Geometric Dimensioning and Tolerancing (GD&T) system eliminates ambiguities in engineering drawings and brings out the designer's intent very clearly. It ensures seamless communication between design, engineering, manufacturing and quality teams across the entire organization enabling them to work in a concurrent engineering environment. In the competitive industrial scenario prevailing today, proper application of the GD&T system helps the companies to reduce manufacturing and inspection costs.

• Cover the philosophies of how, when, and where to apply geometric along with common sense tips for producing quality parts
• Provide a solid grounding in the fundamentals of geometric tolerancing based on the latest ASME Y14.5-2009 Standard
• Prepare participants for the ASME Geometric Dimensioning& Tolerancing Professional (GDTP-Technologist) Level examination
• LIVE DEMO- The sessions will be supported with a live demonstration of measurement of GD&T parameters using CNC Coordinate Measuring Machine (CMM) as well as conventional metrology equipment. Demonstrations will be delivered by Industry Experts from IMTMA Technology Centre.

The course is suited for beginners as well as experienced professionals with no prior OR minimal GD&T experience, who are looking to get in-depth knowledge and grip on best practices in GD&T and the ASMEY14.5M-2009 standard OR are aiming for ASME GDTP Technologist Certification.

At the end of this course, the participants will also attempt a mock test based on the ASME GDTP - "Body of Knowledge" Guide to prepare individuals for the ASME GDTP-Technologist certification exam. The Answer Key will also be provided to all participants after completion of the Mock test, for self-evaluation.

This program will be conducted by Mr M. Krishnamoorthy.
M. Krishnamoorthy is the Senior Director of IMTMA Technology Centre and an authorized training instructor with ASME, NY for delivering accredited ASME GD&T Trainings. He has undergone advanced training in GD&T from ASME in Seattle, USA. He is a certified ASME GDTP Senior Professional after successful completion of Senior Level GDTP certification examination by ASME, USA.

For over 30 years of his continued engineering practice in the industry, he has acquired astute expertise in the application and use of GD&T principles in CAD/CAM, high precision CNC machining as well as conducting Technical Training. He has imparted specialized training in GD&T for more than 800 engineers across manufacturing companies in India and assisted them in implementing GD&T in design through manufacturing. He is a postgraduate in Production Engineering from PSG College of Technology, Coimbatore. Prior to working at IMTMA, Mr Krishnamoorthy has worked at ISRO Satellite Centre, Bangalore in the field of Precision Machining of the satellite onboard components. After ISRO, he was with Perfect Moulds and UMS technologies as a specialist in Tool Planning and Production and Technical Training in CAD/CAM/CAE, respectively.

At IMTMA, his role is to develop and introduce new programs for enhancing the competitiveness of the industry.
