Technical Introduction
The five-axis machine tool is of crucial importance in smart manufacturing. Its positioning accuracy is significantly affected by the geometric error of the rotary table. Based on current measurement capability, the accuracy (specification) of the rotary table made by domestic manufacturers is around ±10" for positioning error (angle) and ±10µm for linear error. This accuracy level lags behind those attained by high end competitors.
The Portable Continuous Angle Standards (PoCAS) NML developed is based on the concept of encoder calibration technology. The measurement error caused by manual installation can be minimized by the proprietary mechanism design and analysis algorithm. PoCAS can be used to measure angular positioning error and linear installation error simultaneously. Its positioning and linear uncertainty are less than 0.8" and 3 µm respectively. By applying PoCAS, the installation and measurement process can be completed within 30 minutes. During production process, PoCAS can help the industry to meet the measurement requirements for assembly and quality control. Overall, it can improve the accuracy of the rotary table for the five-axis machine tool.
