The thread is divided into three sections for processing, and the G32 command is used to ensure that the position of each segment of the thread receiving tool (lower tool) is on the thread track. As the thread segment processing includes cut-in and cut-out, it is completed with three G32 instructions: cut-in + cutting thread + cut-out three parts for thread processing in sections;

Calculate the relationship between the axial feed, the angle of the spindle rotation and the axial movement of the tool when cutting in and out. It must be ensured that each cutting point of the knife cuts to the bottom diameter of the thread, and the angle of the cut-in and cut-out matches the rotation angle of the spindle and the distance of the tool's axial movement.
