Study on Structural Optimization and Servo Control for All-Electric CNC Broaching Machine

Abstract:

With respect to the conventional hydraulic broaching machine, the all-electric CNC broaching machine has many advantages. This paper combines the digital servo control system, the double ball screw and the linear motion rail to realize broaching for the two workpieces internal threads of the different rotations and lead distances. The DSP-based full-AC drive control system was developed. The observer is used to observe the speed instead of measuring the speed using the velocity sensor such as the encoder. It solves the drive control problems for the speed-sensorless servo-motors. That is in line with the trend of the CNC broaching machine technology toward the electronization, high-speed and preciseness.
