To Create a Rest Finishing NC Sequence

1. Ensure that the active operation references a Mill or Mill/Turn work center.

2. Click Mill > Milling >

Rest Finish. The Rest Finish tab opens.

You can also create or edit a step from the Process Manager. For details, see To Insert a Milling Step.

3. Select

, or

for milling on Head 1, Head 2, Head 3, or Head 4.

The Head Selector options are available only if the operation references a Mill-Turn or Lathe, and if both heads are activated in the work center.

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. Select a tool only of type BALL MILL or TAPER BALL MILL.

To show tools for the current step and the active head on the machine tool, set the INCLUDE_ALL_TOOLS_IN_LIST option to YES.

Alternatively, right-click in the graphics window and select Tools.

5. To preview the cutting tool and its orientation in the graphics window, click

Preview to the right of the tool list box. The

Previewbutton 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, or click

Preview again.

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 commands:

◦ 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:

◦ Reference Cutting Tool—Select a ball mill as a reference tool to determine the area to be machined.

◦ Mill Window—Select a Mill Window as the reference. Reference Model surfaces that lie inside the mill window are machined.

Alternatively, right-click the graphics window and select Mill Window 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 rest finishing. By default, the required parameters are defined by relations that you can modify from the Relations dialog box.

Alternatively, right-click the graphics window and select Parameters from the shortcut menu.

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.

11. Click

to get a dynamic preview of the tool path in the graphics window.

12. On the Process tab, optionally use any of the following options for the machining step:

◦ Calculated Time—Click

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

◦ Prerequisites—Click

. The Select Step dialog box opens. Select an existing step that is a prerequisite for the new step. Click OK.

The Prerequisites option is available on the Process tab while creating or editing a step from the Process Manager.

13. 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.

▪

—Insert the contents of an existing text file of step comments at the cursor location. Preserve any current step comments

▪

—Save current step comments in a text file.

▪

—Accept the current step comments.

14. After you define the mandatory step elements, the following buttons become available:

◦ To play the tool path, click

◦ To perform gouge checking against surfaces of the reference part, click

◦ To view the simulation of material removal as the tool is cutting the workpiece, click

. The Material Removal tab with integrated simulation environment opens.

15. Select one of the following options to complete the sequence:

◦ Click

to save the changes.

◦ Click

to pause the process and use one of the asynchronous tools. Click

to resume.
