Currently, the use of work holding devices such as clamps greatly affects the productivity and economy of a large number of processed workpieces. This device reduces the production cost and ensures interchangeability of machined work pieces. In fixture design for the manufacturing of part, there are various challenges and serious problems in industry. Precision is one of the most important issues in the machining process and main cause for rejection is the part static deformation and dynamic vibration. And also hectic to worker for job mounting, and perpendicular error of drill with vertical axis, which influence the efficiency and quality of fixture design. For accuracy of drill at specific point the job is to be fixed properly. In order to mount job accurately hydraulic clamps are used which results in perpendicular accuracy of drill with vertical axis is up to 20 microns. Keywords-Interchange Ability, Static Deformation, Dynamic Vibrations, Accuracy

When coconuts are required in large numbers say 150 to 180 nuts per hour, manual dehusking becomes tedious and labour cost increases steeply. So the process needs to be mechanized. So this paper describes about process of operation and working principle. The shearing blades on roller are attached over cylindrical rollers through its length. When blades rotate, at a high torque, coconut is pricked by blades and due to inertia of both blades rotating in opposite direction coconut cannot rotate along with both the blades simultaneously, Hence coconut is sheared apart at blade and husk intersection. This process carries on till entire coconut is completely dehusked. This machine is economically far better than manual method in terms of per unit basis. Also overall costs will become lesser in long run for mass dehusking for which this machine is intended to do. Each key part of the model was individually analyzed in Ansys for forces acting on that individual part. In our model key parts were Frame, Roller and Gear. A standard procedure was followed for analysis of all parts. The detailed step is described in Analysis chapter. This model was analyzed in ANSYS Version 16. Modeled machine is exact in dimensions with actual machine. Modeling was done in Solid works 2015.
当需要大量的椰子时，比如每小时需要150到180个椰子，人工去壳变得乏味，劳动力成本急剧上升。所以这个过程需要机械化。因此本文介绍了该装置的工作过程和工作原理。滚筒上的剪切刀片通过其长度连接在圆柱形滚筒上。当叶片旋转时，在高扭矩下，椰子被叶片刺穿，由于两个叶片旋转方向相反的惯性，椰子不能同时随着两个叶片旋转，因此椰子在叶片和外壳相交处被剪开。这个过程一直持续到整个椰子完全脱壳。按单位计算，这台机器比人工方法经济得多。此外，从长远来看，总体成本将变得更低，这台机器将用于大规模脱壳。在Ansys中对模型的每个关键部分分别进行了受力分析。在我们的模型的关键部件是框架，滚轮和齿轮。所有零件的分析都遵循标准程序。具体步骤见分析一章。在ANSYS Version 16中对该模型进行分析。模型机的尺寸与实际机的尺寸完全一致。建模在Solid works 2015中完成。
