Lathe Features Overview
Introduction
This topic will introduce Turning Features, how to create them, and how to work with existing features. This topic will also provide links to related topics.
Turning Features
Lathe Features can be thought of as simply as you would the features
of the final product itself. For any feature of the part itself, work
will have to be done to create it. Any work you choose to do on a feature
will be an operation that you add. To create a feature, right-click on
the Machine Setup and choose between Lathe End Face, Lathe Turning, Lathe
Groove, Lathe Hole, Lathe Tap Hole, Lathe Thread, Lathe Cutoff, and Lathe
Stock Handling. Once the feature is chosen and the Lathe Wizard is launched,
you will be able to select any number of operations needed to complete
the chosen feature.
When you create a lathe feature and finish the feature wizard, the feature
is added to the Lathe Job in the CAM Tree. All of the information from
the wizard can be viewed or modified using the feature in the CAM Tree.
Each item of the feature contains a shortcut menu for you to access various
functions and commands.
Introduction
The Lathe Wizard contains multiple
dialog boxes arranged to lead you through defining your Turning features.
This includes selecting feature geometry, defining the feature-level
parameters, and then defining the operation-level parameters. When
you add a Turning feature in the CAM Tree, the Lathe Wizard
displays. The setup process, navigation, and all parameters are explained
in the Lathe Wizard help topics.
Navigation
To create a Turning feature:
- In the CAM
Tree, right-click Machine Setup, and select
a Lathe feature type in the context menu.
The Lathe Wizard displays.
The Lathe Wizard Overview
-
Add a Lathe feature based on the target geometry.
-
In the first page of the wizard, you assign the
feature geometry.
Note: After finishing the wizard, any changes to the feature geometry
are made using the CAM Tree. The geometry item in the wizard is
not available when editing a feature.
-
In the second page of the wizard, you define the
feature parameters.
The settings you define here are applied to all operations in the
feature.
-
In the third page of the wizard, the Machining
Strategy, select a Template for the feature.
Modify the Current Operations to contain the desired number and
order of operations for the feature.
Note: When editing a feature, the Template of the Machining Strategy
can't be changed. You can still add, remove, or reorder the Current
Operations, it is only the template that can't be changed. This
is done because the Template is used to set Cutting Conditions. You can update the operations used in the Default Strategy templates in the DMS Defaults Dialog, or create User Defined Templates with the Save to Defined Template option.
-
The next step is to modify
the Posting parameters for the feature as needed.
-
In the remaining pages of the wizard, you define the operation-level
parameters. This includes the tool data, patterns, parameters,
rapids, leads, advanced feedrates, and MDI for Mill Turn jobs, for each operation that you selected
for the feature.
- If, while moving through the wizard, you notice default values you believe should be updated to fit your needs better, you can select Save Defaults at the bottom of the wizard to save your values to a template. See The Default Parameter Templates topic for more information.
- After defining the feature parameters, compute the toolpath
for the feature and examine the results.
If any changes need made, edit the feature,
and compute to add the changes.
Navigation
To edit a Lathe feature:
Note: The Feature Name
is the top-level item of the Feature in the CAM Tree.
The Lathe Wizard displays.
Introduction
When you create a lathe feature and finish the feature in the
wizard, the feature is added to the CAM job in the CAM Tree. All of
the information from the wizard can be viewed or modified using the
feature in the CAM Tree. Each item of the feature contains a context
menu for you to access various functions and commands.
You right-click each feature item in the tree to access a context
menu. The menus handle various software commands as explained next.
Feature Creation and
Modification
The top level of the feature, which displays the feature name, is
used to edit the feature, add features, and set the feature status
using the following commands.
Note: When
you insert a feature, it
is added below the current feature.

- enables editing of the operation name in the CAM Tree. Type
the new name for the operation.
- Add Note - opens the Add Note dialog to allow you to create a message that can be accessed as a tool tip by hovering over the icon next to the item. Click OK to create the note, and use Add Note again if the note needs to be edited. Editing the note, removing all text and clicking OK removes the note from the item.
Changing Direction
While the 2 Axis Feature does have it own "Default Chain Start Point", many operations contain a "Chain Start Point" item to define where the
tool starts for the individual operation. The initial start point is determined
by the software when the toolpath is calculated. You use the following
items to modify the start point for various operations.
Note: When
using Modify to set the start point and direction of any chain, the
chain geometry must be visible in the graphics area in order for you
to change the start point location.
The following feature item is used to
modify the chain start point (globally) for all operations in a 2-axis
feature.
Default Chain Start Point
- Reverse
Direction - flips the current direction of the chain
start point to force cutting in the opposite direction.
Tip: You
can click some of the CAM Tree items to view a preview in the graphics
area. For example, click Geometry to confirm the assigned feature
geometry, or click an Operation to confirm a computed toolpath.
Operation Stock
Every operation that uses a tool, contains Operation Stock below it.
Operation Stock tracks the effect of previous operations and displays
a cutaway view of the current state of the stock. To utilize the Operation
Stock, select the Trim to Stock option in the Parameters page of an operation.
Operation Stock
Note: The icon shows the Operation Stock is set to default. The
default Operation Stock tracked based on the order of the operations as
they will occur at the machine, not the order of the features in the CAM
Tree. To review the order of operations as they will be called, right-click
on The Turning Job and click Machining
Order.
