Example: Creating a Custom Holemaking NC Sequence
In this example, you are going to create a Holemaking NC sequence using the custom cycle called FDRILL. Creating this custom cycle is described in a previous example topic (follow the topic under Related Links for details).
1. Click Custom on the Mill or Turn tab. The Custom Drilling tab opens.
2. Select a tool from the tool list box, or click Edit Tools.
3. In the list next to , select a cycle or the Edit Cycles option. The Customize Cycle dialog box opens.
4. On the top toolbar of the Customize Cycle dialog box, click , select FDRILL in the Existing Cycles list box, click the right mouse button, and click the Select cycle and return option on the pop-up menu.
Close the Customize Cycle dialog box.
5. Click to specify parameters specific to holemaking.
6. On the References tab, choose a method for specifying the holes to be drilled. Click Details to open the Holes dialog box.
7. Use any selection method to specify the holes to be drilled. For example, click Rule: diameters and select the hole diameter corresponding to the cutter diameter of the tool. Close the Holes dialog box.
8. On the References tab, the Cycle References box lists all the references and variables used in the cycle definition. The parameter values are also listed. The default drilling depth option is Auto, which means that the start surface and the end surface are determined automatically. You have to assign a value to the feed surface reference and to the new feed variable.
9. Select feed surface in the Cycle References box. Select from the list below Cycle References and type -2 as the Z offset value. This means that the feed surface is 2 inches below the XY-plane of the NC sequence coordinate system, which in our example coincides with the start surface (see the following illustration).
10. Select new feed in the Cycle References box. Select from the list below Cycle References and type 30.
The NC sequence tool path is shown in the following illustration:
11. Click to complete the cycle placement and close the tab.
