TAILIEUCHUNG - Tool wear rate optimization in PMEDM using titanium powder by Taguchi method for die steels

The objective of this paper is to optimization of input parameters for the TWR in PMEDM using powder titanium are presented. The Taguchi method was applied to the processing parameters to investigate the following: workpiece material, tool material, polarity, pulse-on time, current, pulse-off time, and powder concentration. | SCIENCE & TECHNOLOGY DEVELOPMENT, , - 2016 Tool wear rate optimization in PMEDM using titanium powder by Taguchi method for die steels Banh Tien Long 1 Nguyen Huu Phan 2 Ngo Cuong 2 1 2 Hanoi University of Science and Technology, Hanoi, Vietnam Technical-economics college, Thai Nguyen University, Vietnam (Manuscript Received on March 08th, 2016, Manuscript Revised May 04th, 2016) ABSTRACT Powder mixed electrical discharge maching method was applied to the processing parameters (PMEDM) is a complex machining process to investigate the following: workpiece material, which is controlled by a number of machining tool material, polarity, pulse-on time, current, parameters. Each machining parameter has its pulse-off time, and powder concentration. The own influence on performance of the process. For analysis used the Taguchi method and given the achieving the best performance of the electrical optimal value for TWR with respective discharge machining (EDM) process, it is crucial parameters. Electrode material affected the to carry out parametric design responses such as strongest factor, the Taguchi coefficient, S/N of Metal Removal Rate (MRR), Tool Wear Rate TWR. And the optimal value of TWR was (TWR) and Surface Roughness(SR). The mm3/min. Results from optimization calculations objective of this paper is to optimization of input and experimentation have demonstrated high parameters for the TWR in PMEDM using accuracy and efficiency. powder titanium are presented. The Taguchi Keywords: EDM, PMEDM, TWR, Taguchi method, S/N ratio. 1. INTRODUCTION Electric discharge machining (EDM) is one of the most popular machining methods to manufacture dies and press tools because of its capability to produce complicated shapes and machine very hard materials. But the low machining efficiency and poor surface quality are the major drawbacks of this process which Trang 88 restricts its use in mechanical manufacturing. To overcome these drawbacks and
