सवाल
Is non-conventional machining covered in detail?
Yes. EDM, ECM, USM, AJM, LBM, EBM and PAM are explained with principle, parameters, merits and uses.
Are indexing problems included?
Yes. Simple indexing calculations on the dividing head are practised.
Is this course based on the BTEUP syllabus?
Yes. The units follow the BTEUP (Board of Technical Education, Uttar Pradesh) diploma syllabus. If your polytechnic follows a different board or a revised scheme, the centre teaches your own syllabus.
