具有限定的弦差和加减速度的插补器

Interpolator With Confined Chord Errors,Acceleration and Deceleration

作者提出了一种数控机床在插补过程中通过调整进给速度从而将弦差限定在一定的误差范围内的插补算法。提出的插补器是一种变进给速度插补器,在保证弦差位于一定误差范围内的同时,增加了数控机床的效率。本文给出了仿真结果以证明该插补器的可行性。

This paper proposes an interpolation algorithm that confines the chord error within a specified tolerance range during the interpolation process by adjusting the feedrate.The proposed interpolator is a variablefeedrate interpolator.Through this variable-feedrate interpolator the efficiency of the machine tool can be increased while keeping the chord error within the specified tolerance range.Simulation results are provided to verify the feasibility of the proposed interpolation algorithm.
