Setting up the machine2.6 Measuring the workpiece zeroMillingOperating Manual, 03/2010, 6FC5398-7CP20-1BA0 71Selecting the work offset as basis for the measurementA work offset can be selected as measurement basis to flexibly adapt to the measuringtasks.If the work offset selection as measurement basis is not activated, then the measurementrefers to the currently active work offset.Measuring sequenceTo obtain the desired measuring results, you must keep to the measuring point sequenceshown in the help displays.You can reject measuring points and then measure them again. This is done by pressing thesoftkey that is currently active (measured value).Measuring onlyIf you "only" want to measure the workpiece zero, the measured values are calculated anddisplayed without changing the coordinate system.Work offsetYou usually store the measured workpiece zero in a work offset. The HMI allows rotationsand offsets to be measured.Zero pointThe measurement values for the offsets are stored in the coarse offset and the relevant fineoffsets are deleted. If the zero point is stored in a non-active work offset, an activationwindow is displayed in which you can activate this work offset directly.Machine manufacturerPlease refer to the machine manufacturer's specifications.AligningAlignment can be performed either by rotating the coordinate system or by rotating theworkpiece with a rotary axis. If your machine is equipped with two rotary axes and the"swivel" function is set up, you can also align an inclined plane.Rotary axesIf your machine has rotary axes, you can include these rotary axes in the measurement andsetup procedure. If you store the workpiece zero in a work offset, rotary axis positioning maybe necessary in the following cases.● Correcting the work offset requires you to position the rotary axes to align the workpieceparallel with the coordinate system, e.g. with "Align edge".● Correcting the work offset rotates the workpiece coordinate system, which should alignthe tool perpendicular to the plane, e.g. for "Align plane".
