4. Click 
Tool Manager or select 
Edit Tools from the tool list box to open the Tools Setup dialog box and add a new cutting tool or change tool parameters. The tool list only includes tools that are valid for the step.

The button becomes available once a tool is selected.Alternatively, right-click the graphics window and select the Tool Preview option on the shortcut menu. After you select a tool, the Tool Preview option is available on the shortcut menu of the graphics window.
To exit the tool preview, right-click the graphics window and select Cancel tool preview from the shortcut menu.
6. To change the coordinate system that defines the orientation of the step, click the collector adjacent to 
and select a coordinate system. If the operation coordinate system differs from the step coordinate system, right-click the collector for the following options:
and select a coordinate system. If the operation coordinate system differs from the step coordinate system, right-click the collector for the following options:◦ Default—Replaces the selected coordinate system with the default reference. The default is the orientation that is copied from the previous step or from the operation.
◦ Information—Displays the information of the selected coordinate system.
| | After you specify a coordinate system for an NC sequence, it remains in effect until you change it. |
Alternatively, right-click the graphics window and select Orientation from the shortcut menu.
7. Select the following options on the References tab
:
◦ Machining Reference—Select a Mill Window from the graphics area or Model Tree. All the surfaces within the specified mill window are machined.
To create a new mill window, click 
Geometry > Mill Window on the Finishing tab. The Window tab opens. For details on creating a Mill Window, see Related Links.
Geometry > Mill Window on the Finishing tab. The Window tab opens. For details on creating a Mill Window, see Related Links.◦ Excluded Surfaces—Select surfaces that lie inside the mill window that you want ignored while machining.
◦ Loops To Close—Select open loops on surfaces that need to be closed. Ensure that the surfaces lie inside the mill window.
◦ Surface Side— Specify which side of the surfaces you want to machine. This option appears only for models with quilt geometry, such as imported models where the material side is not defined. By default, the system selects a side to machine. Use this option to check which side is selected or to change the side.
Alternatively, right-click the graphics window and select Excluded Surfaces, Machining Reference, and Close Loops from the shortcut menu.
8. On the Parameters tab, specify the required manufacturing parameters.
You can also click 
to copy parameters from an earlier step or click 
to edit parameters specific to Finishing. By default, the required parameters are defined by relations that you can modify from the Relations dialog box.

9. On the Clearance tab, optionally specify the following:
◦ Retract—Specify the Type, Reference, Orientation, and Value for the retract definition
◦ Start and End Points—Specify the Start point and End Point for the step tool path.
Alternatively, right-click the graphics window and select Retract. You can also select the Start Point and End Point of the cutting tool from the shortcut menu.
10. On the Options tab, open a part or assembly to use as a cutting tool adapter. Alternatively, click to copy cutting tool adapter from another step.
to copy cutting tool adapter from another step.11. Select options on the Tool Motions tab to create, modify, and delete tool motions and CL commands for defining cut motions. For details on all the tool motions, see the topics under Related Links.
Alternatively, right-click the graphics window and select Tool Motion Options.
| | The Return to Step Options option on the shortcut menu in the graphics window enables you to switch from editing tool motions and editing step reverences. This option is available only when all references for tool path computation are successfully defined. |
12. Click

◦ Calculated Time—Click 
to automatically calculate the machining time for the step. The Calculated Time box shows the time.

14. On the Properties tab, optionally specify the name or comments for the step.
◦ Name—Displays the name of the step. You can type another name.
◦ Comments—Type the comments associated with the step in the text box or use the following options:
▪ 
—Read in an existing text file containing step comments and replace any current step comments.
—Read in an existing text file containing step comments and replace any current step comments.▪ 
—Insert the contents of an existing text file of step comments at the cursor location. Preserve any current step comments
