Setting up the machine2.6 Measuring the workpiece zeroMilling84 Operating Manual, 03/2010, 6FC5398-7CP20-1BA0Measuring 3 holesThe workpiece with the three holes to be measured is clamped to the work table in anyposition. 4 points are automatically measured in the three holes and the hole centers arecalculated from them. A circle is placed through the three center points. The center point andthe diameter are determined from this circle. This center point represents the new workpiecezero to be determined. When an angular offset is selected, the base angle of rotation α canalso be determined.Measuring 4 holesThe workpiece with the four holes to be measured is clamped to the work table in anyposition. 4 points are automatically measured in the four holes and the hole centers arecalculated from them. Two hole center points are diagonally connected in each case. Thepoint of intersection is determined from the two lines that are obtained. This point ofintersection represents the new workpiece zero to be determined. When an angular offset isselected, the base angle of rotation α can also be determined.Note"Measuring only" for automatic measuringIf "Measuring only" is selected as offset target, then instead of the "Set WO" softkey, the"Calculate" softkey is displayed.The measuring versions "Rectangular pocket" and "1 hole" are an exception. For thesesingle-point measurements, for "Measuring only" neither the "Set WO" softkey nor the"Calculate" softkey is listed.NoteYou can only measure 2, 3, and 4 holes automatically.PreconditionYou can insert any tool in the spindle for scratching when measuring the workpiece zeromanually.- OR -An electronic workpiece probe is inserted in the spindle and activated when measuring theworkpiece zero automatically.
