1. Workpiece preparation and clamping: the workpiece needs to be prepared and clamped on the lathe. In the process of clamping, attention should be paid to the position and clamping strength of the workpiece to ensure the accuracy and stability of machining.

2. Tool selection: Generally, when selecting a tool suitable for machining a workpiece, factors such as machining material, aperture and depth need to be considered. At the same time, the length and cutting angle of the tool will also affect the machining effect, so it needs to be carefully selected.

3. Setting of programming parameters: During programming, parameters such as tool feed speed, cutting speed and cutting depth need to be set to ensure machining accuracy and efficiency. Especially for deep hole machining, we should pay attention to the setting of cutting depth and tool withdrawal distance to avoid tool fracture or workpiece deformation.

4. Monitoring of machining process: In the machining process, it is necessary to constantly monitor the machining state, especially the tool wear and workpiece deformation. If necessary, change the cutter or adjust the cutting parameters in time to ensure the machining quality and efficiency.
