchdown. Energy, normally dissipated in heat, is collected in supercapacitors and used to power the aircraft subsystems for Green Taxiing. Titanium Matrix Composite is used to compensate additional weight. Super-capacitors power the aircraft during start and accelerations with engines turned off. For steady speed phase, the APU is used. An average 10 dB noise reduction is expected as well as a 4% decrease in operating costs and a 6% decrease in fuel consumption for a typical A320 mission.

“…Continuous fiber-reinforced MMCs have also been used in military applications, due to high specific strength, stiffness, and fatigue resistance. SiC monofilament reinforced Ti-matrix composites have been used as nozzle actuator controls for the F119 engine in F-16 [11]. The MMC replaced a heavier Inconel 718 in the actuator links and stainless steel in the piston rods [5].…”

I.INTRODUCTION Metal matrix composites (MMC) are a family of new materials which currently experiencing active development in various fields. The potential of MMC materials for significant improvements in performance over conventional alloys has been widely recognized. Besides performance, the other major factor in determining the applications for a material is cost. Raw materials cost is not the only factor determining the overall cost effectiveness of the material in a particular component application. It also depends on the processes through which the material advances.

“…For example, the density of conventional TiMMCs is 4040 kg/m 3 , and the stiffness is 200 GPa. 1 Although very expensive, metal matrix composites (MMCs) are a new generation of materials which have proven to be viable in various fields such as biomedical and aerospace industrial. Finding the optimal tool replacement time in machining TiMMCs is important in order to decrease the scrapped products and thus the cost of machining, and/or to increase the tool life, and thus to increase the availability of the cutting tool.…”

Little practical results are known about the cutting tool optimal replacement time, specifically for machining of composite materials. Due to the fact that tool failure represents about 20% of machine down-time, and due to the high cost of machining, in particular when the work piece's material is very expensive, optimization of tool replacement time is thus fundamental. Finding the optimal replacement time has also positive impact on product quality in terms of dimensions and surface finish. In this article, two new contributions to research on tool replacement are introduced. First, tool replacement mathematical models are proposed. These models are used in order to find the optimal time to tool replacement when the tool is used under variable machining conditions, namely, the cutting speed and the feed rate. Proportional hazards models are used to find an optimal replacement function. Second, this model is obtained during turning titanium metal matrix composites. These composites are a new generation of materials which have proven to be viable in various industrial fields such as biomedical and aerospace, and they are very expensive. Experimental data are obtained and used in order to develop and to validate the proportional hazards models, which are then used to find the optimal replacement conditions.
