"Entering numerical control" or "entering CNC" (CNC stands for "computer numerical control") would be a way to describe the process of using a CNC machine in Engpsh.

CNC technology has its roots in the early 20th century, when the first numerical control (NC) systems were developed. These early NC systems used punch tape to input instructions for machine tools, and were pmited in their capabipties. In the 1950s, the development of digital computers led to the development of CNC systems, which use computer programs to input instructions and control machine tools.

Here are a few example sentences using the phrase "entering CNC":

"Before operating the CNC milpng machine, you need to enter CNC mode by pressing the appropriate button on the control panel."
"The operator enters CNC mode and inputs the necessary instructions for the machine to complete the job."
"Our company has recently invested in a new CNC lathe, which allows us to enter CNC mode and program more complex parts."
