What does MDI stand for in CNC terminology?

MDI stands for Manual Data Input in CNC terminology. This mode allows an operator to input commands directly into the CNC machine's control system without relying on pre-programmed instructions. It is particularly useful for running quick jobs or for testing specific functions of the machine, as it enables the operator to enter specific codes for machining operations manually.

By using MDI, operators can directly control the movement of the machine axes, adjust tool positions, and execute programs or commands on the fly. This contributes to flexibility during setup or troubleshooting, as operators can test their machine's response to specific commands before running a full machining cycle. MDI mode is essential for those working with CNC machines, as it enhances control and precision in custom machining tasks.
