Power Drive in Robotics 1. Hydraulic drive:-  These systems are generally used in heavy industries for large strength. often these systems can be observed on construction sites, heavy steel plants, etc. Hydraulic drive and electric drive arc the two main types of drives used on more sophisticated robots. Hydraulic drive is g…

Heat Exchanger Heat Exchanger it is at the thermodynamic device in which transfer of heat takes place from one thermodynamic substance to others thermodynamics substance due to presence of temperature difference in an adiabatic system           The design of heat exchanger is based on the point that heat required minimum r…

Surface finish metrology Surface finish is a qualitative parameter and it is qualitify with the help of the roughness parameter. Any machine component will have a certain amount of irregularities which is responsible for appearance on the component. When a component having a large number of irregularities which said to have…

Shrinkage allowance Molten metal supplied inside the mould at high temperature in as it comes in contact with mould wall the solidification process will be initiated. During solidification, the liquid metal first converted into the solid metal and due to change in density of the material it will be subjected to shrinkage.  the…

Heat affected zone The region up to which component is subjected to uncontrolled heat treatment is known as the heat-affected zone.   It is the region or area nearby the weld bead which is subjected to uncontrolled heat treatment heating or cooling.   when high-temperature molten metal deposited in the gap the temperature ne…
