John had heard about FANUC's FOCAS (FANUC Open CNC API) library, which allowed developers to create custom applications to control FANUC CNC machines. He decided to use Python, a language he was familiar with, to create a program that could communicate with the CNC machine using FOCAS.

import focas

# Create a Focas object cnc = focas.Focas("192.168.1.100", 8193) # IP address and port of the CNC machine

# Execute a program on the CNC machine cnc.exec_program(" machining_program")
