Checking this box enables the Acc-n-Dec feature at the cut level. Acc-n-Dec will output feedrate changes in the code depending on the geometry the tool is cutting and the maximum feedrate programmed.
Check this box to apply Acc-n-Dec feedrate changes to the next tool path you make. To get the feedrate changes in the code, you would also check the Acc-n-Dec button in the Sequence Options.
For more information on configuring the ACC-N-DEC options, please refer to the Acceleration/Deceleration notes in the 'Make NC Code Options' section.
If you wish to disable Acc-n-Dec later, de-select Acc-n-Dec in the Sequencer to skip insertion of feedrate changes for all tool paths in the program.
In the code example below, each of the feedrate changes have been highlighted.
