Data of setpoints and linear encoder of moon-shaped trajectory

\tThe basic task of multi-axis CNC machine tools is trajectory control. Due to the existence of Dynamic Error Outside Servo-loop (DEOS), the Linear Encoder Feedback Position (LEFP) under closed-loop control is inconsistent with the Effector End Position (EEP), which results in the difference between the trajectory at the LEFP and the trajectory at the EEP.  \tThis dataset includes: Setpoints Positions (SP), setpoints acceleration, and setpoints jerk of X- and Y-axis; Linear Encoder Feedback Positions (LEFPs) of X- and Y-axis; Effector End Positions (EEP) of X- and Y-axis; Curvature of the moon-shaped trajectory; Trajectory error at LEFP; Trajectory error at EEP. These data represent the Influence of DEOS on the trajectory error\t \tThe SPs were generated and collected the KEDE GNC61 CNC system. The programmed feed rate is set to 10000mm/min. The LEFPs and EEPs were calculated by the transfer functions from SP to LEFP and the transfer functions from SP to EEP of a machine tool, respectively. While, the trajectory errors at LEFP and at EEP are solved according to the geometric relationship.\t \tThe time interval of these data is 2ms.

多轴数控机床的基本任务为轨迹控制。由于伺服回路之外的动态误差（DEOS）的存在，闭环控制下的线性编码器反馈位置（LEFP）与执行器末端位置（EEP）之间存在不一致，导致LEFP处的轨迹与EEP处的轨迹之间存在差异。本数据集包括：X轴和Y轴的设定点位置（SP）、设定点加速度和设定点加加速度；X轴和Y轴的线性编码器反馈位置（LEFPs）；X轴和Y轴的执行器末端位置（EEP）；月牙形轨迹的曲率；LEFP处的轨迹误差；EEP处的轨迹误差。这些数据代表了DEOS对轨迹误差的影响。设定点（SPs）由KEDE GNC61数控系统生成并收集，编程进给速率设定为10000mm/min。LEFPs和EEPs分别通过机器工具的SP至LEFP和SP至EEP的传递函数进行计算。而LEFP和EEP处的轨迹误差则是根据几何关系求解的。这些数据的时间间隔为2ms。
