During interpolation preprocess, the high speed adaptive look-ahead control strategy is established by using path transfer point maximum velocity confirming, adaptive predetermination of deceleration point position and stride segment transfer point speed checking. 插补预处理时,按轨迹转接点最高速度确定、减速点位置自适应前瞻确定和整体跨段转接点速度校核三个步骤建立连续微段的高速自适应前瞻控制策略。
