"Design of Fixture – Specialization"
(Machining / Welding / Assembly and Inspection Fixtures)

A six-day course on 'Design of Fixture - Specialization' was conducted as an introduction to Fixture Design basics to final design was from May 16-21 at Pune. Design of fixture is a key effective utilization of machine tools. Basics of fixture design if not implemented correctly results in poor productivity and quality problems. Set-up time and cycle time reduction, increased accuracy on components, deskilling the job setting operation are the obvious advantages of a good fixture. Competence in right fixture differentiates excellent organizations.

Geometric Dimensioning and Tolerancing (GD&T) Certification by ASME

Geometric Dimensioning and Tolerancing (GD&T) Certification by ASME


Geometric Dimensioning and Tolerancing (GD&T) defines a set of symbols and rules to mention the dimensions and tolerances in a engineering drawing.


Why GD&T ?

No doubt, ultimate aim of any design is that, it should be manufactured in minimum cost and of course with optimum quality standards. GD&T enables Design team to critically review the design based on functional requirements and assembly considerations. Thus the design intent is brought forward with utmost clarity and conveyed all across the organisation. Team members from other functions including Engineering, Production, Quality, Assembly, etc.,interpret the drawing in the same manner with out any difference of opinion.

Advantages of GD&T ?

Reduction of manufacturing cost and lead time can be realised by proper application of GD&T. In the Globalised Manufacturing environment prevailing today, GD&T ensures seamless communication across industries, customers vs suppliers, etc.., enabling universal interchangeability.

ASME-GDTP Certification

The American Society of Mechanical Engineers (ASME) in recognition of the needs and benefits associated with standard qualifications for professionals using geometrical dimensioning and tolerancing and the ASME Y 14.5M standard established the Geometric Dimensioning and Tolerancing Professional (GDTP) certification programme. The programme provides the means to recognize proficiency in the understanding and application of the geometric dimensioning and tolerancing principles expressed in Y14.5.

There are two levels of certification. The first level, Technologist GDTP provides a measure of an individual's ability to understand drawings that have been prepared using the language of geometric dimensioning and tolerancing as defined in the Y14.5 Standard. The second level, Senior GDTP provides the additional objective measure of an individual's ability to select and apply geometric controls to drawings.

Indian Machine Tool Manufacturers' Association (IMTMA), as an authorized training provider of ASME has trained around 125 industry professionals since 2013 in GD&T preparatory courses for ASME GDTP certification. The training programme focuses on understanding the system of GD&T and the methods of applying it in real time design by using case studies, examples and exercises. The programme covers the philosophies of how, when and where to apply geometrics for producing quality parts. Unique hands-on sessions in measurement lab to practice with the application of GD&T rules using the functional gauges, conventional as well as state-of-the-art measuring systems such as CMM on various engineering parts and components are a part of the programme. On behalf of IMTMA, Mr. M. Krishnamoorthy, Director of IMTMA Technology Centre and an authorized training instructor with ASME imparts training for industry professionals. Mr. Krishnamoorthy had recently undergone training on Advanced Concepts in GD&T from ASME at Seattle, USA.

Cost reduction and Quality enhancement through VA / VE

Cost reduction and Quality enhancement through VA / VE

The value analysis/ value engineering is the foundation for success for any new product/ process being developed. It is also a useful tool to deal with post product release problems and process improvement innovations. The value engineering is used to create functional breakthroughs by targeting value mismatches during product, process and project design. In today's competitive world the organization need to become faster, better and cheaper to survive. The VA/VE helps the organization to place their product in the market with an edge against the competition. The value analysis approaches and techniques will help the persons involved to obtain a better answer to their problems that determine costs and quality, in competitive business. This difference can change the organization from being "Good" to being the "Winner".



Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) had organized a 2 day programme on Cost reduction and Quality enhancement through VA / VE on 3 and 4 May 2016 at IMTMA Technology Centre in Pune.



The training programme focused on :

  • Understanding concepts and approaches of value engineering and analysis
  • Use of Kano's model to determine customer perceptions
  • Types of value analysis and case studies
  • Value map and value creation
  • How to use value analysis
  • Orientation phase
  • Function analysis
  • Creative phase
  • Evaluation phase
  • Implementation
  • Cost reduction and quality enhancement
  • VE/ VA Exercises



The programme was conducted by Mr. Krishna Raghavendra Bhat, former Vice President - Manufacturing at L. G. Balakrishnan & Bros., Coimbatore. Mr. Bhat has over 35 years of experience in manufacturing engineering and plant operations. Delegates from NRB Bearings Ltd, Tata Steel Processing and Distribution, Tata Motors, Steer Engineering, Shalaka Shafts, Rotex Automation, Schrader Duncan, and Valeo India attended the training programme.

Robust Product and Process through Design of Experiments and Taguchi Approaches

Robust Product and Process through Design of Experiments and Taguchi Approaches

Product Quality issues either resulting from design or from manufacturing process or from service etc., not only results in repair and re-work but also leads to erosion of profit by way of re-calls, replacements, etc. However, significant damage is caused to credibility and reputation of the company, resulting in competitive edge and loss of business in global economy. It is absolutely essential to understand the root cause of issues and address the variations by in-sensitizing them, either in Design of New Products or in fixing field issues of existing products or even enhancing the productivity in a manufacturing environment, product quality and cost reduction.


Robust engineering is one of the popular approaches that industry leaders follow in eliminating or containing the product quality issues and consequent erosion of profit and losses. It aims at addressing variations and in-sensitizing the noises. Robust design approach was promoted and popularized by Taguchi. This approach is different from Design of Experiments through Factorial Designs and addresses quality issues by recognizing noise as external environment which are not controllable but has an influence in product quality and consequent loss of business.

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) organized a 2 day programme on Robust Product and Process through Design of Experiments and Taguchi Approaches on 19 - 20 April 2016 at IMTMA Technology Centre in Pune. The programme focused on providing an overview of various approaches like factorial, fractional factorial DoE, DoE in Taguchi Method, benefits of applying and practical applications in designing a robust product / process.



The training programme focused on:

  • Overview and recapture of Effect of Variation, Statistics for Engineers and Anova
  • Experimental Designs, Factors, Responses & Interactions
  • Recognise Inputs, Process, Output Response, Control Factors and Noise Factors in Engineering
  • Design of Experiments Full Factorial & Fractional Factorial Designs
  • Overview of Taguchi’s approach to Robust Design
  • Understanding of Elements, Terminology, benefits and plan related to Robust Engineering
  • Taguchi's DoE Structure - Orthogonal Design with Inner and Outer arrays
  • Signal to Noise Ratio & Quality Loss Function
  • Hands-on exercises using Minitab


This programme was conducted by Prof. L Ramanan, an IITM alumnus and Founder CEO of RAISE Consultancy Services and visiting faculty in many prestigious institutions of repute.

Delegates from Meccanotecnica India, ELGi Ultra Industries, Setco Automotive, Defence Research & Development Organization, and Fiat India Automobiles, attended the training programme.
