为了进一步提升数控机床的加工精度和一致性，华中数控计划与机床企业充分合作，实施“机床品质提升工程”计划，将华中8型智能数控系统热误差补偿技术应用于数控机床，致力于提高机床加工效率、加工精度和加工一致性，提升机床品质和市场竞争力。
随着科学技术、机械制造加工业的迅速发展，对数控机床的加工精度提出越来越高的要求。提高数控机床加工精度有两种基本方法：误差防止法和误差补偿法。误差防止法是指通过提高机床制造和装配精度及设计精度、机床零部件的制造精度和安装精度、优化机床结构、辅助部件等方法来实现。此方法的特点是成本增加大，实施起来有局限性。误差补偿法是指使用软件技术，通过分析、统计、归纳及掌握原始误差的特点和规律，建立误差数学模型，进行人为误差补偿，从而减少加工误差。此方法的特点是：经济有效，实现相对简单。
已故的国际著名机械制造专家、美国密西根大学教授吴贤铭曾说过：“误差补偿技术的巧妙之处在于加工出的零件精度可比加工母机的精度还高。”由此可见，误差补偿技术的巨大作用。
目前，误差补偿技术以其强大的技术生命力迅速被各国学者、专家所认识，并使之得以迅速发展和推广，已成为现代精密工程的重要技术支柱之一。
热误差补偿技术有哪几种？
热误差补偿技术主要分为热误差斜率补偿和热误差偏置补偿两种方式：
热误差偏置补偿又叫与位置无关的热误差补偿，是在热变形部件上安装温度传感器，检测传感器的实时温度，通过查询补偿表中对应温度的补偿值，将目标轴的机床坐标系进行偏移。用以消除该部件因热变形导致的轴向热位移，一般用于非移动部件，如主轴、动力头等发热量较大且易产生结构变形的部件上。
热误差斜率补偿又叫与位置相关的热误差补偿，在传动部件（丝杠、齿轮齿条）上安装温度传感器，测量出传动部件极限温度区间内所有温度点对应的目标点热变形量，通过统计和计算合理安排温度补偿间隔，将计算出的热误差补偿数据填入补偿表中。系统通过检测温度传感器的实时温度，查询补偿表中对应温度的补偿值，根据目标轴的实际位置相对于热膨胀零点的距离折算出补偿量输出到目标轴上。用以消除传动部件当前所在位置相对于热膨胀零点的热伸长量。
数控机床的主要误差来源有哪些？
数控机床产生误差的来源主要有：几何误差/运动误差、热误差、控制误差、力误差等，通过研究发现，所有的误差来源中热误差占比最高，达到近40%。
