Lesson 1Simple CNC Program Setup and Usual G-code/M-code Parts for CheckingThis lesson shows simple CNC program setup, main G and M codes, and how to read sections, notes, and tool calls so machine runners can check programs for safety, right movements, and fitting with the setup in local factories.
Program header, safety lines, and commentsTool call, spindle speed, and coolant commandsLinear and circular motion G-code essentialsWork coordinate systems and tool length offsetsCommon M codes for spindle, coolant, and program endLesson 2Steps for Strange Situations Found Before Starting (Marking, Telling, Separating, Starting Fixes)This lesson explains right ways to handle strange findings before starting, like marking, separating, telling the right people, and starting fixes, while stopping unsafe shortcuts or fixes without permission in South Sudan plants.
Recognizing critical versus minor abnormalitiesApplying tags and documenting out-of-service statusIsolating energy sources when hazards are presentNotifying supervisors and maintenance promptlyRecording issues in logs or digital systemsLesson 3Needed Protective Gear for CNC Work and Why (Eye Guards, Ear Guards, Cut-Proof Gloves, Aprons, Safe Shoes)This lesson lists needed protective gear for CNC milling, why each is important, and how to pick, check, and use it right, connecting dangers like flying bits, loud noise, and sharp edges to specific guards for workers here.
