Interpolation of continuous micro line segment trajectories based on look-ahead algorithm in high-speed machining.

Published in International Journal of Advanced Manufacturing Technology, 2008

In this paper, an interpolation method based on look-ahead algorithm is presented. With the proposed method, CNC systems can predict the variation of the curvature of the coming trajectory so that adaptively determine whether accelerates the interpolation feedrate to enhance machining efficiency or decelerates the feedrate to guarantee the machining precision.

Improvement of the evaluation of closed-loop production systems with unreliable machines and finite buffers

Published in Computers & Industrial Engineering, 2014

This paper presents two modifications that improve the algorithm of Gershwin and Werner (2007) for closed-loop systems. Two new special types of two-machine one-buffer building blocks are developed for the decomposition, and analytical solutions for them are found.
