10、数控机床几何误差及其补偿方法研究 摘要：对数控机床几何误差产生的原因作了比较详细的分析，将系统误差的补偿方法进行了归纳，并在此基础上阐述了各类误差补偿方法的应用场合，为进一步实现机床精度的软升级打下基础。 关键词：数控机床；几何误差；误差补偿 前言 提高机床精度有两种方法。一种是通过提高零件设计、制造和装配的水平来消除可能的误差源，称为误差防止法 (该方法一方面主要受到加工母机精度的制约，另一方面零件质量的提高导致加工成本膨胀，致使该方法的使用受到一定限制。另 一种叫误差补偿法 (通常通过修改机床的加工。

13、1 数控机床润滑系统控制的改进 机床润滑系统的设计、调试和维修保养，对于提高机床加工精度、延长机床使用寿命等都有着十分重要的作用。但是在润滑系统的电气控制方面，仍存在以下问题：一是润滑系统工作状态的监控。数控机床控制系统中一般仅设油箱油面监控，以防供油不足，而对润滑系统易出现的漏油、油路堵塞等现象，不能及时做出反应。二是设置的润滑循环和给油时间单一，容易造成浪费。数控机床在不同的工作状态下，需要的润滑剂量是不一样的，如在机床暂停阶段就比加工阶段所需要的润滑油量要少。针对上述情况，在数控机床电气控制。
