DOE is widely used to predict the bead geometry and mechanical properties in many welding process [4].
This procedure creates designs with desirable statistical properties, but most importantly with only a fraction of the experiments required for three-level factorials.
For this study, since a three-level factor requires all possible pairs of 22 designs, three-level factors will be required total possible pairs of 3(22) plus three replicates at the center making a total of 15 experimental trials.
The S/N ratio is a measure of performance to develop products and processes insensitive to noise factors.
The S/N ratio is the main experimental robustness evaluation index, to ensuring that all experimental factor information and test factors affecting the experimental objectives are determined on the impact on the experimental objectives by a small number of experiments.

For instance, Hossein Mani et al. [1] evaluated the mechanical-thermal properties and microstructure of the RFW process using the finite element method.
Thermal properties change with temperature.
It reflects the degree of material deformation and loss during the process, directly influencing the mechanical properties and dimensional stability of the welded joint.
These areas are likely to experience phase changes, altering the material structure and affecting weld quality.
After 4 seconds, the curve stabilizes, reflecting that the deformation process has stopped as factors such as temperature and pressure have reached equilibrium.

In addition, other factors to consider are the cost of paper production.
The aim is to see the reaction on mechanical properties that applied to the resulting sample.
Among the factors the increase is due to the thickness of the test specimens are thicker than others.
This is because there are many factors that cause these things.
Furthermore the mechanical properties, electrical properties, and chemical properties of natural fibers are very good as a place of choice in the manufacturing sector.

Chemical composition, physical structure, surface properties and mechanical properties of scaffolds are necessary factors to enhance the cell-scaffold interaction [8-11].
Nano-HA and FHA have ability to increase mechanical properties such as compressive strength and modulus and biocompatibility of scaffold [18-20].
In addition, scaffolds need sufficient mechanical properties to support mechanical forces during implantation and tissue regeneration process.
Nano HA and FHA particles could play as a reinforced component in polymeric composite scaffold due to its superior mechanical properties [27-29].

Experimental study on the water-cement ratio, coarse aggregate rate ratio factors on the strength of lightweight aggregate concrete.
1 Introduction
Lightweight aggregate concrete (LWAC) becomes a hot topic in the research areas of building materials because of their many advantages of lightweight, high strength, thermal insulation, fire resistance, acoustic, seismic performance good.
Concrete is a heterogeneous combination of materials, physical and mechanical properties are determined by the internal structure to the preparation of a high-strength lightweight aggregate concrete, must start from the design and construction process of the development of raw materials and proportioning.

Thermal properties are one of the most important factors
that determine the usage of a material.
Secondly, heat treatment is needed in some cases for natural fibers to improve the mechanical properties of the resulting composites.
When natural fibers are used as a reinforcement in composites, a quick process and a dry environment is necessary to minimise moisture absorption, as water content in natural fibers is a critical factor affecting the properties of hemp fiber composites.
Hemp fiber composites were made using different methods and the mechanical properties of the resulting composites were compared at Table 3.
There is hardly any reinforcing effect in this case and higher fiber fraction is required to achieve better mechanical properties.

The results
show that the feed rate and drill type are the most significant factor affecting the induced-thrust in
drilling CFRP laminates.
Introduction Owing to composite materials have the superior mechanical properties when compared against conventional metal, like strength and stiffness, the use of composite parts is increasing within the design of structural elements in aerospace, automobile and marine industries.
The influence of each control factor (A, B and C) on the quality character factors (thrust force) was analyzed from the S/N ratio response table.
A bigger control factor level difference means a greater influence on the quality character factors.
In Table 4, the most important variables affecting the thrust force are feed rate (P = 50.9 %) and followed by the drill type (P = 44.4 %).
