Advanced Complex Turning Operations for Machinists Training

Learning Outcomes

• Analyze advanced turning blueprints and specifications to determine optimal machining strategies.
• Design and implement complex CNC programs for multi-axis turning operations using G-code and CAM software.
• Demonstrate setup and operation of CNC lathes for intricate profiles, threads, and contours with tight tolerances.
• Evaluate tool selection, cutting parameters, and workholding methods to maximize efficiency and surface finish.
• Apply quality control techniques including in-process inspection and dimensional verification using precision instruments.
• Implement troubleshooting procedures to resolve common issues in complex turning such as chatter, tool wear, and dimensional deviations.

Target Audience

Experienced machinists and CNC operators who have completed basic turning training and wish to advance their expertise in complex turning operations. This course is ideal for those working in precision engineering, aerospace, automotive, or tool and die industries.

Prerequisites

None — open enrollment. However, a strong foundation in basic turning operations and CNC machining is highly recommended.

Course Outline

Practicals

Overview

The practicals component comprises 52 hours of supervised hands-on machining on CNC lathes. Learners will set up workholding, program and operate machines, and inspect parts using precision instruments. These sessions directly reinforce the daily theory and build competence in complex turning operations.

Practical Activities

• Practical 1: Workholding Setup and Tool Selection — Learners set up soft jaws, collet chucks, and steady rests; select and mount tools for turning, boring, and threading operations. (12h)
• Practical 2: Multi-axis Programming and Machining — Learners write and test CNC programs for C-axis, Y-axis, and live tooling operations, then machine a part with multiple features. (16h)
• Practical 3: Hard Turning and Exotic Alloys — Learners machine hardened steel (55 HRC) and a titanium alloy, applying appropriate cutting parameters and tool materials. (12h)
• Practical 4: Complex Threading and Eccentric Turning — Learners program and cut multi-start threads and eccentric features on a single workpiece, then inspect using thread gauges and dial indicators. (12h)

Summatives

Each delegate is assessed continuously throughout the course via daily exercises, scored practical assignments, and a final summative test at the end.

Practical Assignments — 30%

Practical assignments are observed and scored against a rubric during the practical sessions. Each delegate's practical mark is averaged into a single 100% score and contributes 30% to the final total.

Daily Exercises — 20%

Every training day ends with a multiple-choice exercise scored out of 100%. The scores from each daily exercise are averaged across the duration of the course to produce a Daily Average mark, which contributes 20% to the final total.

Final Test — 50%

On the last day a final summative test is written. It is a multiple-choice paper with multiple-answer questions: each question may have more than one correct option, and a single wrong selection on a question marks the entire question wrong — no partial credit. The final test is scored out of 100% and contributes 50% to the overall mark.

Final Total

Component	Out of	Weight
Practical Assignments (rubric-scored)	100%	30%
Daily Average (multiple choice)	100%	20%
Final Test (multi-answer multiple choice)	100%	50%
Final Total	—	100%

All marks are recorded on the AATICD LMS and visible to each learner under their account.

Certificate

How it works

• Certificates are auto-generated on the AATICD LMS as soon as the marks pass the 50% threshold.
• Each certificate is a branded PDF with the delegate's name, the course title, the unit standard ID, NQF level, credits, and the date of issue.
• You can download or print your certificate from your LMS dashboard at any time after issue — there's no reissue fee and no expiry date.
• If you scored under 50% you can sit the final test again at the next scheduled session at no extra cost.

Where to find it

Sign in to the LMS, open your dashboard, and your certificates appear under My Certificates. Each entry has a View / Download button and a print option.
