Machining parts on an automatic CNC lathe usually goes through the following steps:
1. According to the drawings and process plans of processed parts, compile the program sheet with the specified code and program format, and record it on the carrier.
2. Input the program on the program carrier into the CNC unit through the input device;
3. After processing the input program, the CNC unit sends signals to the servo system of each coordinate of the machine tool;
4. The servo system drives the moving parts of the machine tool and controls the auxiliary operation according to the signal sent by the CNC unit;
5. Drive the relative movement between the cutter and the workpiece through the mechanical parts of the machine tool to process the required workpiece;
6. Detect the movement of the CNC lathe and feed it back to the CNC unit through the feedback device to reduce the machining error. Of course, there is no detection and feedback system for open-loop CNC lathe.
