ActiveTest code for machine tools—Part 4: Circular tests for numerically controlled machine tools
机床检验通则 第4部分：数控机床的圆检验
Application Summary AI generated
This standard specifies methods for testing the circular interpolation accuracy of numerically controlled (NC) machine tools, such as CNC milling machines and machining centers. It is applied during machine tool acceptance, performance verification, and periodic calibration to evaluate contouring errors, backlash, and servo mismatch. The circular test helps manufacturers and users ensure precision in producing circular or curved workpiece geometries.
