DESIGN AND PROTOTYPE OF CNC VERTICAL MACHINING COUNTER WITH THREE AXIS SERVO MOTOR CONTROL
AbstractOn the basis of vocational and technical education, applied learning and computer assisted manufacturing courses are being taught in many vocational education institutions by means of theoretical and simulation methods on the basis of laboratories and inadequacy of infrastructure and still on board and computer. The main purpose of this study is to develop the CNC vertical machining center in technical specifications that can be used as training material in workshops and laboratories with their own possibilities of vocational and technical education institutions. A lot of work has been done in this regard, but the developed machines are seen as desktops, usually with weak body and stepped motors with limited power, with limited parts that they can process and with low processing speeds and inadequate machines. In the scope of this study, it is aimed to develop and prototype three axis vertical machining center with servo motor control which can be processed not only in wood and plastic materials but also in metal and steel materials. In accordance with this purpose; A CNC workbench which can cover a small area but can also function as an industrial type CNC, servo motor controlled, air and liquid cooled, steel, and other hard materials can be designed and manufactured. Preliminary examinations made and material of the main body and axis parts in the direction of the works have been selected. As a result, 3 axis CNC designed and manufactured with servo and motor control with 750x500x150 mm (X, Y, Z) machining area and air cooled with alcohol have been successfully manufactured. Aluminum and various composite materials, especially steel, are processed without problems. The theoretical precision and standard deviation of the loom are calculated. The study was supported by the project number GDK2017-BA007 by İstanbul Gedik University Scientific Research Projects Coordination Unit.
