Paper Title:
Research on the Velocity Look-Ahead Algorithm in the NC System
  Abstract

Aiming at improving the interpolation efficiency without lowering the machining accuracy, the velocity look-ahead algorithm in the numerical control (NC) system is introduced. Firstly, the machining path’s transferring vector angle model is established, and then the conditions of direct transfer for the adjacent paths are also discussed. Secondly, based on the linear acceleration/deceleration control, the velocity look-ahead algorithm is put forward which can find the approximate-optimal velocity adaptively according to the maximum number of the look-ahead blocks and the geometric properties of the machining path. Finally, the acceleration/deceleration control in the consecutive micro-path can be realized, therefore, the high-speed and smooth transfer of feed-speed among machining path blocks can be achieved.
