Hi Everyone, I want to produce own servo motor using stepper motor because i need full rotational servo motor. This servo will allow clear tracking to my antenna tracker, i want to use it horizontal movement mechanism. For this mechanism we can think it our UAV moves in two dimensional coordinate plane which x-axis and y-axis. If i want to completely track the UAV there shouldn't be any obstacle on my movement as both software and hardware. We can think our movement as a scanning the half sphere, for doing this we need two movement point i want to name it horizontal movement mechanism and vertical movement mechanism. For the full scanning  i can set horizontal movement mechanism to 0-360 degree and vertical movement mechanism 0-90 degrees. Or we can set them both 0-180 degree. In both side we can scan the area clearly. I want to choose first one because in second one there are two critical point if i use. However i want to use it smoothly. At this position i...

     Purpose of the discontinuity of the material and dimensions of the non-destructive testing is to detect it without destroying the material. Sizes and types of discontinuities compared with the standards. Discontinuities in excess of permissible limits that are considered errors, material is sent for repairs or is rejected. In this way, errors are detected clearly and it gives get rid of cost of destructive testing and necessary labor. In daily life people uses transportation vehicles, communication products, home stuffs, hand tools etc. For all these instruments some metallic and non-metallic materials are used. Using for these instruments, materials which are used in them should be tested many times clearly. Wide range of uses these materials directly affect the testing method which is non-destructive testing. Why do you need to non-destructive testing? Prevention of Accidents Improvement of product reliability Determination of the adequacy Prov...
