Design of Gauges
When a part is manufactured, it must be measured to ascertain that it is of the right dimensions for fulfilling the purpose for which it is intended. Gauges are one of the commonly used inspection tools in production shops for quick checking and validation of the dimensions of manufactured parts. Thus, gauging has become an integral part of any machining process and gauges help in ensuring required degree of interchangeability among the millions of parts manufactured worldwide. The type and the design of gauges depend on the application, volume of production and precision levels required.
In addition to simple plug and ring gauges, functional gauges or receiver gauges are being used to check location of different features with respect to the datum reference frame, as required. Functional gauges are a very effective way to gauge products during or after manufacturing and they ensure smooth assembly and operation. In all the cases, design of gauges is of prime importance because, if the gauge is designed incorrectly, it will be built, but never get used. The prime considerations for gauge design include part tolerances, gauge material, simplicity of use, manufacturability, etc.
Indian Machine Tool Manufacturers' Association (IMTMA) organized a 2 day seminar on Design of Gauges on 9 and 10 June 2016 at IMTMA Technology Centre in Bangalore. The programme provided delegates an in depth understanding of the types of gauges, principles of gauge design, design of plug and ring gauges, design of functional gauges, selection of materials and manufacturing of gauges.
The seminar primarily focused on providing participants about an :
- Overview of attribute gauging system
- Types of gauges
- Gauge design Criteria - Taylor's principle; Gauge maker's tolerances
- Guidelines for fixing tolerances for design of gauges
- Selection of gauge materials
- Design of limit plug and gap gauges
- Design of functional gauges for checking the positional tolerances with M modifier
- Design of gauges to check angular features
- Introduction to design of thread gauges and gauge calibration
- Exercises in design of different types of gauges
The seminar was conducted by industry experts from Nettur Technical Training Foundation, Bangalore. Delegates from Abi Showatech India, Bonfiglioli Transmissions, Brakes India, Forbes Marshall, Honda Motorcycle & Scooter India, Kennametal India, Streparava India, Wabco India, Weg Industries India, and Wipro Infrastructure Engineering attended the seminar.
Finishing School in Production Engineering
6 June - 2 July, Pune
Indian Machine Tool Manufacturers' Association (IMTMA) organized the 2nd batch of the "Finishing School in Production Engineering" from 6 June to 2 July 2016 at IMTMA Technology Centre in Pune.
IMTMA's "Finishing School in Production Engineering" focused on all the practical aspects of modern machining - from reading an engineering drawing through measurements and quality control
- including machining processes, CNC programming and operation, process planning, tool materials, selection of cutting tools and optimizing machining parameters, limits, fits and tolerances, GD & T and selection of measuring instruments. In addition to the technical inputs, emphasis was given to develop soft skills as necessary for manufacturing industries.
The course was conducted by industry experts from IMTMA Technology Centre, Sandvik Asia, Esprit, and Master Fluids. Industry visit to PMT Machines Ltd. in Pune was organized for the participants to get ‘live’ experience of the actual production environment.
The workshop was attended by 11 delegates. Six delegates were fresh engineers. Rest of the delegates were final year Mechanical engineering students.

Design of Spindle - Specialization
A six - day course on 'Design of Spindle - Specialization' was conducted in Gurgaon from June 20 - 25. It was structured considering Machine tool spindle as the most sophisticated member in machine tool and which plays a vital role for better performance, higher efficiency and accuracy. Design of spindle being a very important and a critical activity of machine tool design process.
The program started with an introduction to the spindle by Mr. H V Rajashekara, Sr. Director - Design Institute, with over 27 years of experience at HMT and Johnson Electric. Topics delivered by him were Introduction to CNC Machine Tool Spindles, Spindle Specification & Design Calculation, 2D Conceptual Spindle Layout, and Sketching of Assembly & Parts.
On the third day participants were trained in SOLIDWORKS by Mr. Rahul Vylen, on modules like part modelling and assembly and the on the fourth day, delegates developed a real time spindle for a particular application. Topics on Spindle stiffness calculation and bearing life calculation were also discussed on first principle basis.
On the fifth day, Mr. G Baskhar, carried the project further in terms of pulley and key design along with calculations. On the final day Mr. M A Khallaq, Managing partner M/s XL CNC and an ex-HMT as a Dy general Manager, severed the R & D dept, discussed Design of Boring and Grinding Spindles.
