Research On Numerical Control And Isometry Servo System About Three Coordinate Double Column Cutting Tool

The paper designed a three coordinate numerical control double column cutting tool. It is used to process big or medium-sized flat surface board material or curved surface board material etc . The three coordinate numerical control double column cutting tool can adopt some variety of incise method, for example: the laser incises, the plasma incises, the high pressure water incises etc. Designed and calculated longitudinal feed system, transverse feed system and vertical feed system and checked computations rigid double column framework rigid. Designed numerical control system of the three coordinate double column cutting tool, its hardware system adopted two CPU-the main CPU and the subordinate CPU The main CPU controled the keyboard, display, memory, input or output equipments and so on. But the subordinate CPU used to calculate interpolation and control the isometry servo system, accodingly, the systemic running speed was enhanced obviously. Designed the driving electric circuit and the enlarge electric circuit of step feed motor, the photo-electric insulating circuit, the exceed distance give an alarm electric circuit and the shutting electricity to be protected electric circuit and the isometry servocontrol electric circuit etc. Established a set of system softwares, include the beginning program of the system, the control program to accelerate and decelerate in velocity, the line interpolation program in first quadrant, circular interpolation program in first quadrant, the control program to isometry servo drive, the control program about keyboard and display and some interruption service procedure etCoThe usage of the equipment can greatly improve the quality of products and boost the automatic level of the cutting tool in our country.
