Machinability of Metal Materials in CNC Machining
1. Material Toughness
Toughness is expressed by impact value. The higher the toughness of the material, the more energy is consumed during cutting, the cutting force and cutting temperature are also higher, and it is not easy to break chips, so the workability is poor. Some alloy structural steels are not only stronger than carbon structural steels, but also have higher impact values, so they are more difficult to process.
Other physical and mechanical properties also have a certain influence on the machinability. For example, materials with a large linear expansion coefficient will expand and contract during processing, and the size of the workpiece will vary greatly, so it is not easy to control the accuracy. The material with low elastic modulus has a large elastic recovery during the forming process of the processed surface, and it is easy to cause strong friction with the flank surface.
2. The Strength and Plasticity of the Material
In terms of the hardness of the workpiece material (including room temperature hardness and high temperature hardness), in general, the high room temperature hardness of similar materials has low workability. Because when the material hardness is high, the contact length between the chip and the rake face is reduced, so the shear stress on the rake face increases, and the frictional heat is concentrated on the smaller tool-chip contact surface, which promotes the increase of cutting temperature and increased wear. If the hardness is too high, it will even cause burning of the tip and chipping. Take steel as an example, steel with moderate hardness is better processed. In addition, appropriately increasing the hardness of the material is conducive to obtaining better processed surface quality. The plasticity of a material is usually expressed in terms of elongation. Generally, the greater the plasticity of the material, the more difficult it is to process. Because of the large plastic material, processing deformation and hardening, and cold welding of the tool surface are more serious, it is not easy to break chips, and it is not easy to obtain a good, processed surface quality.
The surface quality of the workpiece is closely related to its performance. The performance of the workpiece is the design requirement to ensure the normal operation of the machine. Therefore, in the cnc metal machining, economic benefits should also be considered to ensure the processing of the surface of the workpiece. Quality, to avoid increasing the manufacturing cost of parts and causing unnecessary losses. Only by understanding and mastering the factors that affect the surface quality of mechanical processing can we take corresponding process measures in production practice to reduce processing quality problems caused by surface quality defects of parts, thereby improving the performance, life and reliability of mechanical products.
