Reducing feed rates at hole intersections

This example shows you how to find the hole intersections and reduce the feed rate and spindle speed at these intersections.

Starting with a model containing two feature sets, one containing three holes (grey), the other containing two holes (magenta).

1. From the Hole Feature Sets context menu, select Find hole intersections. This creates intersections wherever the two sets of holes intersect fully or partially.

   

2. Create a block and drill tool.
3. Display the Single Peck Drilling dialog.
4. Select the Feed rate reduction page:
   1. Select Hole intersections.
   2. Enter a Safety margin of 30 in the Hole intersections area.
   3. Enter a Distance of 20 in the Hole intersections area.
   4. Enter a Feed rate of 40 in the Hole intersections area.
   5. Enter a Spindle speed of 20 in the Hole intersections area.
   6. Enter a Number of steps of 3.
   7. Enter a Dwell time of 1.
   8. Click Calculate.

   This creates a drilling toolpath which slows down at the hole intersections.

5. Click Toolpath tab > Draw > Display > Points to show each step.
