The introductory CNC programming course is intended for vocational educators at technical institutions, technology teachers, entry-level engineers, and all individuals seeking both theoretical and practical foundations for working with computer numerically controlled (CNC) machines. Participants are systematically introduced to the operational logic of CNC machines, coordinate systems, the structure and sequence of fundamental G and M codes. Basic applications of CNC tools are presented, including demonstrations of simple 2D-2.5D machining examples. Emphasis is placed on safe working practices, the selection of cutting data and tools, the calculation of key cutting parameters, and programme testing in a simulation environment. The course provides essential knowledge required to correctly interpret simple technical drawings, plan machining operations, and create an initial functional CNC programme in accordance with industrial quality standards.
Explain the structural logic of CNC machines and the principles of three-axis motion control. Plan the technological process: interpret technical drawings, determine the sequence of operations, and prepare a programme outline for manufacturing. Select and input tools into the machine controller, accurately setting tool length and radius offsets within the control system. Calculate cutting parameters - spindle speed, feedrate, and depth of cut - and apply them appropriately within the programme. Develop a basic turning and 2D milling machining programme from the initial block to completion. Perform programme simulation on the machine controller and identify and correct common errors.
