Development of Mobile Application in Android, iOS and Windows for Evaluation of Optimal Machining Parameters in WEDM

Wire-EDM is a highly complex machining process, which is characterized by non-linear behavior. Owing to unique capabilities of machining complex shapes and hard materials with high accuracy and fine surface finish, WEDM is used in various manufacturing industries. There has been on-going research to develop automated capabilities for WEDM by understanding the interaction mechanism of various input parameters to get the requisite output measures like MRR, Surface Finish etc. To get the desired output measures, WEDM depends mainly on the operator’s experience and trial and error methods. To overcome this, a standard method for predicting output measures/parameters based on the input parameters in WEDM is yet to be developed, which is a key requirement for development of Mobile Application in Android for WEDM. In terms of the smartphone operating system (OS) market Android, Apple, Windows, Blackberry, others have a share of 86.2%, 12.9%, 0.6%, 0.1%, 0.2% respectively. So we chose Android, IOS and Windows as OS for the development of mobile application as they had a big market. In this app, to get the optimal parameters by selecting the material and thickness of workpiece to be machined for the desired parameters like Discharge current, Cutting speed, Spark gap, Material removal rate, Power, and Surface roughness. This application was tested and validated with the Experimental data and additional data in different tool rooms. It is observed that the application results in with the desired accuracy. This application can directly be used in any Android smartphones and tablets. It is a very user-friendly application that would save time, process planning, and also cost.
