These parameters are in the Feed Optimization dialog:
Increase feed when load is below % of target horsepower — The programmed power is the estimated horsepower displayed in the Operations List. This percentage is applied to the estimated horsepower and the feed rate is increased for any move that requires less power.
But do not increase feed beyond % of programmed feed — Enter the maximum percentage to increase the feed rate over the operation's initial feedrate.
Decrease feed when load is above % of target horsepower — The programmed power is the estimated horsepower displayed in the Operations List. This percentage is applied to the estimated horsepower and the feed rate is decreased for any move that requires more power.
But do not decrease feed below % of programmed feed — Enter the minimum percentage to decrease the feed rate.
Perform super sampling to calculate instantaneous tool load — Set this option to create a more accurate sampling of the tool loads by sampling the loads at a number of points along the toolpath and then averaging these loads for each NC block. If this option is turned off a single tool load is calculated for each block of NC code.
Number of times to measure tool load — If Perform super sampling is selected, then you can enter how many times per minute to calculate the tool load. To calculate the load for each NC block, the loads are averaged. The larger this number is, the longer the feed optimization takes.
Use different feed rates on a single block — A long cut may have varying tool loads. If you want to break up NC blocks so that you can more finely control the feed rates, check this option.
This option increases the size of your NC program.
Distance to split toolpath — If you select Use different feed rates on a single block, then this parameter controls how often the toolpath is broken up. It is specified as a percentage of the tool diameter.
OK — Click the OK button to optimize feed rates for the part.
