Questions

Will I run programs on a real machine?

Yes. After simulation, each program is run on the CNC trainer lathe / mill under supervision.

Which control system is used?

Fanuc-style ISO codes; other controllers available at the centre are also shown.

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.
