Answer: A. High processing accuracy, high production efficiency, low labor intensity of workers, can process complex surfaces, and reduce tooling costs.
This is a multiple-choice question that aims to identify the main advantages of CNC machine tools. We can find the correct answer by analyzing each item.
A. High processing accuracy, high production efficiency, low labor intensity of workers, can process complex surfaces, and reduce tooling costs:
- High processing accuracy: CNC machine tools use precision control systems to ensure processing accuracy.
- High production efficiency: High degree of automation, continuous and stable processing, and improved production efficiency.
- Low labor intensity of workers: Automated operation reduces the physical labor of workers.
- Can process complex surfaces: The flexibility and programming capabilities of CNC machine tools enable them to process parts of various complex shapes.
- Reduce tooling costs: Due to the precision and flexibility of CNC machine tools, the need for complex tooling can be reduced, thereby reducing costs.
This option fully and accurately describes the advantages of CNC machine tools.
B. High processing accuracy, high production efficiency, low labor intensity of workers, can process complex curved surfaces, low labor cost:
- "Low labor cost" does not directly reflect the advantages of CNC machine tools. The advantages of CNC machine tools mainly lie in improving production efficiency and processing accuracy, rather than directly reducing labor costs. Labor costs are affected by many factors, including workers' skill level, wage standards, etc.
C. High processing accuracy, committed to mass production, low labor intensity of workers, can process complex curved surfaces, and reduce mold costs:
- "Committed to mass production" Although CNC machine tools can be competent for mass production, this is not its most important or unique advantage. The advantage of CNC machine tools lies more in their high precision and ability to process complex curved surfaces.
- "Reducing mold costs" has little to do with the direct advantages of CNC machine tools. Mold costs are affected by many factors, including mold design, manufacturing materials, etc.
D. High processing accuracy, high production efficiency, high technical requirements for operators, ability to process complex surfaces, and reduced tooling costs:
- "High technical requirements for operators" is not an advantage of CNC machine tools, but may be seen as a challenge or requirement. One of the original intentions of the design of CNC machine tools is to reduce dependence on manual operation skills and improve production efficiency and processing accuracy.
In summary, option A most comprehensively and accurately describes the advantages of CNC machine tools.
Therefore, the answer is A: high processing accuracy, high production efficiency, low labor intensity of workers, ability to process complex surfaces, and reduced tooling costs.
