However, due to its molecular structure, it exhibits poor mechanical properties.
However, the higher filler loading in composites often results in weak mechanical properties and increase in porosity [19].

Introduction
Advanced ceramic is one of the dominant materials used widely in modern industry, due to its outstanding mechanical and physical properties like high thermal resistance, high hardness and chemical stability.
Photo of UV curing system Hardness and Abrasion The hardness of lapping plate is one of the key factors because the lapping plate undergoes load and produce deformation during the lapping process.
The certain hardness of the lapping plate may keep the grain in the situation of scraping or rolling, thereby affecting the material removal rate and surface roughness of the woke-piece.
Furthermore their wearing properties were compared by lapping those samples under the same machining conditions and then measuring the loss of thickness of the samples.

In some cases are often required unique material properties.
However, different material properties of matrix and reinforcing phase cause problems during conventional machining, such as delamination of composite and rapid tool wear.
However, different mechanical properties of each compound in composite material is challenging to machine.

However, the formability of tapered part was restricted by many factors, such as mechanical properties of metal, blank holding force (BHF), drawbead resistance, friction coefficient between die and blank, etc.
The detailed mechanical properties of material are listed in table 1.
Actually many factors should be considerate in the forming process as analyzed above.
Factors and levels of the experiment are given in table 2.
Especially, the drawbead resistance and friction coefficient affect more on the forming performance than the other factors according to the simulation result.

The results provide insights into the effects of die angle on the material's deformation behavior and mechanical properties, offering a foundation for optimizing the ECAP process for AA6061.
The development and refinement of these techniques aim to enhance the mechanical properties of metals for sophisticated applications [3].
Instead, other factors such as the number of passes and the material's properties may have a more significant influence on the billet's stress distribution and subsequent mechanical improvements.
This uniformity is crucial to ensuring consistent plastic deformation across the billet, leading to improved grain refinement and enhanced mechanical properties of the material.
