In order to calibrate six-component stands, the calibration spaces of two certain calibrating equipment were analyzed and all possible calibration points were classified as force, couple, line vector and wrench firstly. Then, based on implicit second order polynomial, these spaces were optimized by improved D-optimal rule and K-medoids clustering method to form loading schedules. In the end, by comparing the D-opt values, variance inflationfactor （VIF） and leverage values, it was found that all automatically generated loading schedules can minimize the generalized variance of the coefficients under the premise of satisfying the requirement of other indexes. Above theory analysis and method can be applied into other type of calibrating equipment adaptively to improve the calibration precision and efficiency simultaneously.
