EXPERIENCE:

Manufacturing Engineer: (May 2011 to Jan 2013) Perfect Boring Works, India.

Refined Supply chain and manufacturing operations by implementing lean principles: 5S, Value Stream Mapping (VSM), Kanban, Poka-Yoke.

Assisted with Equipment Demand forecasting and followed-up with suppliers to ensure timely submission of machined products, thereby developing cost study for change request from customers.

Emphasis on modeling parts, assemblies, - preparing drawing for manufacturing with BOM, Piping and Instrument Diagrams (P&ID’s) and 3d models for FEA Analysis and presentation works.

Applied Six Sigma techniques and quality control procedures to manufacturing processes and supported industrial engineers with time studies to reduce cost of the manufacturing processes.

Working consistently with the designing team, in development of parts using solidworks and dimensioning as per the GD&T applying ANSI 14.5 Standards.

Worked on Continuous Improvement (CI) project and supported Lean manufacturing and 5S initiatives.

Support issue resolution for production and assembly including root cause investigation and corrective action tracking.

Review Material requirements planning (MRP) to create cost effective inventory, time delivery and maintain warehouse lean performance.

Providing training and coaching in use of continuous improvement methods such APQP and tools to production associates, leading to a culture of engagement and accountability.

Defined yield and quality improvement goals and consulted with 21 suppliers.

Providing information and knowledge towards successful ISO 9001:2008 certification.

Quality Engineer: (Feb 2013 to June 2014) Polymax, GIDC, Vadodara, India.

Consistently monitored return product history and sought continuous improvements through root cause analysis, design of experiments (DOE), and supplier quality management.

Selected the Machine for particular component with Tool up proposal and fixture to reduce product cost, process cycle time and improve product quality assuring with GMP.

Modeling of Design parts in Solidworks and making necessary changes according to the ANSI 14.5 Standards.

Verification of materials used to construct product, inspection of product at each stage of assembly to ensure compliance with customer's specifications and drawings as well as company standards and practices, maintained documentation of acceptance, rejection, and corrective actions taken by production lot during product assembly.

Design and document machined parts and assemblies primarily for use in manufacturing and inspection support of custom products for industrial cooling packages.

Creating macros in Microsoft Excel for the similar part manufacturing as per the need. Also estimating cost in Solidworks PLM of the BOM and then importing it to excel for its modification.

Conducted delay studies to find top bottlenecks of delays, documented standardized work and best practices that improved cycle time by 10-15% and practiced line balancing to achieve takt time.

SIX SIGMA PROJECTS:

Improving Quality in Injection Molding Machine and preventing breakdown of Tie-Bar.

Developed Injection Machine model using CATIA V5 with the actual data from the Perfect Boring works Industry and analyzed the critical failure points causing vibration on Tie-bar at extreme loads. The analysis of the model was created in Ansys with varying conditions of temperature and loads. The end result of all the different condition was same i.e concentrated load on thread portion of Tie-Bar and the failure was instantaneous during the operation of injection molding machine.

For improvement, the model was modified from the existing design in PRO-E/ Creo(now), so as to reduce the stress concentration on the Tie-Bar and the new design was worked out with the company engineers and was tested successfully. The stress concentration found was very much less below the critical failure point on the Injection Molding Machine after the re-design, which prevented sudden breakdown of Injection Molding Machine.

Considering various factors such as idle machine time and repairing cost the company saved an estimated 2.3 Million from the improved design.

Root Cause Analysis of Defects found in Piston of Bosch.

The project was themed on Enterprise Excellence Method developed at UTA.

Analysis of Piston was done using Checklist and Pareto Chart, major Quality issues affecting the piston was identified from fishbone diagram and brainstorming.

Checklist was made to collect the issues in the quality. Why-why technique was used to identify possible causes. Finally root cause analysis was conducted and it was found that defect was produced before packaging and after anodizing. It was however noted that this defect was easily identified because of the Flow Chart Diagram.

The control Charts were made after correcting the defect and then the result showed almost zero defects in the run chart. Thus the quality of the piston was then improved and FMECA chart was then developed indicating the corrective action.
