To Create a Chamfer Milling NC Sequence

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

2. Click Mill >

Chamfer Milling.

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

3. To select a tool or change tool parameters, open the Tools Setup dialog box in one of the following ways:

◦ Select a tool type CHAMFERING, DRILLING, or COUNTERSINK from the tool list box, or click

Edit Tools in the list box. The tool list box only includes tools that are valid for the step. You can also use a solid tool with the appropriate geometry required for chamfer milling.

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.

◦ Right-click the graphics window and select Tools from the shortcut menu.

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

to the right of the tool list box. 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.

5. 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.

◦ Machining References—Select chamfered surfaces as machining references.

◦ Cut Type—Select Climb or Upcut to define where material is relative to the tool rotation.

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

7. 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 chamfer milling. 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.

8. 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.

9. 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.

10. On the Tool Motions tab, select the options 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.

With the Return to Step Options option on the shortcut menu in the graphics window you can switch from editing tool motions and editing step references. This option is available only when all references for tool path computation are successfully defined.

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.
