Feed optimization is an optional process that evens out the tool load by adjusting a program’s feedrates. This optimization is performed so that the horsepower required for the cuts approximates a target horsepower. In the graph shown below, the initial feedrates are shown in white. The optimized feedrates are shown in black. Notice how the black curve removes the spikes in the tool load.
To optimize the feedrates of your program:
Generate toolpaths
Set the target horsepower milling attribute for the operations you would like to optimize. Note that for 2 ½ D finish milling operations, it is recommended that you use Peripheral feeds instead.
Select Feed optimization from the Manufacturing menu.
Set the parameters appropriately
Click OK.
For complicated parts this task can take several minutes.
Note that if the NC code is regenerated, the optimized feedrates will be lost.
It is helpful to graph the tool load during 3D simulation before and after the optimization to see the changes.
To remove the optimized feed rates without regenerating the NC code, click on the Clear optimized feeds option in the Manufacturing menu.
