Five-axis machining technology is a key technology for the precision
machining of aviation parts. It is necessary to adopt five-axis machining for
complex shapes and limited relative positions between the cutting tool and the
parts. Positioning five-axis machining can reduce clamping times and improve
machining accuracy. Each clamping will increase a workpiece error source,
thereby affecting the workpiece's final accuracy requirements.
The advantages of positioning five-axis machining include the effective use
of shorter tools, reduced tool extension length, faster-cutting speed, longer
tool life, improved machining accuracy, and improved surface quality simply by
creating a series of directional working planes. Moreover, using five-axis
machining, the workpiece only needs a few debugging and loading times, so as to
save time, reduce the error caused by many debugging and loading, and greatly
improve the utilization rate of the machine tool.
Programming five-axis machining is not as difficult as it sounds. It can find
some simple and practical programming methods through CAM software. These
software packages enable high-speed machining techniques to be well applied to
achieve higher cost-effectiveness.
Experienced users are able to create templates, saving time and reducing
errors for future programs, and are able to simulate the entire process on a
computer to avoid errors in shop floor processing. In preparation for the
application of five-axis machining, the user may need to adjust the strategy of
the fixture system to get as close to a large number of parts characteristics as
possible during the five-axis debugging and loading process. In general, it is
obvious that multiple sides of a workpiece cannot be accessed with a standard
workpiece fixture. A dedicated five-axis clamping device, chuck clamping
mechanism, and magnetic chuck allow the tool to be more freely accessible to the
parts to be processed.
The advantage of continuous five-axis machining is that it can eliminate the
mixing line and continuously keep the appropriate tool running in the surface
direction, which will be beneficial to improve the surface quality and prolong
the tool's life. In short, the advantages of cutting times are reduced, the
machining cycle is shortened and the one-time debugging Settings are conducive
to saving time, reducing setting errors, and being better close to the bottom
In general, the advantages of five-axis machining also include increased
efficiency of machine tools, that is, only one machine tool can be used for
three-axis HSM machining, positioning five-axis machining, continuous five-axis
machining and five-axis drilling machining, and many more processes. Generally
speaking, the axes of these machine tools have faster stroke speed and higher
spindle speed. In addition, the volume of the five-axis machining machine is
smaller and the rigidity is higher, which further improves the machining effect
of the machine tool.
However, with the continuous development of these factors, it is indeed found
that the cost of the five-axis machining process is skyrocketing. This is
usually due to a lack of understanding of the application of five-axis machining
in particular markets. Once the workshop is able to understand in many ways
where the benefits are to be gained, the controversy will quickly disappear.
These advances in technology may be expensive in the early stages of
development, but they will be offset by greater advantages in tool life,
efficiency, and operating costs.
