Syllabus of lectures:

NC and CNC systems, basic features and abilities.

NC programming, ISO coding, CAD-CAM systems.

Structure of an NC program, path programming, G-codes.

Coordinate systems on the machine tool, reference point and offsets.

Tool radius compensation, compensated path.

Coordinate system transformation to machine tool axes.

Inaccuracy of machine tool, measuring methods and compensations.

Recapitulation: coordinate system offsets, tool radius compensation, transformations, inaccuracy compensation.

Subprograms, macros, canned cycles. Programming dialogue. Control modes.

Technical demands on CNC system. Inner structure of CNC (HW, SW).
