Notes:
The marriage of computer, electronic technology and traditional machining disciplineshas given birth to revolutionary new disciplines, Mechatronics. Therefore Mechatronics requiresmechanical, electronic and computer knowledge together. The main aim of this article is to presentthe mechatronics approach for desk-top CNC milling machine design. Construction of computercontrolled (CNC) Machine differs greatly from that of conventional machine tools. This differencearises from the requirement of higher performance levels. Machine Structure, guide ways, feeddrives, spindle and spindle bearings, measuring systems, machine control unit, software andoperator interface, gauging and tool monitoring should be considered as mechatronics approach.Servo motors, motor drivers and motor control unit were used in this CNC milling machine to makeit flexible and easy programming. Ball screws were used to X-Y –Z axes to eliminate backlash ofthe slides. Non-contact home and Limit switches were used to prevent possible damages againstover travels. Necessary torque and power have been calculated to select the motors by taking careof the load, ball screws, motor inertia and required cutting tools and etc. and developed CNCmilling machine has been tested several times for reliable machining of machine parts
