Use the options on this page to reduce the feed rate at the intersections of holes. This enables the tool to slow down and approach these regions safely. If the machine tool has a drilling cycle that supports this option, set it up in the option file (otherwise, on the
NC Program dialog, select a Drilling Cycle Output of
off).
Note: Feed rate intersection is applied to the start of
Single peck,
Ream, and
Counter bore cycle types.
This page contains the following:
Hole intersections — Select to enable feed rate and spindle speed reductions at hole intersections. This gradually slows down the feed rate and spindle speed above a hole intersection and then speeds it up again afterwards.
Note: To reduce feed rates and spindle speeds at hole intersections you need to locate these intersections by selecting
Find hole intersections on the
Hole Feature Sets context menu.
-
Distance — Enter the distance before and after the hole intersection, over which the feed rate and spindle speed decelerates and accelerates.
-
Number of steps — Enter the number of steps over which the feeds and speeds are incrementally reduced.
-
Safety margin — Enter the distance above and below the hole intersection, over which a reduced, constant, feed rate and spindle speed is used. After this distance, the feed rate and spindle speed return to their full values specified in the
Feeds and Speeds dialog. Enter a value to enable the
Feed rate (%) and
Spindle speed (%) fields.
-
Feed rate (%) — Specify the reduced feed rate, as a percentage of the maximum feed rate, used when the tool moves through the safety margins and the intersecting hole .
-
Spindle speed (%) —Specify the reduced spindle speed, as a percentage of the maximum spindle speed, used when the tool moves through the safety margins and the intersecting hole.
Dwell time — Enter the dwell time at each step.
