Background:
As an important method of remanufacturing, laser cladding can be used to obtain the parts with
specific shapes by stacking materials layer by layer. The formation mechanism of laser cladding determines the “Staircase
effect”, which makes the surface quality can hardly meet the dimensional accuracy of the parts. Therefore, the subsequent
machining must be performed to improve the dimensional accuracy and surface quality of cladding parts.
Methods:
In this paper, chip formation, cutting force, cutting temperature, tool wear, surface quality, and optimization of
cutting parameters in the subsequent cutting of laser cladding layer are analyzed. Scholars have expounded and studied
these five aspects but the cutting mechanism of laser cladding need further research.
Results:
The characteristics of cladding layer are similar to that of difficult to machine materials, and the change of
parameters has a significant impact on the cutting performance.
Conclusion:
The research status of subsequent machining of cladding layers is summarized, mainly from the aspects of
chip formation, cutting force, cutting temperature, tool wear, surface quality, and cutting parameters optimization. Besides,
the existing problems and further developments of subsequent machining of cladding layers are pointed out. The efforts are
helpful to promote the development and application of laser cladding remanufacturing technology.
