Automatic Cutting Machine

In this paper we are concerned about Belt conveyor system not only used in mining industries but also used in cement industries, power plant, food industries, production industries etc. So it is essential instrument for in house material transportation today. The paper presents the review of belt conveyor design modification and latest technologies or working used in different applications to reduce failures, maintenance cost and equipment related fatal accidents occurs during operation. In today’s geopolitical climate, ensuring the protection of secure facilities or key locations against resourceful and determined intruders is of paramount importance to the defense of a national border as well as industries of national importance. The greatest threat to national security is “Terrorism� and it cannot be defeated by conventional military force alone. In critical border areas, regular forces or even satellites cannot monitor. These intruding terrorists as the area monitored is quite large and quite complex. To assist the army and security forces operating in these areas, smart dust like micro-sensors with wireless interfaces could be utilized to study and monitor these environments from a certain distance for military purposes. The spiral bevel gear (SBG) is a key component of the power Transmission of intersection axes. Since the mathematical model of the SBG is a basis for stress and thermal analysis, the optimization of machine-tool settings, frictional contact analysis in lubricated condition, and advanced manufacturing technology, research on designing and manufacturing of SBGs based on mathematical models of SBG has long been a topic of considerable interest in the field of mechanical transmission.
