Prediction of cutting forces in machining of metal matrix composites
This paper presents a mechanics model for predicting the forces of cutting aluminum-based SiC/Al2O3 particle reinforced MMCs. The force generation mechanism was considered to be due to three factors: (a) the chip formation force, (b) the ploughing force, and (c) the particle fracture force. The chip formation force was obtained by using Merchant’s analysis but those due to matrix ploughing defo...
متن کاملThe Effect of Surface Roughness of End-Mills on Optimal Cutting Performance for High-Speed Machining
Developments in machine tools tend towards high speed technology, including high-speed machining (HSM) and high-speed cutting (HSC), especially in high speed end milling applications [1] and [2]. High speed technology applications in machine tools are characterised by a high feeding speed, low axial and radial cutting depth, increased metal removal rate, simplified processing, and reduced costs...
متن کاملinvestigation of machining parameters in wire electrical discharge machining (wedm) on the surface roughness & cutting speed of tungsten carbide
surface roughness is one of the most important parameters that plays very critical role in determining the quality of engineering components. a good surface quality resulting in improve of fatigue strength, corrosion and wear resistance of the workpiece. on the other hand, increasing cutting speed and decreasing time of machining are desirable for manufacturers in order to reduce costs and incr...
متن کاملMachining with Minimal Cutting Fluid
The purpose of cutting fluid in a machining operation is to cool the workpiece, reduce friction, and wash away the chips. The cutting fluid contributes significantly toward machining cost and also possesses environmental threats. In the past, there have been some attempts to minimize the amount of cutting fluid in machining. This chapter reviews some prominent ways to minimize the application o...
متن کاملHigh Speed Thin Metal Cutting using Fiber Laser Technology
There are several methods available for precision cutting of thin metals less than 0.06-inch thick used for these applications, which include materials such as stainless steel, titanium, nickel, and aluminum. The major options, lasers, electric discharge machining (EDM), water-jet, and chemical machining each have a role to play. However, precision fiber laser cutting technology is now emerging...
