Update Input Stock - Automatic Mode

	This task shows you how to update the input stock automatically for the machining operations in a lathe manufacturing program. These machining operations can be lathe operations, and axial operations along the spindle axis. In Automatic mode, the input stock takes into account all the previous operations. The axial operations must be completed and the lathe operations that use a stock must have either a manually selected stock or a saved input stock. Please refer to How to Update Input Stock for more information about this capability.
	1.	Select `File > Open` then select the StartStockUpdateAutoMode.CATProcess document
	2.	Select `Machining > Lathe Machining`from the `Start` menu. The Lathe Machining workbench appears. The part is displayed in the Setup Editor window along with the manufacturing specification tree.
	3.	Double-click Part Operation.1 in the tree to display the Part Operation dialog box. Right-click the Stock field to make sure that `Automatic Stock Selection for Turning Operations` is activated in the contextual menu.
	4.	Right-click the drilling operation in the tree and select the Replay Tool Path icon to replay the operation Click OK in the Replay dialog box. The operation status in the tree is now `Computed`.
	5.	Double-click the lathe recessing operation in the tree. Select the Strategy tab in the machining operation editor. Note that: the color of the stock area indicates that stock selection is optional the Input stock status is `Not computed` and that the automatic Stock selection is activated (`Auto. selection`).
	6.	Click the Tool Path Replay icon to replay the operation. Click OK in the Replay dialog box.
	7.	In the Strategy tab the Input stock status is now `Up to date`. Click OK in the machining operation editor.
		In the manufacturing specification tree, the operation status is `Computed` and `Stock up to date`.
		Computing Stock and Tool Path For modifications to the Part Operation, previous operation in the program (edit) or previous sequence of the program (delete or copy/paste), the stock status becomes `Stock to update`. In this case you can right-click the Manufacturing Program in the tree and select the `Compute Stock and Tool Path` contextual command. All input stocks and tool paths of the operations in the program are recomputed. Please note that when you copy/paste an operation, the input stock is not copied. Removing Input Stock If you right-click the `Input stock status` field in the Geometry tab page, you can use the `Remove Input Stock` contextual command to remove the operation's input stock. The corresponding sketch profile will be deleted. The status of the previously selected geometry from the deleted sketch will be Not found, so new geometry must be selected in this case. You cannot use the operation's `Cancel` button to recover the deleted sketch.
