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.
