new Machinability study of glass fibre reinforced plastics using polycrystalline diamond and cemented carbide k15 tools
Materials & Design, 2007Co-Authors: Paulo J Davim, Francisco MataAbstract:Abstract The Machinability refers to the ease or difficulty with which a given composite material can be machined. It is very important to understand the factors affecting the Machinability and to evaluate their effects. This paper aims to investigate the Machinability in turning processes of glass fibre reinforced plastics (GFRP’s) manufactured by hand lay-up. A plan of experiments was performed on controlled machining with cutting parameters prefixed in workpiece. A statistical technique, using orthogonal arrays and analysis of variance (ANOVA), has been employed to know the influence of cutting parameters on specific cutting pressure and surface roughness. The objective is to evaluate the Machinability of these materials in function of cutting tool (polycrystalline diamond and cemented carbide tools). A new Machinability Index has been proposed.

a new Machinability Index in turning fiber reinforced plastics
Journal of Materials Processing Technology, 2005Co-Authors: Paulo J Davim, Francisco MataAbstract:Abstract This article presents a study on the Machinability in turning processes of fiber reinforced plastics (FRPs) using polycrystalline diamond cutting tools. Controlled machining experiments was performed with cutting parameters prefixed in the workpiece. A statistical technique, using orthogonal arrays and analysis of variance, was employed to investigate the influence of cutting parameters on specific cutting pressure and surface roughness. The objective is to evaluate the Machinability of these materials as a function of manufacturing process (filament winding and hand lay-up). A new Machinability Index has been proposed.

Identification of the role of Machinability and milling depth on machining time in controlled depth milling using abrasive water jet
The International Journal of Advanced Manufacturing Technology, 2013Co-Authors: Puneet TandonAbstract:Abrasive water jet machining (AWJM) is mainly used to through cut materials that are difficult to cut by conventional machining processes. This process may also be used for controlled depth milling (CDM) of materials. This work focuses on making blind pockets of controlled depths for a set of materials with AWJM. The materials used in the present work are AL 6061 alloy, AL 2024, brass 353, titanium (Ti6Al4V), AISI 304 (SS), and tool steel (M2 Rc 20). The effects of the milling depth and material characteristics on milling time are investigated. It is observed that Machinability Index and mechanical properties of the materials milled play important role in establishing milling time and surface roughness. It is found that traverse speed of AWJ process is lower for the materials with low Machinability Index and vice versa. Besides, the milling time increases non-linearly as the depth of milling increases due to loss of energy of jet and increase in standoff distance (SOD).

composite cutting with abrasive water jet
Procedia Engineering, 2013Co-Authors: Amaia Alberdi, Alfredo Suarez, T Artaza, Gustavo Escobarpalafox, Keith RidgwayAbstract:Abrasive Water Jet (AWJ) technology has demonstrated to be an interesting manufacturing process for space, aircraft, boat and automotive sectors due to its specific advantages when machining composite materials. However, AWJ cutting of composite laminates possesses several challenges. It is necessary to develop a methodology to adapt the process parameters for each type of FRP & CFRP material which will allow AWJ trimming operations to be easily carried out on composite materials, since machine manufacturers still do not provide good databases for composite cutting. The presented work aims at studying the behaviour of a Machinability model in composite materials. The Machinability Index for various composite materials with different thicknesses was found experimentally, which showed very different results for different materials. A study of the effect of the abrasive waterjet process parameters on the quality of cut (taper and surface roughness) was carried out.
