What does a machine require for effective CNC operation when using g-code?

Skillful manual adjustments
No need for programming
Flexibility to change g-code
Constant human supervision

The correct answer is: Flexibility to change g-code

A machine requires the flexibility to change g-code for effective CNC operation because g-code is a programming language used to control CNC machines. This programming language consists of a series of commands that dictate the machine's movements and actions, allowing it to perform various operations with precision. The ability to modify g-code is crucial as it enables operators to customize settings for different materials, designs, and production runs. Changes can involve adjusting feed rates, tool paths, or other parameters to optimize the machining process, ensuring precision and efficiency. This flexibility allows for adaptability in production, accommodating varying project requirements or correcting any issues that may arise during operation. While having skillful manual adjustments might seem beneficial, effective CNC operation primarily relies on automated programming rather than manual input. Also, the notion of no need for programming overlooks the fundamental need for directing the machine's functions through g-code commands. Lastly, while constant human supervision can enhance safety and troubleshooting, modern CNC operations are designed to run autonomously once set up, thus reducing the need for incessant human intervention.
