Design of Gauges
Design of Gauges
7 – 8 January 2015, IMTMA Technology Centre, Bangalore
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 inter-changeability 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 trouble free 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.
Keeping this in view, the Indian Machine Tool Manufacturers’ Association (IMTMA) organized a two day workshop on “Design of Gauges” on 7 and 8 January 2015 at IMTMA Technology Centre, Bangalore. The programme provided 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 workshop gave delegates an overview of attributable gauging system, types of ‘Gauges’, and ‘Gauge’ design criteria. It also gave them the 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, etc.
The workshop was conducted by industry experts from Nettur Technical Training Foundation, Bangalore.
Seventeen delegates attended the workshop. The delegates were from companies such as Ace Manufacturing Systems, Bosch, Defence Research & Development Laboratory, Esterline Connection Technologies, Guru Engineering, Indo-US MIM Tec., L&T, Otto Bilz (India), Schneider Electric India, and Wabco India.
