Activity 8: Machine the countersinks

In this activity, you use a Drilling strategy to countersink the four holes.

Before, showing the 2D Contour toolpath applied around the chamfers on the top surface of the part (left). After, showing the Drill toolpath applied at the conical faces of the four countersink holes (right).

Prerequisites

• Activity 7 is complete.

Steps

1. Confirm that the #3 – Ø1/4" 45° chamfer tool is still selected.

   1. On the Manufacture toolbar, Milling tab, select Drilling > Drill .

      The other three countersinks are automatically selected.

      Important: If Select Same Diameter is disabled (grayed out), it is likely that the edge of the cylinder is selected, instead of the face. Be sure to select the cylindrical faces to use this feature.

3. Set the drilling cycle to Drilling - rapid out and start the calculation.
