Toolpath optimisation

With conventional machining, the feed rate is set at a constant speed determined by the most demanding aspect of the toolpath. The Optimize Feed Rates option analyses the toolpaths created in ArtCAM and adjusts the feed rate to give a constant rate of material removal. Benefits include:

To optimise the feed rate in calculated toolpaths:

  1. Click the Batch Calculate Toolpaths button to display the Batch Calculate Toolpaths dialog.
  2. Select Optimize Feed Rates. The Toolpaths Available For Calculation area displays the names of calculated toolpaths in black and the names of uncalculated toolpaths in red.
  3. In the Toolpaths Available For Calculation area, select the toolpaths you want to optimize. You cannot optimize the feed rate of uncalculated toolpaths.
    Important: You cannot optimize the feed rate in a calculated Drill Bank toolpath. If any Drill Bank toolpaths are selected, a message is in the Status area confirms these toolpaths are ignored.
  4. If you want to adjust the optimization settings, click Settings to display the Optifeed Parameters dialog.
  5. Click the Start button to optimize the selected toolpaths. If you want to cancel the process, click Stop.

    The effects of the optimization process on the toolpaths are shown in the 3D view:

    • Yellow indicates the feed rate is increased by more than twice its original speed.
    • Orange indicates the feed rate is increased by up to twice the original speed.
    • Red indicates the feed rate is unchanged.
    • Green indicates the feed rate is reduced.

Tip: You can also check the results of the optimisation process in the Toolpath Summary Information dialog and compare the speed of the Machining Time against the Optifeed Time.
