ORGANISATION EXPERIENCE:
1] I am working at Viraj Forging Ltd. MIDC, TARAPUR, (Thane, Maharashtra) since October 2006 as Senior Engineer in Design (Forge Shop). Viraj Forging Ltd (ISO 9001:2000) is now the third largest manufacturer of stainless steel Flange in the World. Company produces different type of Flange such as WNRF, WNRTJ, SORF, SORTJ, BLIND, STUBEND, DIN with different shape and size depending upon basic size of pipe and variable pressure up to 500g to 1.5 MT.

Designation : Senior Engineer, Design.
Duration : October 2006 to Till Date.
Scope :
- Analyze the cost of material and giving quotation to customer as per drawing and Material specification.
- Inspection of Drawing provided by customer or manufacture by other sources.
- Preparing the work instruction details as per drawing.
- Standardized suitable process for new product.
- Inspection of forging drawing of component and dies.
- Calculation of cut wt. of forging component.
- Selection of size of raw material.
- Handling Technical Feasibility of New Enquiries.
- Controlling and monitoring the process for development of new items.
- Planning Quality checks for the first sample lot.

2] AFTC-Metform Research, Bangalore (During M.Tech Project) :

It is a design consultancy based on Design of Forging and casting process. They solve industrial project by given proper design parameter and simulate through different software.

Designation : Trainee Engineer
Duration : July 2005 to June 2006
Scope :
- Design of forging component given different forging design parameter(allowance).
- Drafting (2D View) of forging component.
- Making model of forging component through Software.
- Die design and Drafting given different Design parameter.
- Drafting of dies.
- Making model of Dies through Software.
- Calculation of cut wt. of forging component.
- Selection of size of raw material.
- Simulate it through Simulation Software.
- Optimize it for better yield & Die life.
- Die stress Analysis.
- Die life calculation.

Platform : Unigraphics NX2, DEFORM(3D)5.1.

Achievement: Successful development of hanger Arm & Synchro Cone by changing design parameters and simulate it by many no of times we got better dielife and yield than others.

HANGER ARM
1. The yield obtained using the proposed practice is 62 % which is 7 % greater than the present yield of 55%.
2. The die stress is low in the proposed practice than in the present practice based on both simulation and empirical evaluation.
3. Die life increased by 28%. Previous it was around 2500 units. Now it is around 3200 units.

SYNCHRO CONE
1. The yield obtained using the proposed practice is 70% which is 7% greater than the present practice of 63%.
2. The die stress is low in the proposed practice than in the present practice based on both simulation and empirical evaluation. So the die damage should decrease and die life increase.

3] One month In-plant training in “Heavy Engineering Corporation” Ranchi, Jharkhand.

4] One month training in “Central Mechanical Engineering Research Institute” Durgapur (WB).

PROJECT PROFILE :
- M.Tech:
Title: “Optimization of Die Design and die life Improvement using ‘DEFORM’’

Place: Advanced forming technology centre, Bangalore

Objective: In the present scenario of competitive production, not only producing a good quality product, but making it within minimum cost with in a limited time. In case of closed die forging, the cost of dies equals to 10-15% of the overall cost of production. Further a study performed by Forging Industries Association estimated that 20-40% of the material is expended as flash, which indicates that the yield is low. This implies that considerable decrease in production cost can be achieved with the optimize die design and improvement of die life.
This can be approached by having a large body of experience with a given part and material by conducting experiments to determine the proper conditions through trail and error. It is time taken work as well as costly. In order to maintain and increase the present market for forging, it is necessary to go for computer simulation Software. “DEFORM” is such type of forging simulation software.
