Questions
Is programming practice included?
Yes. Programs for typical turning and milling parts are written in class; actual machining is done in the CNC Lab.
Which controller is used for codes?
Fanuc-style ISO G and M codes are taught, as used in most Indian industries and the syllabus.
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.
