WORK EXPERIENCE

Product Design Engineer Intern at Pinak Industries, Mumbai, India (June 2017 - Sep 2017)

Led design of new valves, gearboxes(CREO), industrial sprockets per customer requirements to meet ASME-IS standards.

Managed pre-design discovery,3D modeling, prototype build, mold construction, quality and test plans, and order fulfilment.

Identified project cost estimates and calculated additional budgetary necessities for new product line production.

Implemented kaizen to standardize the gearbox and valves sizing process for improved accuracy. Managing machine shop.

Practical experience of operation in Gear Hobbing machines, Milling machines and Lathe machines. Ensured designs met industry codes, standards and accepted engineering practices. Created technical documents including parts lists and BOM.

Design Engineer at Top Gear Transmission Pvt Ltd, Satara, India (July 2015 - May 2016)

Generated CAD and assembly drawings of Milling fixtures for machining of carrier using AutoCAD & SolidWorks.

Performed root cause analysis to detect faults in design and manufacturing processes. Value engineering and weight reduction in AGB casing design. Testing rig for testing AGB gear boxes, assessed manufacturability of completed design.

Analyzed the inputs with engineering calculations and statistically get the appropriate values suitable for process using SPC and process capability. Variability in parameters were determined by Fishbone diagram and scatter plot using Minitab.

Knowledge of manufacturing methodologies (forging, casting) of large components. Prepare Engineering Change requests.

Manufacturing & Quality Intern at Metalok Industries Ltd, Mumbai, India (Feb 2013 - Nov 2013)

Designing and drafting using SolidWorks (high pressure needle valves, Instrumentation, Fittings and air manifolds).

Eliminated wastes and reduced variability in the manufacturing process using Lean, 5S, Kaizen and six sigma methods.

Performed and documented visual and dimensional inspection of incoming and finished components of Valves as per TQM.

Liaison between the Sr Manufacturing Engineer and Sr Quality Engineer. Configured NCR reports, data entry &check sheets

Demonstrated advanced skills in operating equipment and CNC (HAAS ST-15, HAAS ST-20), generated codes for CNC.

PROJECTS

The Cart Project

Designed a CART model using PTC Creo and SolidWorks, modelled the various parts such as cargo, frame, wheels, hex bolts, handle (71 parts) and assembled them. Checked for global interference and resolved it after assembly.

Created detailed drawings of the total assembly, sub-assembly and few of the main parts of the cart.

Paper Shredder Redesign

Redesign the paper shredder (eliminating parts not value adding) using CATIA and AutoCAD, the new design had increased manufacturability, greater design efficiency and less material usage.

Calculated the design efficiency and unit production cost using Boothroyd Dewhurst method and PRO DFM software respectively. The unit production cost of the redesigned paper shredder was 60% of the original cost.

Steady State and Transient Thermal Analysis of DSP Chip

Created different parts of single DSP chip such as silicon, chip, under-fill, substrate, coating using CREO.

Performed steady state and thermal analysis to determine locations of Von-Mises stress and maximum strain.

Manufacturing of industrial ball valves

The manufactured industrial ball valve was tested for failure by applying loads at various points using ANSYS software. Failure mode and effect analysis(FMEA) were applied to improvise the product. Studied variation of flow parameters.

Arbor Press

SolidWorks project for designing Arbor Press and manufacturing its parts in CREO & checking for Interference.
