① According to the drawings and process plans of the processed parts, write the processing program using the specified code and program segment format; ② Input the programmed machining program instructions into the CNC device of the machine tool; ③ After the numerical control device processes the program (code), it sends control signals to the servo drive mechanism and auxiliary control device of each coordinate of the machine tool; ④ After receiving the execution signal command, the servo mechanism drives various moving parts of the machine tool and controls the necessary auxiliary actions; ⑤ The machine tool automatically processes qualified parts;
1. Regulations on the coordinate system of machine tools
The mutual relationship between the X, Y, and Z coordinate axes in the standard machine tool coordinate system is determined by the right-hand Cartesian Cartesian coordinate system, as shown in the figure:
Extend the thumb, index finger, and middle finger of the right hand at 90 degrees to each other, with the thumb representing the X coordinate, index finger representing the Y coordinate, and middle finger representing the Z coordinate;
The pointing of the thumb is in the positive direction of the X coordinate, the pointing of the index finger is in the positive direction of the Y coordinate, and the pointing of the middle finger is in the positive direction of the Z coordinate;

3. Workpiece coordinate system and program origin
Definition: The workpiece coordinate system is used by programmers during programming. Programmers select a point on the workpiece as the origin (also known as the program origin) and establish a coordinate system called the workpiece coordinate system. Once the workpiece coordinate system is established, it remains valid until it is replaced by a new workpiece coordinate system.
