IMTMA Training Centre

Hands-on training in Co-ordinate Measuring Machines (CMMs)

Date : 17 to 21 December, 2018

@ BIEC, 10th Mile, Tumkur Road, Madavara Post, Bangalore


In the modern manufacturing environment, process control and quality assurance depend increasingly on the performance of Co-ordinate measuring machines. Today CMMs have replaced traditional methods of inspection with gages and fixtures thus reducing the time and manpower required in quality control operations. However, thorough understanding of concepts, measuring uncertainty, GD&T, right probing method are very crucial for getting reliable results from any CMM.

Rapid growth of CMM population all over India has subsequently generated enormous demand of Trained / Skilled engineers for successful & meaningful handling inspection challenges. This can be achieved only if the CMM engineer possesses basic engineering knowledge, Inspection skills and has a logical and analytical approach to fulfill the task.

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) is organizing a comprehensive course with Hands-on training in Co-ordinate Measuring Machines (CMMs) on 17 - 21 October 2018 at Bangalore. This course will cover in detail about all the aspects a practicing CMM engineer requires to know for effective use of CMM for reliable measurement results. Hands-on training in CMM with live measurement exercises of industry components will be given more emphasis.

Participant Profile

This course will benefit Managers, Engineers & Supervisory personnel responsible for obtaining the best output from Co-ordinate Measuring Machines. Practicing engineers in quality and production functions from Machine Tool, Automobile, Tool room, General engineering and other capital goods manufacturing industries will immensely benefit from the contents. It will be specifically useful for Existing CMM engineers who may have faced significant problems in day to day applications And also for New CMM engineers who may have lot of doubts / grey areas on CMM applications and right ways of using CMM.

Pre-requisite: Participants should have basic operational knowledge of Co-ordinate Measuring Machines and be able to read engineering drawings.


This course will be conducted by Industry experts from IMTMA Technology Centre and Hexagon Metrology India.

The course will be practical oriented and highly interactive where participants can clear their doubts with regard to correct measurement procedure for specific components from their industry.

Participants Feedback

The programme has been managed very professionally and participant’s requirements has been taken care. Very happy to be part of the training programme. - Mr. R. Rajendra, Associate Professor, Osmania University Hyderabad

The training programme is very helpful to me. I have now improved more in GD&T concept. The CMM theory with practical also more helpful for next process of operating onwards in our company.
