Step-by-step explanation:
A good analogy to what happens in a CNC program is to visualize the assembly of a car. Let's say you build cars in a factory. The factory is equipped with all kinds of machines and people to make sure the cars are built correctly. At each workstation, a specific action is performed to add more parts to the car. Similarly, in a CNC program, a series of instructions are followed to guide the machine in performing specific actions to create a product.
