In the process of changing the hair planter from a blank into a product, the total thickness of the metal layer removed from a processing appearance is called the total processing margin of the appearance. The thickness of the metal layer removed by each operation is called the inter-process machining margin. For the rotating appearance of outer circles and holes, the processing margin is considered from the diameter, so it is called symmetrical residual (i.e., the balance of margin), that is, the thickness of the metal layer removed by practice is half of the processing margin on the diameter. The machining margin of the plane is the unilateral margin, which is equal to the thickness of the metal layer cut by practice. The purpose of leaving the processing margin on the workpiece is to remove the processing errors and appearance defects left behind by the previous process, such as the pre-cold hard layer, pore, sandwich layer, the oxide skin of the forging appearance, the decarbonization layer, the appearance crack, the internal stress layer after cutting and the roughness of the exterior. This improves the accuracy of the workpiece and the roughness of the exterior. The size of the processing margin has a great influence on the processing quality and production power. Processing margin is too large, not only increases the amount of labor in machining, reduces the production rate, but also increases the cost of data, tools and electricity, and increases the processing cost.
