The material flow in the combined extrusion/forging process is an important phenomenon which controls the mechanical and metallurgical properties of any manufactured component. Collet chuck holder is a tool holding device used in different types of CNC milling machines. The chuck holder is described by a flange at the middle to fit into the machine, taper portion which is conical shaped area present at the bottom which enters the spindle for changing holder and collet pocket which fits the collet for holding the cutting tool. For manufacturing the tool holder an enormous amount of material is being wasted by the machining process which is almost equal to the volume of the product. Some manufacturer use casting, subsequently by machining to get the final shape. Both the used processes have their limitations as discussed earlier. To secure our material resources and to get better mechanical properties it is proposed to adopt the combined extrusion/forging and/or multi-stage processes ...

Combined Extrusion-Forging process is a renowned metal forming method which serves as a pathway for manufacturing components of complex design. In that context processing a component with better mechanical and metallurgical properties can be enhanced by severe plastic deformation which processes the fine-grained materials formation in the product. These fine-grained materials achieved by SPD makes the component with superior quality. The novelty of the concept is to validate the presence of fine-grained materials at lower ram displacement. This paper presents the estimated forming load, metal flow pattern and alike, using aluminum 1072 as billet material for manufacturing SCCCH, along with micro-structural validation by experimental die-punch setup and simulation using modelling software DEFORM3D. Numerical analysis was also performed to estimate the forming load and metal flow patterns. Good number of experiments has been carried out at various punch movements to find out forming l...

— It works on principle of moisture measurement, when it subjected to environment the hair like hydroscopic materials absorbs the moisture present in air and contracts, by the contraction of hydroscopic material the mechanical linkage provided reciprocates LVDT transducer such that the linear displacement of soft core of LVDT varies in voltage, this induced voltage is collaborated as readings on digital indicating guage such that water vapour present in the air is measured.

In today's world the rapid growth in automobile industry requested most accurate and high performable vehicles, with pollution free and low cost in operation. The project free powered electric vehicle is an automobile which works on the principle of generating electricity with the help of synchronous electric motor and generator with attached fly wheel, boosting circuit which acts as a free powering machine by restoring waste mechanical energy into useful electric work. This device consists of one electric motor and generator with attached fly wheel in centre so that it connected with motor and generator with belt pulleys. When an mechanical input is given to the generator with help of stator its produces electricity later which is passed to motor as input so, motor rotates the attached flywheel then the stored kinetic energy in the flywheel is utilized to multiply the rotations of generator shaft to produce electricity with little effort on motor in this way cycle repeated and from produced electricity some amount of electricity taken as output which is used for charging batteries, accessories of the electric vehicle. Such that vehicle is propelled.
