Experimental Investigation and Optimization of Wire Drawing Process Parameters
Gangurde S R, Pawar P J and Paraskar C B

Wire drawing is a metalworking process used to reduce the cross-section of a wire by pulling the wire through die. Steel, copper and aluminum are commonly used wire materials. Wire drawing has many important parameters like die angle, bearing length, coefficient of friction, percentage reduction, lubrication, surface roughness, tensile strength, etc. Die angle is the most affecting parameter on wire drawing. At higher die angle, percentage reduction increases with drawing load and friction and vice versa. Bearing length should be equal or higher than the wire radius to eliminate the elastic recovery effect. Also, type of lubricant affects the surface qualities of wire. In this paper, die angle, bearing length and lubrication are selected as input parameters, and energy consumption, speed of wire drawing and surface roughness of wire are selected as output parameters. The experiments are conducted on copper wire of 18 gauge (1.219 mm), which is reduced to 19 gauge (1.016 mm). The experimentations are performed by considering three levels of three input parameters. Taguchi method is used to optimize the process parameters of wire drawing. The optimal parameters are found as die angle 80 and bearing length 0.3 mm with oil as lubricant.

A Comparative CFD Analysis of the Flow and Heat Transfer Process of Engine Oil Containing TiO2 and CuO NANO-Additives Inside Steel Piston Cooling Gallery
Ankitkumar A Modi, Arvind S Sorathiya and Pravin P Rathod

This paper presents a comparative study on oil fill ratio and heat transfer coefficient within the steel piston cooling gallery for engine oil containing TiO2 and CuO nano-additives, respectively, by using Ansys fluent package. Both nano-additives of 50 nm diameter are added individually in engine oil in proportion of 1%, 2% and 3% for CFD analysis of oil flow and heat transfer process. The evaluation is carried out considering 2100 rpm engine speed. Also, the empirical value of heat transfer coefficient has been calculated.

Optimization of Pulsed TIG Welding Process Parameters on Mechanical Properties of AA 6061 Alloy Joints
Pratik T Kikani

The study pertains to the improvement of mechanical properties of aluminum alloy welds through pulsed Tungsten Inert Gas (TIG) welding process. The study aims at selecting optimum parameters on Pulsed TIG welding aluminum alloy 6061 butt joint. Input process parameters (peak current, base current and frequency) are varied, and tensile strength and hardness are determined. Full factorial method is employed to optimize the pulsed TIG welding process parameters of aluminum alloy welds for increasing the mechanical properties. Optimization of selected parameters is done by response optimizer. After optimization, the results are validated.

Implementation of Zero Defect Concept Through Quality Tools for Process Capability Improvement of Diesel Engine Pin
Rahul H Gandhi and G D Acharya

We live and work in a hyper competitive world. Competing and winning in today's global marketplace require products and services of high quality developed with short lead times with minimum waste and optimum use of resources. This requires very robust processes; for that, zero defect is a quality concept to survive in this market with continuous improvement in process. The paper presents a study of zero defect concepts through application of quality tools to improve process capability and obtain quality product. It takes advantages of Failure Mode Effective Analysis (FMEA), Statistical Process Control (SPC) and Measuring System Analysis (MSA) to adapt innovative technologies integrated with the operational aspects in order to prevent failure in diesel engine pin. The process validation is carried out through SPC to validate the process. The study concludes with the development of process improvement activities with reduction in non-conformities to achieve zero defect concepts.

Design and Development of Hydraulic Machine Vice
Shweta Desale, Gayatri Fegade, Meghana Kakade, Prajakta Bhosale and Priyanka Chavan

During machining, holding the component firmly is always a crucial task. Workpiece never has the same size, shape and material. It requires different forces and different sizes of clamping jaws. In an ordinary vice, the human power requirement is more to tighten the heavy jobs, but in the machine vice, the hydraulic arrangement is used to tighten the job automatically. In this paper, reduction of human effort and enhancing safety play a vital role while designing and fabricating the machine vice, which is used to hold the components during heavy machining works. In normal machine vice, the human labor involved in operating the handle to grip the component tightly is more. Excess amount of human effort generally results in damage to the workpiece. This may be avoided using hydraulic machine vice, in which the workpiece cannot be damaged while clamping the job, as only adequate amount of pressure is exerted to tighten the job. In this vice, we can also hold components of different shapes with the help of the adjustable jaws that can be provided if needed. A lever slides the movable jaw, using a lead screw for forward and reverse movement of the movable jaw. Hydraulic machine vice can be used for all types of machines.
