(I) Requirements for Operators and Maintenance Personnel of CNC Machine Tools CNC machine tools are controlled by computer systems, which makes their drive mechanisms technically complex and demands high precision from the mechanical components. As a result, operators, maintenance staff, and managers must have a strong educational background and a well-rounded technical skill set. The operation of CNC machines is based on pre-programmed instructions. For simple parts, manual programming is possible, but when dealing with more complex geometries, the programming workload increases significantly. Manual programming becomes time-consuming and prone to errors, making it necessary to use computer-aided programming. Therefore, CNC operators should not only possess basic machining knowledge and experience with traditional machine tools but also have a thorough understanding of the structure and working principles of CNC machines. They should be proficient in computer operations and skilled in programming. Only after passing a proper training and assessment can they be authorized to operate the machines. Proper maintenance is essential for the efficient and safe operation of CNC machine tools. Maintenance personnel must have strong theoretical knowledge and practical skills in maintaining these advanced systems. They need to understand both the mechanical structure and the electrical and electronic components of the machine. A broad range of expertise in mechanics, electricity, pneumatics, and hydraulics is also required. This comprehensive knowledge enables them to accurately diagnose faults and perform effective repairs, ensuring the machine remains in optimal working condition. Thus, both operators and maintenance personnel must undergo specialized training before being allowed to work independently. (II) Requirements for Fixtures and Cutting Tools in CNC Machine Tools CNC machine tools typically require simpler fixtures, especially in single-piece production where general-purpose fixtures are commonly used. However, in mass production, special fixtures are recommended to reduce processing time. These fixtures must be reliable, capable of automatically clamping or releasing the workpiece, and designed to ensure good chip removal and cooling performance. In addition to the fixtures, the cutting tools used in CNC machines must meet certain standards. They should have the following characteristics: (1) High accuracy, long durability, stable geometric shape, and minimal deformation. (2) The ability to be pre-adjusted and quickly replaced. When machining high-precision holes, the tool must be measured and adjusted accordingly. (3) The tool shank must conform to standard specifications. (4) Effective control over chip breaking and chip evacuation. (5) Excellent cooling performance to maintain tool integrity and improve machining quality.
