Plunge milling is a recent and efficient production mean for machining deep workpieces, notably in aeronautics. This paper focuses on the minimization of the machining time by optimizing the values of the cutting parameters. Currently, neither Computer-Aided Manufacturing (CAM) software nor standard approaches take into account the tool path geometry and the control laws driving the tool displa...

-The Aluminum Hybrid Metal Matrix Composites (Al-HMMC) are finding numerous applications in many areas like Automobile, Piston and Cylinder and Aerospace, etc. Adding a third element into the metal matrix composite makes it hybrid. The Reinforcement of SiC and Graphite used in this Al-HMMC improves its strength. The present investigation is to find the optimum machining parameter of CNC turning...

High-speed steel (HSS) tools are the most commonly used tools in small and medium-scale industry. Cryogenic treatment can be used to enhance the tool life. Studies on cryogenically treated (CT) cutting tools show micro structural changes in the material that can influence the life of the tools significantly. This paper primarily reports performance of CT HSS tools as compared to untreated (UT) ...

This paper presents the performance evaluation of three different cutting fluids used in a minimal quantity lubrication (MQL) system. The MQL system, developed in-house at the University of Malaya, was capable of delivering high velocity cutting fluid in narrow pulsed jet forms at a rate of 2 ml/min and a pressure of 20 MPa. The three cutting fluids chosen were neat oil, soluble oil and semi-sy...

A recently developed topological mesh modeling approach allows users to change topology of orientable 2-manifold meshes and to create unusual faces. Handle-faces are one of such faces that are commonly created during topology changes. This paper shows that vertex insertion and corner cutting subdivision schemes can effectively be used to reconstruct handle-faces. These reconstructions effective...

This research work describes an intelligent and modular architecture for controlling the milling process. For this purpose, it is taking into account the admissible input cutting parameters given by the stability lobes and restrictions of the system, calculating the quasi-optimal cutting parameters. The quasi-optimal cutting parameters are obtained considering a cost function with multi-objecti...

This paper discusses the selection of tools and cutting parameters in milling operations. To carry out this research, an expert system has been developed based on numerical methods of performance evaluation. The knowledge base is given by limitations in process variables, which let us to define the allowable cutting parameter space. The mentioned limitations are instabilities due to tool-work-p...

This study investigated the optimization of End milling of AISI 1018mild steel by various lubricants using the Grey relational analysis method. Quaker 7101, Blasocut strong 4000 and Velvex have been selected as lubricant. All the experiment are carried out at different cutting parameter (Number of Tool Flutes, Depth of cut, Spindle speed and Feed rate) in various lubricant assisted environment....

Fabricating machine parts and components with low cost, less time, and high quality is the major objective in the metal cutting industry. Machining parameter optimization plays an important role in achieving this goal. It is an essential part in digital manufacturing with little or no involvement from humans. In this paper, the parameter optimization problem for face-milling operations is studi...
