The experimental results presented that the dimensions of burr could reduce greatly by the proposed PMMA coating method compared to materials without coating.
However, owing to its properties of poor heat conduction, high chemical reactivity and low elastic modulus, titanium alloy easily reacts to tool materials at high temperature caused by narrow cutting zone, which makes it be considered as typical difficult-to-machine materials.
Toropov et al[6] established a prediction model for burr formation in machining of ductile materials.

A new burr formation model for orthogonal cutting of ductile materials[J].

The materials input in the process include energy, water and raw materials. 
Water and gangue are the main materials could be recycled.
The amount of recycled materials was 9,733,400t and material consumption was 73,378,500t. 
Recycled materials account for 5.24% of total material requirements.

This indicates that the seeded thin films have lower structural defects, oxygen vacancies and impurities because of the presence of seeded TiO2 as supportive materials [18] .
Raman analysis confirmed that the appearance of all corresponding ZnO and TiO2 peaks confirmed the existence of mixed crystalline structure of both materials in the TiO2: ZnO thin films.
This indicates that the seeded thin films have lower structural defects, oxygen vacancies and impurities because of the presence of seeded TiO2 as supportive materials.
