Summary of the Project: Deep holes are required to be precision machined for aerospace industries, weaponry, automotive and textile. As the ratio of depth to diameter increases, it becomes; extremly dificult to produce such holes. The improvement of machining accuracy of machining (ECM) continues to be a major challenge for fabrication of aerospace components.This project proposes to improve surface finish of electrochemically drilled deep hole using rotating electrode. There is a substantial gain in machining accuracy and quality of surface by ECM.
Outcome Results: n house design and development of rotating tool arrangement with ultrasonic vibration in ECM. For rotating tool with ultrasonic vibrations, minimum Ra value is 0.172 µm. at voltage 12 V, tool feed rate 1.0 mm/ min, pulse on-time 500 , duty cycle 0.64,tool rotation 65rpm, Ultrasonic Vibration 20Kz, and pressure 1.4kg/cm2 constant. The other corresponding responses are MRRg= 0.019gm/min,ROC=0.287mmand Js=9.074 A/cm2. And rotating tool showed that the minimum surface roughness, Ra=0.6 µm. (Enhanced Surface finish (Ra) = 70%, i.e.0.6 to 0.172 µm)

Summary of the Project: The Electrochemical Machining (ECM) is widely used in machining variety of components used in aerospace, automotive, defense, and medical applications. Due to low machining accuracy ECM is yet to be a best alternative process. ECM with pulse current offers an enhanced accuracy control. This paper presents experimental investigation of PECM parameters such as Voltage, Pulse on time and duty cycle on surface enhancement by PECM arrangement. This results shows PECM with stationary tool has enhanced surface by 44 % as compared to DC-ECM stationary tool (2.11 to 1.18 micron). The design of experiments was done by 2k factorial designs. The experimental results were analyzed by analysis of variance (ANOVA) method and by plotting various graphs.
