Edit the Tool of a Machining Operation

	This task shows you how to edit the tool of a machining operation. A machining operation always has a tool assigned to it (default tool, for example). You can modify this tool in several ways: edit its characteristics, thereby creating a new tool replace it by selecting another tool that is already used in the document replace it by selecting another tool by means of a query.
	1.	Double-click a machining operation (a Pocketing operation, for example) in the program. The machining operation dialog box appears. Select the `Tooling` tab page then select the `Tool` tab .
	2.	To create a new tool: If you want to change tool type, select the icon corresponding to the desired tool type. In this case the corresponding tool representation appears in the 2D viewer. Double-click the geometric parameter that you want to modify in the 2D viewer, then enter the desired value in the Edit Parameters dialog box that appears. Modify other parameters in the same way. The tool representation is updated to take the new values into account. Click More to expand the dialog box to access all the tool's parameters. Modify the values as desired. Use the spinner to increment the Tool number. Enter a name for the new tool.
	3.	To select a tool that is already used in the document: Select the button opposite Name. Select the desired tool from the list of tools already used in your document. The tool representation is displayed in the 2D viewer. It can be edited as described above.
	4.	To select another tool by means of a query: Click the `Select a tool with query` icon opposite `Name`. The `Search Tool` dialog box appears.
		In the `Look in` list, specify where you want to search for the tool: in the current document in a tool catalog in an external tool database such as the TDM (Tool Data Management) or CATIA Version 4 Manufacturing database.
		If you want to change tool type, select the icon corresponding to the desired tool. You can do a quick search in the `Simple` tab page by means of a character string on the tool name or a value for the tool's nominal diameter. The tools meeting the simple search criteria are listed. Select the desired tool from the list and click OK. The tool representation is displayed in the 2D viewer. It can be edited as described above.
		You can search a tool using finer constraints by selecting the `Advanced` tab page. The example below shows the result of a search for a tool with body diameter between 8mm and 12mm in the catalog ToolsSample02.
	5.	To make query without Tool Type: Click `Select a tool with query` icon opposite `Name`. The `Search Tool` dialog box appears. Select `All Tool`s. All tools under the applicable tool types are displayed in the tools list (in this above example, all face mill, end mill, T-slotter tools are displayed). The table shows all the attributes of all possible types. Click `Advanced` tab. Define a tool query using attributes that are common to the applicable tool types.
	5.	Click `OK` to confirm using this new tool in the operation.
		The new tool, selected from a tool catalog or an external tool database, will not be used in the operation: if the tool number of the new tool already exists in the Resource List if the new tool does not exist in the Resource List. Cutting conditions (feeds and speeds) can be included in a tool catalog and in the TDM. Please refer to Feeds and Speeds for more information. The TDM can allow several cutting speed and feedrate data for each tool. This information is displayed at tool selection time. The feed and speed information of the selected tool is used in the machining operation definition. Realistic DXF user representation of tools can be selected from the TDB. These can be used in tool path replay as well as Photo and Video simulations.
