To Define the Tool Motion for the Custom Cycle
1. On the top toolbar of the Customize Cycle dialog box, click .
2. Place your pointer in the Cycle Motion box, right-click, and select Add Cycle Point on the shortcut menu.
3. Enter a name for the cycle point. The default name is CPNT<number> where number is the serial number. This number is incremented with each cycle point that you add.
4. Define the initial point along the hole axis by specifying its vertical offset from a certain reference. For example, to start at CLEAR_DIST above the start surface, verify that the arrow in the icon next to the Vertical Offset label is pointing up, select start surface in the from drop-down list and CLEAR_DIST in the By drop-down list.
5. Click .
Creo NC lists the cycle point name, along with the reference and offset, in the Cycle Motion list box, and displays a cyan point in the appropriate location in the graphic window on the right.
6. Add more cycle points to create other GOTO motions:
Use Radial Offset for horizontal motions away from and back to the hole axis. All radial offsets are with respect to the hole axis, you only have to supply the offset value in the By drop-down list.
Use Vertical Offset for vertical motions along the hole axis. You have to supply the reference in the from drop-down list and the offset value in the By drop-down list.
To specify direction, use the following icons:
—Move toward the hole axis.
—Move away from the hole axis.
—Move up the hole axis.
—Move down the hole axis.
To change direction, click the right-pointing arrow next to the icon and select the icon you want.
To specify offset as a mathematical expression, click next to the By drop-down list. The Expression Builder dialog box opens.
Specify the motion type by selecting the Standard, Deep, or Breakchip option.
Creo NC adds the cycle points you specified to the Cycle Motion list box and displays them in the graphic window, with the cycle points shown in cyan and the tool motions between the points shown in white.
7. Select a cycle point from the Cycle Motion list box and click one of the following options in the shortcut menu:
Add Cycle Point—Add a cycle point after the selected point.
Insert Cycle Point—Insert a cycle point before the selected point.
Modify Cycle Point—Modify offset, reference, or direction for the selected cycle point.
Delete Cycle Point—Delete the selected cycle point.
Add CL Command—Add a custom CL command to the selected cycle point.
Modify CL Command—Modify the custom CL command for the selected cycle point.
Delete CL Command—Delete the custom CL command from the selected cycle point.
Add Cycle Modifier—Add a cycle modifier to the selected cycle point. A cycle modifier is an NC parameter. Select the parameter name from the NC Parameter list. Based on the type of NC parameter that you select, Creo NC enables the Select Value or Enter Value box. For parameters with string values, select the parameter value from the Select Value box. For parameters with numeric values, select the expression from the Enter Value box (or define a new expression by clicking ). Click to add the modifier to the selected cycle point.
Delete Cycle Modifier—(Available if you select a previously added cycle modifier.) Delete the current cycle modifier.
8. After you have successfully defined the tool motion, the custom cycle definition is complete. Click at the bottom of the dialog box to add the custom cycle to the workcell and close the dialog box.
