What is one key advantage of using CNC machines over manual machines?

CNC machines offer the significant advantage of being able to operate for extended periods with minimal supervision. This capability allows them to run continuously, making them highly efficient for mass production and complex machining tasks. While a human operator would need to be present to monitor and control manual machines closely, which can limit productivity due to the need for human attention and intervention, CNC machines can autonomously execute programmed operations. This automation not only reduces the need for constant oversight but also enhances consistency and precision in production, as the programmed instructions result in uniformity across multiple parts produced in succession. The ability to operate unattended for longer durations allows manufacturers to optimize workflow, reduce labor costs, and increase output levels, marking a clear advantage over manual machining processes.
