Research And Application Of Servo Control System In Numerical Control Equipment Modification

The so-called servo control is the effectively aboat control position, velocity andacceleration,etc.Servo control system is widely used in machine tool equipments, it withhigh positioning accuracy, fast response, the advantages of good control performance, haswon the acceptance of machine tool equipment users.On the basis of the servo controlsystem research, established the mathematical model of servo control system, and throughthe simulation, the corresponding control parameters is determined.In the end, choosed thereasonable servo control system, and realized the transformation of the old nc equipment.Main job is to: first, the servo control system is researched and determined the servocontrol system hardware composition, connection;determined the software parameters anddata;Second, through to the analysis and simulation of servo control system workingprinciple, the servo system is studied in detail in the application of numerical controlmachine tool control methods, for the servo system to upgrade the original nc boring andmilling machine to provide the basis.Thirdly, through the original numerical controlequipment system and the analysis of the mechanical part, establish engineered solutions,through the servo system equipment modification, solved the problems of the originalequipment aging, low machining accuracy, frequent failure rate, low production efficiencyand so on.Fourthly,Servo unit established the mathematic model aboat the actuator, andon the basis of the simulation setting the corresponding control parameters.Servo control system of the theoretical analysising and researching, is an importantaspect of nc equipment modification.Through the study and research of servo controlsystem shows that the servo control system has become an indispensable equipmentnumerical control transformation technology,because of its accurate position feedbackfunction and module parameters function.
