Abstract:
The present study deals with tapping of Al6061/SiC metal matrix composite. Stir casting technique was used for the fabrication of composite. Castings were produced by varying weight percentages of SiC (5%, 7.5% and 10%) of 23μm size in Al6061. The tapping experiments were conducted for the machinability study of Al6061/SiC metal matrix composite using M8 x 1.25 HSS machine taps. The tapping operation was performed under dry condition with different cutting speeds. Torque required for tapping was measured using piezoelectric based 4-component drill tool dynamometer.

In the manufacturing of metal components both wear and corrosion have to be considered. In particular, corrosion is a primary problem in the aeronautic field, where the aluminium alloys are affected by several corrosion typologies. Furthermore, nowadays carbon fibre reinforced plastics (CFRP) are finding an increasing use, but they can induce galvanic corrosion phenomena when coupled with aluminium alloys. To overcome this problem, corrosion resistant coatings are used on aluminium components. On these premises, the realization of a titanium coating on aluminium components could allow the coup

However, fine blanking as a forming process changes the microstructure of the metal sheet to a higher extend than cutting or machining processes.

Abstract:
This chapter describes how corrosion is the degradation of a material due to a reaction with its environment. Wear is another deteriorating phenomenon which erodes the contacting surfaces of any mechanical component gradually. Although corrosion and wear are two different phenomenon they are often interdependent and in most practical situations take place simultaneously. Fortunately, several surface modification methods exist which can protect the surface of metal against corrosion and wear. Among them, electroless nickel coatings is a technology where a coating is applied without the use of external current source. The primary advantages of electroless coatings include uniform coating and ability to coat non-conductive materials. Electroless nickel coatings possess excellent properties such as high hardness, good wear resistance and corrosion resistance. The corrosion and wear behavior of these coatings mainly depend on bath ingredients, deposition conditions, heat treatment temperature, etc.

Abstract:
Woodworking is based on a trinomial machine/piece/tool. For maximum quality of the manufactured piece, it is important not to separate this trinomial, but the limited life of tools prevents that permanent contact. This phenomenon is due to the wear of the cutting parts of the tools. The prevention of wear is based on two methods. The first is to anticipate the end point of tool wear, changing these after a fixed period, no matter what. The other school is to recognize the tool wear at the event: the tools are changed once they are really worn out, finding faults on manufactured parts. A worn tool generates pieces with non-compliant quality or even unusable. A deeper understanding of wear and its consequences would change the tool at the right time. The tool wear for wood is due to several phenomena interacting with each other. The first dominating phenomenon is a corrosive attack that decreases the mechanical strength of the surface. The second is an abrasive attack whose work is facilitated by the reduced resistance of the surface. Repeated shocks can be in the degradation of the cutting edge, temperature acting as amplifier to wear. Understanding of the wear patterns can characterize the life of tools by wear measurement to find ways to extend this period with development of tool coatings, while maintaining optimal conditions for woodworking to get the best finish.
