ARPAC manufactures packaging machinery (wrapping, palletizing, shrink bundling) for different industrial needs. Software's used: Creo 2.0 (Design & Drafting); AutoCAD (Layouts/Pneumatics); Vantage (PDM); CADlink (ERP/purchasing) Project: Designing a linear conveyor machine capable of filling, shrink wrapping & palletizing. Special care is being taken in choosing the materials as it involves edible food. • Design of components for shrinking a packaging machinery as per the customer requirements. • Researching for the electrical & mechanical parts(motors, actuator, hydraulic cylinders) from other manufacturers. • Analyzing the design for the thermal and the static stresses. • Building of BOM's for purchasing, working with machinists regarding the drawings.

ATS Automation provides factory automation solutions for the world's leading manufacturers. Software's used: Solidworks'16 (Design & Drafting); AutoCAD (Layouts/Pneumatics); PLM Works( PLM); CADlink (ERP/purchasing) Insulin Pen Machine: Designed a rotatory assembly machine with 12 sub-stations to assembly insulin pens 7 stack them containers. Syringe Assembly Machine: Designed a machine which fills the formula in the syringes & assemble with 3 parts. • Designing parts, assemblies following DFM/DFA for costume automated equipment using SOLIDWORKS& factory layouts using AUTOCAD • Updating the design library: CAD models of purchased mechanical/ electrical parts in PLM Works • Drafting detailed part & assembly drawings including GD&T and BOM’s for ordering/ requisition to parts on the production floor. • Communicating with external companies for ordering parts & equipment • Providing Mechanical engineering support for builder/machinists working on the manufacturing floor

Lead designer at American Society of Mechanical Engineers (ASME) & Society of Automobile Engineers (SAE-USF Racing). Implementing data-driven approach for development & design validation. Analyzed data to provide design feedback & suggestions. • Designed surface body, wheels, brakes & transmission for a human powered vehicle using SOLIDWORKS. • Analyzed for stresses, calculated safety factor, performed simulations, researched alternative materials, optimized design, decreased weight (12%) & increased the performance & speed using Ansys/ SOLIDWORKS. • Used 3D printing and CNC machining to create prototypes; performed testing and validation to identify issues. • Organized seminars, guest talks & technical events. Presented technical papers & poster presentations.

Mechanical engineering responsible for design, manufacturing & quality assurance of submersible pumps. Planed, scheduled and managed complex phases of the engineering projects through completion, increasing the overall production time by 5%. • Drafted production drawings of parts & assemblies with detailed annotations (GD&T, Tables, machining symbols, BOM’s) using AutoCAD. • Designed & verified parts, components, assemblies, tools, plastic injection molds, conveyer belts, jig & fixtures in SOLIDWORKS. • Efficiently designed products in accordance with DFM & DFA to support cost effective production. • Supervised assembly line machines, manufacturing team with the technical design & manufacturing issues. • Prototyped, integrated, assembled, tested and released into production a new and improved product. • Upgraded statistical methods, tools and techniques for monitoring production/processes & Inspected products for Quality & Tolerance. • Prepared reports by collecting, analysing and summarizing data, made recommendations. Worked with vendors & customer.

CAD/CAE engineer provided engineering services for aerospace, automotive, industrial machinery, electro mechanical & engineering sectors. • Created 3D-models, mechanical components, assembly documentation using Unigraphics NX & Pro-E as per client’s requirements. • Performed hand calculations & FEA analysis of components as it relates to thermal, static loads, vibrations etc. using HyperMesh. • Built technical documentations (exploded views, animations), executed design verification, interference & motion analysis, tolerance stack-up • Implemented automation tools, managed design library in SolidWorks that dramatically improved shop-drawing production
