Module 4. CNC Controller and Software - Overview of the CNC controller's interface and
functions. G-code programming basics. Loading and editing CNC programs. Homing and
referencing procedures.
Module 5. Tooling and Workholding - Selection and installation of cutting tools and tool holders.
Proper clamping and securing of workpieces. Tool length and diameter compensation.

Module 6. Workpiece Setup and Fixturing - Proper workpiece positioning and alignment. Setting
workpiece zero or reference points. Techniques for achieving desired machining outcomes.
Module 7. Operating the CNC Machine - Powering on/off and emergency stop procedures.
Loading and executing CNC programs. Controlling spindle speed, feed rates and axis movements.

Module 8. Cutting Strategies and Machining Techniques - Understanding different cutting
operations: facing, drilling, milling, etc. Optimizing tool paths for efficiency and surface finish.
Consideration of tool wear and tool life.

Module 9. Quality Control and Inspection - Use of measuring tools (callipers, micrometres, etc.)
for dimensional verification. Checking workpiece quality and surface finish. Identifying and
addressing machining defects.

Module 10. Troubleshooting and Maintenance - Recognizing common machining issues and
their solutions. Troubleshooting mechanical, electrical, and software-related problems. Routine
maintenance tasks and schedule.

Module 11. Safety Practices - Importance of personal protective equipment (PPE). Safe machine
operation and hazard awareness. Emergency procedures and response.
Module 12. Advanced Topics (Optional, for more in-depth training) - CAD/CAM software usage
for generating CNC programs. Multi-axis machining techniques. Complex toolpath generation
and optimization.
Module 13. Practical Hands-On Training - Guided practice sessions on the CNC machine, starting
with simpler tasks and progressing to more complex operations. Application of learned concepts
to real machining projects.

Module 14. Assessment and Certification - Written and practical assessments to evaluate
operator competency. Issuing certificates upon successful completion of training.

It's important to customize the training curriculum based on the specific CNC machine, the
operator's prior experience, and the intended machining tasks. Practical hands-on training,
safety emphasis, and gradual progression from basic to advanced topics will ensure that
operators are well-equipped to operate the digital machine effectively and safely.

3.9 Forming – process and equipment in digital version

Forming processes are manufacturing methods used to shape and deform materials into desired
shapes or geometries. These processes involve the application of force, heat, or a combination
of both to alter the material's structure without removing any material. Forming processes are
widely used in various industries to create a wide range of products. Forming process is actually
a family of processes that are presented in Table 3.2.
