1.Roughness
Laser cutting cross section will form a vertical lines, the depth of the texture of the cut surface of the roughness of the cut surface,
the more shallow lines, the more smooth cut section. Roughness not only affects the appearance of the edges, but also affect the
friction characteristics, in most cases, it is necessary to minimize the roughness, so the more shallow texture, the higher the quality
of the cut.

2. Verticality
If the sheet thickness exceeds 10mm, the verticality of cutting edge is very important. Away from the focus, the laser beam
becomes divergent, according to the location of the focus, cutting to the top or bottom of the variable width. Cutting edge off the
vertical line of a few millimeters, the edge of the more vertical, the higher the quality of cutting.

3. Cutting width
Kerf width generally does not affect the cutting qualit, only in the internal components formed special precision contour, cutting
width is important. This is because the cutting width determines the contour of the minimum, when the plate thickness increases,
the cutting width also increases. So want to guarantee the same high precision, no matter how much the width of the cut, the
workpiece in the laser cutting machine processing area should be constant.

4. Lines
High speed cutting thick plate, the molten metal will not appear in the vertical laser beam below the incision, but will be sprayed out
at the laser beam side. As a result, the curved lines are formed on the cutting edge, and the lines are closely followed by the laser
beam. In order to correct the problem, the feed rate can be reduced at the end of the cutting process.

5. Burr
Burr formation is a very important factor to determine the quality of laser cutting, because the removal of burr need extra work, so
the amount of burr is serious and how much is able to directly determine the quality of cutting.

6. Material Deposition

special iqud Gsiaion and al kndns omlaease,s the mateial does not neto use the wind o blow he cut, but the upwardor
downward discharge also can form the depsition on the surface.

7. Sag and Corrosion
Sag and corrosion have adverse effects on the surface of the cutting edge, affecting the appearance. They appear in the error of the
cut which is generally supposed to be avoided.

8. Heat Affected Zone
In the laser cutting,the area in the near the notch is heated, At same time, the structure of the metal changes ,For example ,some of the

metal can be hardened , the heat affected zone refer to the depth of the area that is changed by the internal structure.

9.Deformation

If the cutting makes the component heat , it will deform . This is particularly important in fine processing ,

because the profile and connection pieces are usually only a few millmeters wide . Control of laser power 

and use of short laser pulses can reduce the parts become hot to avoid deormation.

Features
High Accuracy
CNC machines are highly integrated mechatronic products, which are composed of precision machinery and automatic control
systems. They have high positioning accuracy and repeat positioning accuracy. The transmission system and the structure have
high rigidity and stability to reduce errors. Therefore, CNC machine has higher machining accuracy, especially the consistency of
parts manufacturing in the same batch, and the product quality is stable, the pass rate is high, which is incomparable with ordinary
machine tools.
High Efficiency
CNC machines can use a larger amount of cutting, which effectively saves processing time. CNC machines also have automatic
speed change, automatic tool change and other automatic operation functions, which greatly shorten the auxiliary time, and once a
stable processing process is formed, there is no need to perform inter-process inspection and measurement. Therefore, the
productivity of CNC machining is 3-4 times higher than that of ordinary machine tools, or even more.
High Adaptability
CNC machine performs automatic processing according to the CNC program of the processed parts. When the machining object
changes, as long as the CNC program is changed, there is no need to use special process equipment such as masters and
templates. This is helpful to shorten the production preparation cycle and promote product replacement.
High Machinability
Some mechanical parts formed by complex curves and curved surfaces are dificult to process or even impossible to complete with
conventional techniques and manual operations, and can be easily realized by CNC machines using multi-coordinate axes linkage.
High Economic Value
CNC machining centers mostly use process concentration, and one machine is multi-purpose. In the case of one clamping, most
parts of the parts can be processed. CNC machining center can replace several ordinary machine tools. This can not only reduce
clamping errors, save auxiliary time between transportation, measurement, and clamping between processes, but also reduce the
types of machine tools, save machine tool area, and bring higher economic benefits.
