Using the Feeds and Speeds dialog

To load the recommended values for a tool

  1. Create a new tool with a valid diameter.
  2. Add Cutting Data to the tool:
    1. Click the Cutting data tab.
    2. Click to display the Edit Cutting Data dialog and enter the appropriate Axial Depth of Cut and Spindle Speed.

      These values are taken as the recommended values on the Feed and Speeds dialog.

  3. Click Home tab > Setup panel > Feeds & Speeds to display the Feeds and Speeds dialog with the recommended values from the active tool.
  4. Click to load the recommended values from the active tool.

    You can also manually edit individual values. The manually edited fields are shown with a .

The Spindle Speed is Surface Speed x 1000/3.14 x Tool diameter or, as a formula: n = Vc.1000/(.Dc). Editing either the Spindle Speed or Surface Speed automatically updates the other.

The Cutting Feed Rate is Number of teeth x Feed per tooth x Spindle Speed or, as a formula: Vf = Zn.fz.n. Editing either the Cutting Feed Rate or the Feed/Tooth automatically updates the other.

The Plunging Feed Rate is Cutting Feed Rate x Feed Rate Plunge Factor or, as a formula Vp = Fp.V

Define the Feed Rate Plunge Factor on the Tools > Feeds and Speeds page of the Options dialog available from File tab > Options.

You can use the Feeds and Speeds dialog to make changes to the Surface Speed and Feed/Tooth values of an active, calculated toolpath. Make the changes and click Apply on the Feeds and Speeds dialog, this modifies the values of Spindle Speed, Cutting Feed Rate, and the Plunging Feed Rate and applies them to the toolpath without recalculating it. You can view the changes in the Feeds and Speeds page of the toolpath dialog.

Any field on the Edit Cutting Data dialog with a value of 0.0, or no value, is not fed through to the Feeds and Speeds dialog.
