从实用角度介绍了应用宏程序在加工中心刀具长度补偿中自动输入刀具长度补偿值的方法。此方法不仅省略了手工对刀操作中手工记录、计算和输入补偿值等过程,而且避免了在上述过程中可能发生的错误,提高了生产效率。试用结果表明:该方法可靠、方便,缩短了机床辅助工作时间,提高了加工精度和机床生产效率,具有很强的实用价值。 A practical way of applying the macro program to automatically input the tool length compensation value in the machining center tool length compensation is introduced. This method not only omits the process of manual recording, calculating and inputting the compensation value in the manual tool setting operation, but also avoids the errors that may occur in the above process and improves the production efficiency. The trial results show that this method is reliable and convenient, shortens the auxiliary working time of machine tool, improves the machining accuracy and the machine tool production efficiency, and has strong practical value.
