CNC Turning Manual Programming

Description

This course provides a practical introduction to CNC turning machines and manual part programming. It covers CNC lathe fundamentals, axis designations, programming structure, G-codes, M-codes, turning tools, tool nose radius compensation, and canned cycles. Participants will learn to prepare CNC programs for facing, turning, drilling, boring, grooving, profiling, and threading operations.

Course Details

CNC Turning Manual Part Programming course is designed to provide a strong foundation in CNC turning machine operations and manual programming.

The course covers workshop safety, measuring instruments, CNC lathe machine parts, axis designations, machine specifications, programming nomenclature, program structure, commonly used G-codes and M-codes, cutting tools, inserts, tool nose radius compensation, and CNC canned cycles.

Participants will learn to prepare CNC turning programs for facing, straight turning, step turning, taper turning, profile machining, drilling, boring, grooving, threading, roughing, and finishing operations. Module-wise exercises and assessments help participants evaluate their understanding and improve their programming skills.

Course Duration: 3 Weeks

Participants are advised to spend approximately 2–3 hours per day completing online lessons, programming exercises, and assessments.

Course Access : Participants will receive 6 months of online course access from the date of enrolment.
