Design and application of a computer controlled vertical milling machine

In this thesis study, an old CNC vertical milling machine have been modernized into a twoaxis milling machine, with the addition of two servo motors. A servo-motor control unitcalled Siemens Simotion D425, two CUA31 servo power amplifier units that connected tothe control unit and two servo motors have been used in this project. To make this unitwork as a vertical milling machine, basic movement functions have been defined inStructured Text language, which is one of the supported languages of the motor controllersoftware called Siemens Scout. A Visual Basic software has been developed to convert Gcode styled shape commands to Structured Text programs which call the defined basicmovement functions. When executed in Siemens Scout, these generated Structured Textprograms operate the desired shapes.
