为简化并联机床标定过程，提出了一种新颖有效的模糊插值方法。传统的并联机床标定方法必须使用逆运动学模型或正运动学模型来进行位姿误差的辨识和补偿，这使得标定过程在真实的应用中耗时且效率低下。该方法不使用模型，而是提出了一种与模糊插值方法相结合的无模态技术，以获得高的校准精度时，采用小的工作空间。这种新的方法可以大大减少传统PMT校准过程中的复杂性，大大简化校准程序。
A novel and efficient fuzzy interpolation method is proposed to simplify the calibration process for parallel machine tools (PMTs). Either inverse or forward kinematic models must be used in the traditional PMT calibration methods to perform the identification and compensation of the pose errors for PMTs, which made the calibration process time consuming and inefficient in real applications. Instead of using a model, the proposed method presents a modeless technique combined with the fuzzy interpolation method to obtain high calibration accuracies when a small workspace is adopted. This new approach can significantly reduce the complex in traditional PMT calibration processes and greatly simplify the calibration procedures.
