Approach Type

Allows user to choose between Outer Diameter (OD), Front Facing and Inner Diameter (ID).  The toolpaths are generated for the selected approach types.

In rouging and finishing operations, for tools with OD orientation, the approach type can be set to Outer Diameter or Front Facing. For tools with ID orientation, the approach type is automatically set to Inner Diameter.

Global Parameters section allows you to set the tolerance value to be used in machining. A uniform thickness or stock that needs to be left around the part can be specified here.

Tolerance  

This is the allowable deviation from the actual part geometry plus the Stock layer (if any).

Stock (Roughing Operations Only)  

This is the layer of material that will remain around the part after the toolpath is completed. Generally Roughing operations leave a thin layer of stock, unlike finishing operations where this value is usually set to zero.

This allows you to select an area to contain the toolpath. This is useful in cases where a section of the part needs to be machined. This is done by selecting the check box for Select containment Start & End points.

Cut Containment

You can either input the X and Z coordinate values that represent 2 corners of a containment rectangle or use the pick option to graphically select 2 corners of a rectangle for containment.

A containment rectangle is displayed in the viewport.

Cut Containment Examples for Turn Roughing

If containment is not specified, the roughing toolpath is generated for the turn part geometry based on the approach type and the defined stock geometry.

Turn Roughing Example without Cut Containment

This allows user to select areas to be excluded from the turn part geometry for toolpath computation. This is done by selecting 2 points on the part geometry. A line is inserted between the 2 selected points as avoid region and this now becomes part of your turn part geometry.  One or more avoid areas can be selected.

Defining Avoid Sections

To select an area to avoid: From the Global Parameters tab in the Turn Operations dialog box, click Select Section under Avoid Sections and pick 2 points on the part geometry. The selection is now displayed under avoid selection. Selecting an Avoid Region from the list highlights it on the part geometry.
