A new Optimum Error Separation Technique (OEST) method is described for in-situ measurement of straightness of a workpiece without an accurate instrument datum, i.e. without a precise guideway. The goal is to alleviate the deficiencies of the traditional sequential-two-point method (STP) and the sequential-three-point method (STRP). These state-of-the-art techniques must use a sampling interval equal to the sensor spacing which has to be larger than the diameter of the sensors. Such a large… CONTINUE READING
