提出了一种估算棱镜零件高速铣削加工时间的方法。机床加速度和刀具轨迹几何是决定高进给速度下加工时间的主要因素。使用机加工测试零件测量机床加速度以及刀具路径方向变化对实际进给速度的影响。开发并校准了一个简单的加工时间估算数学模型。实验验证表明，对于进给速度高达16 m/min的铣削操作，加工时间可以估计在实际时间的3%以内。

A methodology was developed to estimate the machining time in high speed milling operations of prismatic parts. The machine tool acceleration rate and the tool path geometry are the main factors that determine the machining time at high feed rates. Machined test parts were used to measure the machine tool acceleration rate and the influence of changes in tool path direction on the actual feed rate. A simple mathematical model to estimate machining time was developed and calibrated. Experimental verification showed that machining time could be estimated within 3% of the actual time, for milling operations at feed rates up to 16 m/min.
