Training Programme onBasic CNC Part Programming onTurning Centre & Machining Centre(VMC & HMC) for MVIT14 th -15 th and 27 th - 28 th February 2013UNIDO- ICAMTBangalore

IntroductionThe International Centre for the Advancement of Manufacturing Technology is anInternational Technology Centre of the United Nations Industrial Development Organization.ICAMT has been set up in cooperation with the Government of India for promotingmanufacturing technologies and innovations as a means to deliver industrial competitivenessin developing countries.CNC Technology, be it as a Product or a manufacturing practise, is an integral part ofmanufacturing technology across the spectrum of Industries, be it small, medium or large.The subject is also being taught at Graduate Course level in Engineering and is also aseparate focus area in Post-Graduation Degree courses. Although, the workshops at theColleges do have CNC Machines and equipments for Demonstrations, they do not have theexpertise to train their students to understand, operate and see CNC Machines working inthe shops. With a view to make the students to get first-hand experience of the use /application and to make them enthused to look at Manufacturing as a future career option,UNIDO – ICAMT has launched this unique initiative – Institution – Academician Interface forknowledge transfer / awareness creation of CNC Machining in shop environment.ObjectivesThe objective of the training course was to provide basic knowledge on CNC machining,tooling, cutting parameters, process planning, CNC part programming, machine setting, workholding and troubleshooting with emphasis on efficient metal cutting techniques and bestshop floor practices. More importance was given to efficient programming, problem solvingtechniques, tools and cutting parameters.Agenda for TurningDay 1: 14 th February 201309.30 am - 10.00 am Registration10.00 am - 10.30 am Knowledge inventory – Oral introduction10.30 am - 11.00 am Introduction Turning CentersMachining operations11.00 am - 11.15 am Break11.15 am - 01.30 Cutting tools and its applicationsCutting parameters & CalculationsG-codes & M-codes & Program format01.30 pm - 02.15 pm Break02.15 pm - 03.00 pm Programming concepts for General turning,Grooving, Threading and Drilling operations03.00 pm - 03.15 pm Break03.15 pm - 05.00 pm CAD CAM PracticeVenueUNIDOICAMT3

stageBangalore-58Training MethodBefore the training was conducted a comprehensive approach was undertaken tounderstand specific requirements of Engineering College-MVIT. The National Consultant, MrNingappa collected data about their requirements and prepared the course material toconduct the 2 days+2days training program on CNC Turning & Machining center (VMC &HMC).The training included classroom lecture sessions, simulation and learning through the CADCAM software. Participants also had the opportunity to incorporate their learnings throughactual hands-on working on the CNC Turning & Milling machines at M/s Jnanavi Precisionand SLN Precision Works. The classroom lectures were supported by multimediapresentation and interactions with frequent question and answer sessions. Sessions onmachining strategy were taught by using the CAD (Computer Aided Design) CAM (ComputerAided Manufacturing) software which was followed by group exercises and problem solvingto ensure their understanding. For the hands on session the participants were taken to theM/s Jnanavi Precision and SLN Precision Works. They got to work on actual machines.Summary of ProceedingsTwo day+ two day Training on CNC Part Program on Turning & Machining centers for 22+22students from the MVIT college of Bangalore was conducted at UNIDO International Centrefor Advancement of Manufacturing Technology (ICAMT), Bangalore on 14-15 and 27-28 Feb2013 (9.30am to 5.00pm).5
