摘　　要：螺距误差是衡量数控机床性能的一项重要指标,螺距误差的检测及补偿更是数控机床调试和维修的主要内容。本文主要讲述了基于雷尼绍XL-80型激光干涉仪进行线性测量的原理及过程,并通过实际对VB-825A型加工中心的检测来分析FANUC系统螺距补偿的方法及过程,同时通过测试结果对比来说明螺距误差补偿对机床精度的影响。Pitch error is an important indicator for measuring performance of CNC machine tool, detection and compensation of pitcherror is the main content for debugging and maintaining of CNC machine tool. This article mainly describes the principle and process oflinear measurement using Renishaw XL-80 laser interferometer, and through the actual detection of VB-825A machining center to analyzethe method and process of pitch compensation of FANUC system, at the same time through the test results contrast to illustrate the pitcherror compensation on the impact of machine accuracy.
