To Create GoTo Point Motions
GoTo Point motions enable the probe to go to a Measured or Constructed point, or to any datum point. You can restrict moves along some of the axes of the reference coordinate system.
1. Choose GoTo Point from the drop-down list in the Customize dialog box, and click Insert. The Goto Point dialog box opens.
2. Click Specify Point to create or select the control point. The CR/SEL POINT menu appears with the options:
Select—Select a Measured or Constructed point, or an existing datum point.
Create—Create a new datum point using the regular functionality for creating datum points. The datum point will belong to the CMM assembly.
3. The Specify Offset button allows you to specify a target point offset from the control point created using the Specify Point button, described above.
4. The next portion of the dialog box allows you to restrict moves along some of the axes of the NC Sequence coordinate system:
If the Simultaneous option button is selected, then, depending on whether the X axis, Y axis, or Z axis checkbox is selected or cleared, the probe is allowed or disallowed to move along this axis. By default, all the axes are allowed; the probe then moves directly from the current position to the target point. If some of the axes are disallowed, the final probe position is computed based on the current point and the axes allowed.
If the Z First option button is selected, the probe moves along the Z-axis from the current position to the level of target point; it then moves using the X- andY-axes to the target point.
If the Z Last option button is selected, the probe moves in the XY plane, from the current position to the location of the selected point, and then moves along the Z-axis to arrive at selected point.
5. The Preview button allows you to preview the probe motion defined. Click OK if satisfied, or Cancel to quit creating the probe motion.
