When machining a series of short linear segments, the computer numerical control system interpolates the machining path with the pre-specified spline curve to obtain continuous feed motion. However, to obtain adequate smooth tool-paths to smooth the feed velocity and acceleration, the computer-aided manufacturing system needs to use a higher order spline curve, which will be limited by some technical bottlenecks. In this article, a new real-time interpolation algorithm is proposed from the perspective of kinematics to achieve uninterrupted feed motion throughout the global tool-path. At the same time, the acceleration profile achieves G2 continuous to avoid unnecessary feed frustration and inertial impact, reaching the balance between time-optimal and motion performance. First, the jounce-limited acceleration curve is blended at the corner of the machining path, and the optimal cornering transition velocity is obtained by adding the velocity, acceleration and contour error constraints to the corner transition motion. Then, according to the linear segments with different lengths between the corners, combined with the feed motion around the corner, a look-ahead interpolation algorithm is proposed to calculate the maximum feed rate with the constraint of the linear segment length and kinematic boundary conditions. At last, for the linear segments whose corner contours overlap with each other after interpolation, the smooth transition between the two corners can be realized by mixing the feed motion of the next corner. Compared with non-uniform rational B-spline interpolation algorithm, the proposed algorithm reduces the total machining time by 14% and the computer numerical control system improves the computational efficiency by 11%. It proves that the proposed algorithm has better application value in the manufacturing of complex parts.

Point-by-point comparison interpolation algorithm is often applied to NC （Numerical Control）system, however，there are some problems such as lag in phase, out of step and low-speed crawl for higher feed velocity（ ≥3000mm/min）in multi-axes synchronous machining system, which influences response velocity and interpolation precision of NC system. In view of this， based on the point-by-point comparison principle , the midpoint interpolation algorithm for deviation judgment in NC machining trace control was proposed, mathmatical model of interpolation established, the deviation judgement function of the interpolation algorithm improved and optimized. It is shown from comparative analysis and practical application of midpoint interpolation algorithm that the interpolation precision raises from 1 to 0.5 pulse equivalent, interpolation points reduce greatly, response velocity quickens and interpolation precision heightens as well.
