Achievements
DEVELOPMENT OF PARAMETRIC C.N.C PROGRAMMING TEMPLATES FOR PISTONS: Achieved 50% reduction in programming time by developing expressions based parametric CNC program templates in Unigraphics NX6 for various piston configurations.
DEVELOPMENT AND OPTIMIZATION OF MANUFACTURING PROCESS FOR STEEL PISTONS: Achieved overall 50% reduction in manufacturing time and cost. Organized and lead a team of 4 people (machine operators, tool supplier, and materials engineer) to understand and eliminate component rejections, heat treatment process, manual machining as well as machining in multiple CNC machines and additional polishing.
DEVELOPMENT AND OPTIMIZATION OF MACHINING PROCESS ON NEW MACHINE: Achieved overall 25% increase in production compared to similar capacity machines in shop. Organized and worked with a team of 5 people (programming supervisor, machine operators, shop supervisor) to study the machine capabilities, tooling requirement and employ modern practices to develop safe and optimized machining process.
OFF-SHORING NC PROGRAMMING WORK: Saved $.30Million to client and met the client’s production schedule by successfully off-loading over 8000 Hrs. of NC programming work to overseas. Developed and lead a team of 2 people by empowering, teaching and mentoring extensively on Unigraphics NX-6, compressor parts and machining processes for different CNC machines.
Responsibilities
CNC PROGRAMMING SUPPORT IN UNIGRAPHICS NX-6:
Developed CNC programs for Vertical Turning Lathes from Toshiba(Fanuc control), Sundstrand(fagor control), Giddings & Lewis(Numeripath 8000) and Horizontal lathes with live tooling from Okuma(Okuma OSP control).
Developed CNC programs for multi axis Machining Centers from Toshiba(Tosnuc control), Giddings & Lewis(Numeripath 8000), Nigata(Fanuc control), Ingersoll(Fanuc control) and Okuma(okuma OSP controls).
Worked for conversion and optimization of existing legacy as well as Unigraphics CNC programs by applying modern machining practices and advanced machining features of Unigraphics NX6.
MANUFACTURING METHODS IN ORACLE ERP:
Developed route sheets for compressor components by precisely analyzing time studies to reduce waste and rework.
Base lined the current manufacturing methods by thoroughly analyzing design intent, different stages in process and identified the gaps. Worked with shop personnel and shop supervisors in implementing detailed step by step manufacturing methods, ensuring engineering compliance in end product.
Collaborated effectively with product data group and design engineering team for issues regarding Bill of material,
item structure, drawing and manufacturing issues.
OPERATIONAL SUPPORT:
Bestowed the shop floor manufacturing support by collaborating with shop supervisors, machine operators, planners and suppliers in resolving manufacturing and tooling issues, program prove-out on CNC machine, as well as suggest/ propose supplementary equipment, process and fixture development.
Documented best practices and CNC programming process for different CNC machines for future reference and developed quality checklists to plug potential programming errors.
Lead and collaborated overseas teams by resolving issues related to drawings, process & CNC programming in
ensuring on-time delivery to meet production schedules.
Taught and mentored Unigraphics NX6 to client engineers and teams at overseas.
MODELING AND DRAFTING IN UNIGRAPHICS NX-6:
Created 3D manufacturing models and drawings for most of reciprocation compressor components as and when required to meet production requirements.
Major reciprocating compressor components for which CNC programs developed and route sheets created are cylinder, frames, piston and piston pins, cross-head, cylinder heads, distance piece, extensions, valve covers and cages.
