ABSTRACT:
Scanners are useful for scanning an object, to detect the flaws and plotting it. Previously, the object under test was scanned and was plotted manually which consumed a lot of time. Manually, scanning an object at each and every point and plotting it accurately is very difficult. By using 2D-scanning and plotting mechanism, we can detect or inspect the flaws easily without human interference. Assembly language programming is used to perform some of the system operations. In this system, inductive type proximity sensors are used. These sensors sense the dimensions and the surface voids of the object accurately.
This system consists of PC, two stepper motors, a microcontroller, a proximity sensor and a scanning frame. The main operation of this system is that the two stepper motors, arranged in two directions (X-Y), are connected to the PC through the microcontroller. The scanning is done line by line according to the user instructions given by the PC and that scanned object is plotted accurately on the monitor through the proximity sensor.
This system finds its applications to inspect the voids and flaws on the surface of the object under test without taking much time. The project is based on the assembly language program to run the microcontroller.
