A Process of improving the strength and resistance to water absorption of Wood Hardboard along with a lessening in the number of conventional steps is disclosed. Hardboard is thereby produced with dry leaves fallen from the trees in residential or forest area can be collected by village people or rag pickers and then this collected waste to be crushed in a Grinder or crusher and mixed in Mixer to make the powder. The above Mixture is used to make, Chip Boards and other Wooden Products like Door Frames, Panels, Frames etc., using the Press by adding polymer to the powder. Here we learnt about how to use the forest wastes for useful purpose to clean the environment and most importantly to save the forest.

Welding is a process in which localized coalescence (permanent joint) is produced by heating the material up to suitable temperature with or without application of filler material. Normal arc welding is performed in an open atmosphere and effect of the wind velocity , on the weld is neglected. So in this study, experiment is conducted to find the effect on weld strength, using arc welding with varying wind velocity. Welding was performed at wind velocity, varying from (0-20) Kmph and welding parameters are kept constant. To find out the Weld strength, tensile test and Impact loading test is performed and Dye penetration test is performed to find out the surface defects.

TIG welding is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. Fixing of the input parameters plays a significant role in getting the quality weld joint. Generally, all welding processes are used with the aim of obtaining a welded joint with the desired mechanical properties with minimum distortion.The present study is to investigate some aspects of TIG welding. In this study of non destructive testing and tensile test of weldments have been carried out on a aluminum alloy 65032 and stainless steel alloy AISI 321 using GTAW with non pulsed different currents. The radiography, liquid penetrant test and tensile test have been carried out on the weldments of the above two materials having thicknesses (i.e., aluminum alloy 65032 of 3mm an stainless steel alloy AISI 321 of 2.4 mm). The aim of this study is to compare the various characteristics of weldments at different currents levels. The experimental results examine different welding parameters for aluminium alloy 65032 and stainless steel AISI 321) using non pulsed currents GTAW.

Wire-cut electrical discharge machining is one of non conventional manufacturing processes for maching hard to machine materials and intricate shapes which are not possible with conventional machining methods. This paper presents the effect of various WEDM process parameters such as wire speed, wire tension on different process response parameters such as material removal rate (MMR), surface roughness (Ra), wire wear ratio (WWR). This paper also reviews optimization methods applied by researchers and finally outlines the recommendations and future trends in WEDM research.

Agriculture is very important for Indian economy. India being developing nation, the technology in agricultural sector has importance to improve productivity in this sector. The Rotary Tiller is a useful machine in farm land cleaning after cutting crops having very close distance between the plants like vegetable crops, cotton, cultivation of paddy etc. A Rotary tiller is a type of motorized cultivating equipment that breaks the soil with the help of rotary blades. It is used for removing weeds (waste plants) in agricultural land before and after planting seeds. The present SOLAR TILLER project is developed by the integrating of the Electric Hub motor to rotate blades and motor is powered by solar photo voltaic cells and allows farmers to do farming with less efforts and at almost zero running and maintenance costs with no pollution.

Vacuum forming machine is a simple way of thermoforming, where a plastic sheet is heated to forming temperature, stretched on to a single surface mould and forced against the mould by a vacuum. This forming process can be used to form plastic into permanent products such as casings and protective covers. Normally draft angles are given during design of the mould at least about 3 degrees for easy removal of formed plastic part from the mould. Parts having high depth can be formed if the formable sheet is mechanically and pneumatically stretched prior to bringing it into contact with the mould surface and applying vacuum. There are few types of forming machines. Such as vacuum forming, pressure forming and twin sheet forming. There are different types of plastic sheets which can be moulded; they are ABS Thermoform plastic sheets, PETG Thermoform plastic sheets and Polycarbonate / lexan thermoform plastic sheets. Materials used in vacuum forming are generally thermoplastics. The commonly and easiest to use thermoplastic is high impact polystyrene sheeting (HIPS). This is moulded around a wood, structural foam or cast or machined aluminium mould, and can form to almost any shape.
