erimental Investigation of Process Parameter on Tensile Strength of Selective...ijsrd.com
Selective Laser Melting (SLM) is an emerging, fast growing rapid prototyping (RP) technology due to its ability to build functional parts having complex geometrical shape in reasonable time period. The quality of built parts highly depends on many process variables in selective laser melting. In this study, three important SLM process parameters such as layer thickness, orientation angle and scan speed are considered. Their influence on tensile strength of test specimen is studied. Margining Steel having grade 1.2709 was the material, commercially named CL50WS, which is used for fabricate Tensile Specimen in SLM. The experiments are conducted based on Taguchi's L8 orthogonal array. The validity of process parameter and response is tested by using analysis of variance (ANOVA). The multi linear regression model is developed in order to predict Tensile strength of test specimen. The experimental data and data obtained by regression equation is closely correlated which validated the models. The layer thickness and scan speed is highly affect the quality of SLM fabricated parts whereas orientation angle have little important.
Investigation on Optimization of Machining Parameters in Wire EDM using Taguc...ijsrd.com
In this paper, the parameters used in the cutting of Cemented Tungsten Carbide using wire electrical discharge machining (WEDM) with a Brass electrode was optimized using Taguchi method. Taguchi method is used to formulate the experimental layout and to analyze the effect of each parameter on the machining characteristics. Also it is used to predict the optimal choice for each parameter such as peak current, voltage, and pulse duration and interval time. It was found that these parameters have significant influence on machining characteristics such as Metal Removal Rate (MRR) and Surface Roughness (SR). The result of the work reveals that, the peak current significantly affects the Surface Roughness (SR) and the pulse duration mainly affects the Metal Removal Rate (MRR).

This paper is done essentially to study results of
Alumina (Al2O3
), Zirconia (ZrO2
) and Alumina-Zirconia
(Al2O3+40%ZrO2
) ceramic coatings by using plasma spray
process, with different coating thickness of 100μm, 150μm and
200μm are deposited on Al-7075T6 substrate. Coating
microstructure were characterized by using SEM. The coating
Micro hardness, Tribological behaviour and Surface Roughness
of the coated specimens were determined for Aluminium (Al-
7075T6) and Coated Al-7075T6. NiCrAl is used as a bond coat
for providing better coating adhesion. Dry sliding wear test were
performed for different sliding distance of 1000m, 2000m, and
3000m at a constant load of 10N by using a Pin-on-Disc. From
the above work the results were obtained it showed that,
Alumina-Zirconia (Al2O3+40%ZrO2
) coated specimens having
very good wear resistance property when compared to
Alumina (Al2O3
), Zirconia (ZrO2
) coating materials. These results
clearly demonstrate that the significant improvement in coating
performance can be achieved by proper thermal spray conditions
and proper mixing of coating powder composition.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.
