What is the function of a probe in CNC milling?

• A. To perform cutting operations
• B. To measure features and ensure the workpiece is aligned
• C. To calibrate the machine's settings
• D. To apply coolant during machining

Answer: (B)

The function of a probe in CNC milling is to measure features and ensure proper alignment of the workpiece. Probes are essential tools that interact with the workpiece surface to gather precise measurements of its dimensions and features. By doing so, they enable the machine to adjust its operation and verify that it is set up correctly, enhancing accuracy and reducing the likelihood of errors during machining. This process can involve measuring the locations of holes, distances between features, and checking surface heights, which ensures that all machining operations occur within the desired tolerances. The use of a probe contributes significantly to the overall efficiency and precision of the milling process. It can help in both setup and in-process adjustments, making it an invaluable tool in CNC operations.
