ISO 3070-3:2007参考ISO 230-1和ISO 230-2,规定了几何试验、机加工试验和试验,用于检查具有可移动立柱和可移动工作台的通用、正常精度、卧式主轴镗床和铣床的数控定位精度和重复性。ISO 3070?3:2007还规定了与这些试验相对应的适用公差。
ISO 3070-3:2007涉及床身上立柱或立柱鞍座的移动(X轴)、主轴头的垂直移动(Y轴)、镗主轴或冲头的移动(Z轴),以及(可能的)对头(U轴)中径向对向滑块的进给运动-
轴)。一些机器还有一个中间鞍座,在立柱和床身之间有滑道,以实现立柱平行于主轴轴(W轴)的额外移动。
ISO 3070-3:2007仅涉及机器精度的验证。它不适用于机器的运行测试(例如振动、异常噪音、部件的粘滑运动)或机器特性(例如速度、进给),因为此类检查通常在测试精度之前进行。
ISO 3070-3:2007 specifies, with reference to ISO 230-1 and ISO 230-2, geometric tests, machining tests and tests for checking the accuracy and repeatability of positioning by numerical control of general purpose, normal accuracy, horizontal spindle boring and milling machines having a movable column and movable table. ISO 3070?3:2007 also specifies the applicable tolerances corresponding to these tests.
ISO 3070-3:2007 concerns machines having movement of the column or column saddle on the bed (X axis), vertical movement of the spindle head (Y axis), movement of the boring spindle or ram (Z axis) and, possibly, a feed movement of radial facing slide in the facing head (U-axis). Some machines also have an intermediate saddle with slideway between column and bed to achieve additional movement of the column parallel to the spindle axis (W-axis).
ISO 3070-3:2007 deals only with the verification of the accuracy of the machine. It does not apply to the operational testing of the machine (e.g. vibration, abnormal noise, stick-slip motion of components) nor to machine characteristics (e.g. speeds, feeds), as such checks are generally carried out before testing the accuracy.
