Setting up the machine2.6 Measuring the workpiece zeroMillingOperating Manual, 03/2010, 6FC5398-7CP20-1BA0 692.6 Measuring the workpiece zero2.6.1 OverviewThe reference point for programming a workpiece is always the workpiece zero. You candetermine the workpiece zero on the following workpiece elements:● Edges, (Page 78)● Corner (Page 80)● Pocket and hole (Page 83)● Spigot (Page 90)Measuring methodsYou can measure the workpiece zero either manually or automatically.Manual measurementTo measure the zero point manually, you need to traverse your tool manually up to theworkpiece. You can use edge probes, sensing probes, or dial gauges with known radii andlengths. You can also use any other tool of which you know the radius and length.The tools used for measuring must not be electronic probes.Automatic measurementFor automatic measurements, only use the electronic workpiece probe, tool type 710. Youmust first calibrate the electronic workpiece probe.In the case of automatic measuring, first position the workpiece probe manually. Afterstarting using the key, the workpiece probe is automatically extended tothe workpiece with the measuring feedrate. Retraction motion from the measuring point isrealized as a function of the setting data with the rapid traverse velocity or a user-specificpositioning velocity.Adapting the user interface to the measurement functionsActivate the following selection options using setting data:● Calibration plane, measurement plane● Work offset as basis for the measuring process● Number of the probe calibration data set● Offset target, adjustable work offset● Offset target, basis reference● Offset target, global basis work offset● Offset target, channel-specific basis work offset
