CNC precision machining requires a high level of skill, the following are some of the key skills and knowledge required:

Mechanical knowledge: understanding of the basic principles of machining, including materials science, metal working technology and mechanical manufacturing processes.

CNC programming: Knowledge of CNC programming languages (e.g. G-code and M-code) and the ability to write and modify CNC programs.

Skills: Familiar with CNC machine interfaces and control panels, able to accurately set up and machine.

Drawing Reading Skills: Ability to read and understand engineering drawings and technical specifications, including 2D and 3D drawings.

Measuring techniques: Acquire the skills to perform precision measurements using a variety of measuring tools (e.g. calipers, micrometers, height gauges, etc.).

Tool Knowledge: Knowledge of different types of tools and their uses, including tool materials, dimensions and cutting parameters.

Machine Maintenance: Knowledge of routine maintenance and care of CNC machine tools, including lubrication, cleaning and inspection.

Problem Solving: Ability to analyze and solve problems that occur during machining, such as tool wear, machining errors, etc.

Quality Control: Understand the quality control process and be able to perform inspection and quality assurance of machined parts.

Computer Skills: Proficient in the use of Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) software.

Awareness: Strict adherence to protocols, good sense and emergency response skills.

Communication and Coordination: Communicate effectively with team members, engineers and management to ensure successful completion of machining tasks.

Continuous Learning: As technology continues to advance, personnel need to continually learn new skills and knowledge to adapt to new machining techniques and equipment.

Project Management: In some cases, personnel may be required to manage small projects, including time management, resource allocation and schedule control.
