Effects of drilling parameters on TI-6Al-4V alloy using different coolants

The formulation or application of coolants plays a critical role in machining to bring out the best finished products. In this scientific article, the study focused on the effects of coolants and machining parameters of Ti-6Al-4V are investigated with consideration of their performances by using drilling operation. The design of experiments (DOE) was considered and the performance of machining was measured with respect to cutting temperatures and surface responses. The final results put forward that the excellent surface finish and minimal cutting temperatures are obtained by application of power metcut s plus when compared with pure water. The factors that impact the surface roughness of Ti-6Al-4V are coolant and feed rate. The coolant also helps in the machining process by reducing temperature at the cutting zone

FABRICATION OF PADDY TRANSPLANTER MACHINE

India is an agrarian country. About 58% of Indians are dependent on agriculture for their livelihood. At least 12 crore families in India are dependent on agriculture. India is world's second largest producers of rice, accounting for 20% of all world rice production. Rice is usually grown by planting paddy in the fields manually. A major population of India is engaged in agriculture. Rice being the major crop cultivated in India, a huge amount of workforce is engaged in rice production. The common practice of rice cultivation is manual transplanting of seedlings in the puddled soil. Rice is primary and major crop cultivated in India. As the large workforce is engaged in this sector, Traditional method is costly, time consuming and labor intensive work. To make the transplanted system several attempt has been made to design and fabricate this machine. So our main of our project is to design and fabricate a paddy transplanted by using this machine we use decrease the labor cost and increased the productivity. So this machine works on a simple mechanism which is easy to maintain and it is eco-friendly. And no skilled labors are required, only single person is required to operate the machine. In this work, the difficulties while planting the seedlings in the field by the farmers are eliminated. View Article DOI: 10.47856/ijaast.2022.v09i07.00
