对美国国家标准协会（ANSI）、国际标准化组织（ISO）、英国标准学会（BSI）和日本工业标准协会（JIS）规定的机床性能测试标准进行了描述和比较。基于范围和标准差，确定了两种不同的性能测试方法。比较的结果可用于公平评估竞争产品，以及精度改进、误差补偿和并行工程的低成本方法。

MACHINE TOOL PERFORMANCE TESTING STANDARDS, SPECIFIED BY ANSI, ISO, BSI AND JIS, ARE DESCRIBED AND COMPARED. TWO DIFFERENT APPROACHES TO PERFORMANCE TESTING, BASED ON RANGE AND STANDARD DEVIATION, ARE IDENTIFIED. THE RESULTS OF THE COMPARISON CAN BE USED FOR FAIR EVALUATION OF COMPETING PRODUCTS AND LOW COST APPROACHES TO ACCURACY IMPROVEMENT, ERROR COMPENSATION, AND CONCURRENT ENGINEERING.
