length：Length allows you to determine the distance along which the tool will slow down by specifying One of the following two options.
Previous Tool indicates that the length of the slowdown move is determined either by the diameter of the previous tool or any diameter you enter in the Tool Diameter field. Slowdown begins and ends at the points of tangency of the tool diameter and the part geometry.
Percent Tool indicates that the length of the slowdown move is determined by a percentage of the current tool diameter; you enter the percentage in the % Tool Diameter field. Slowdown begins and ends at the points of tangency of the tool diameter and the part geometry.
Slowdown%
Slowdown% determines the slowest feed rate during slowdown. It is a percent of the present feed rate. For example, if the current feed rate is 30 ipm and this option is set to 10 %, then the Slowdown Feed Rate will step down to 3 ipm before accelerating
Number Of Steps
Number Of Steps allows you to set the abruptness of slowdown. The greater the number, the more even the slowdown. The feed rate reduction per step is:
(100% - Slowdown %) / No. of Steps.
The number of acceleration steps is approximately one-half of the number of deceleration steps. In other words, the tool accelerates faster than it decelerates. The following figure shows use of Slowdowns with several other option setting, and Number Of Steps = 5.
