Our CNC machine consist of three axes x, y, z axis for 2-dimensional motion of tool. The numerical data required for working of the plotter is provided by a program called part-program which in turn converts the numerical data to electrical signals. These electrical signals are then given as input to stepper motors. Each signal specifies a specific point in the coordinates and according to the point the toolmove, in our project we are trying to implement simple and efficient 2D plotter.
