Feed Calculation may be based from the tool, material, system default, or be defined by the user. In our case, we will select From tool.

 

Sequence #’s for the program code are set here. Sequence # Start is the starting number for the line sequence “N” numbers in the program. Any starting value can be entered here. Common starting numbers are 1, 2, 5, 10 or 100. Increment, is the sequence number increments for the line sequence numbers. Any value may be entered here. Common increments are 1, 2, 5 or 10. We will accept the default values of 100 and 2.

 

Material type is assigned by selecting from the materials library after pressing the Select . . . button. The user can also change feeds and speeds settings by pressing the Edit . . . button to access the Material Definition Manager. We will accept the default material, Aluminum inch 2024. When all of the settings are completed, press the check mark button to accept them. The stock will be displayed in the graphics display area.

Place a check in the Filter Active check box and then press the Filter . . . button to activate the filters. If this checkbox is not checked, then all 323 tools in the standard database will be displayed in the list. By checking this box to activate this filter the number and type of tools displayed can be refined.

 

From the Tool List filter dialog, press the button labeled as None. Then press the “Endmill 1 flat” button, so that end mills only will be displayed and press the check mark to accept. A list of only end mill tools will be displayed. Select the 3/16 inch diameter end mill from the list (#234) by double clicking on it. The chosen end mill will now be moved into the upper portion of the tool display area window of the Tools Manager.

 

This is the only tool needed for the program in our example so press the check mark to accept and close the dialog. If additional tools are needed, the same process may be followed to add them. Now, all the Machine Group setup information is complete and the geometry creation may begin. Any of the items that have been set so far can always be edited, if required.
