Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    MODELING AND SIMULATION OF CUTTING FORCES IN SURFACE GRINDING PROCESS AT MICRO LEVEL USING MATLAB
    (G. B. Pant University of Agriculture & Technology, Pantnagar-263145, 2023-02) Singh, Yogendra Kumar; Pankaj
    Grinding is a major manufacturing process that accounts for approximately 20– 25% of total machining expenditures in industrialized countries. Everything used todayhas been machined by grinding at some point in its manufacturing process or has been produced by machines that owe their functionality to grinding operations. Grinding forces play a key role in the grinding process by influencing the specific power consumption, heat generation at the interface of abrasive cutting grains and the workpiece, quality of the ground workpiece surface and various other performance parameters. So, a mathematical model to estimate the grinding forces would help to achieve the target. Previously developed models were usually based on the assumption which might contradict with the reality as they didn’t consider the grain-workpiece interaction at the micro level (i.e., rubbing, ploughing and cutting). Also, most previous studies could only be used to predict average values on wheel basis of grinding forces because the most models were built based on average grain cutting depth or average chip thickness, and none of the grinding force details at the micro level. A new model to predict the grinding forces at micro levelof grain-workpiece interaction have been developed in the present study and validated with help of MATLAB and data available in the previous studies. The effects of grinding parameters such as depth of cut, workpiece speed, wheel speed and size of abrasive grains was studied. The predicted grinding forces were almost identical to the grinding forces experimentally estimated by the previous researchers, with an average percentage error of 6.09%. It was found that the Size of the abrasive grains (abrasive grit number) have the largest impact on rubbing, ploughing and cutting contributions. Depths of cut have the second largest effects and the dominant force component could probably be changed from rubbing to cutting by using different cut depths. The effects of wheel speeds can also be seen: fast wheel speeds lead to less rubbing forces and more cutting forces, while the effects of workpiece feed rates seem to be limited. Therefore, high wheel speeds and large workpiece feed rates are recommended to achieve high material removal rates. (

    Automation of farming equipments based on G/M code for Agriculture 4.0
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-08) Rajwar, Sumit; Rajiv Suman
    Farming is not only an occupation in India but in some cases as the prime source of only livelihood. Any marginal changes in it can cause effects that are positive or negative. Presently India has been able to increase its productivity compared to the Post Independence level. Presently, India is facing many challenges in agriculture from decreasing agriculture land, to increasing population that require increased production, loss of fertility and climate change. All this can cause food insecurity in India as well as push millions back to poverty and malnutrition. This study presents into an insight into the present agriculture in India, and how it is integrated with the economy of the country and how it will affect the people that are directly dependent on agriculture. It gives us the information about the production and productivity of farms. Thus in sync with the agriculture evolution and to facilitate the agriculture 4.0 in India and professes a CNC based mechanism, on G and M code to increase the productivity of agriculture without human interference. So that the people employed in agriculture can be substitute into other occupations, thus reducing the workforce of the agriculture Sector and diversifying them into other sectors. The CNC based machine consists of Machine Control unit, which is connected with the drivers and assembled so that the differential and steering system are run with the help of motors. The Agriculture unit would work on G and M code, which will run the machine along the agriculture field in order to complete agricultural operations. This will reduce farm load as the machine can be used in different agriculture operations such as Sprinkling, Ridging, Transport, weeding, cultivating. Thus it presents a mechanism as well as CNC programme to facilitate agricultural operations. The whole study is to support the Government of India initiative of doubling Farmers Income.

    Parametric investigation and optimization of resistance spot welding of HR E34 SS4012A low alloy steel by using Taguchi methodology
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-08) Rai, Himanshu Krishna; Tewari, Maneesh
    In the present experimental work, HR E34 low alloy steel (SS 4012A) are selected for research work. They are high-quality steels with a combination of alluring qualities that are not possible in common mild steel. SS 4012A material finds application in the construction of ships, railway wagons and carriages, pressure vessels, pipes, heavy duty transport vehicles, etc. Many researchers have worked on RSW to improve the quality of weld joints through modifications to the process and optimization of process parameters. But there was not any work reported on the parametric optimization of the RSW process with low alloy steel, which is slightly different from mild steel. Therefore, in this study, parametric optimization of the RSW process with different process parameters has been undertaken. Welding current, welding time and electrode force were selected as process parameters while tear strength of the weld joint was selected as a response. Experiments were carried out according to Taguchi's L9 orthogonal array (OA) and Taguchi analysis was used in optimization. Analysis of variance (ANOVA) was used to determine the effects of each factor on the quality of the weld joint. The experimental results revealed that the welding current of 15 kA, welding time of 17 cycles, and electrode pressure of 9 bar provided the maximum possible tear strengths of the spot weld joint. The maximum variation in the tear strength of the welded joint was observed by the variation in the welding current.
