Activity 10: Pencil cut2

In this activity, we will use use the 3D Pencil strategy again, to reduce the amount of stock in the corners of the cavity, with a smaller tool.

Previously we used a 3 mm ball mill. Now we will use a 2 mm ball mill.

Prerequisites

• Activity 9 is complete.

Steps

1. Start a new 3D Pencil operation and, from the Tutorial Tools (Metric) library, select the #23 - Ø2 mm R1 mm ball tool.

   1. On the Manufacture toolbar, Milling tab, select 3D > Pencil .
   2. On the Tool tab , click Select. This opens the tool library.
   3. In the Tool Library dialog, select Fusion Library > Tutorial Tools (Metric).
   4. From the list, select #23 - Ø2 mm R1 mm (Ball end mill).
   5. Click Select.

2. Stepover cut value, cut angle.

   1. Click the Passes tab .
   2. Set Stepover to .08 mm.
   3. Set Number of Stepovers to 11.
   4. Click OK to begin calculating the toolpath.

Activity 10 summary

In this activity you selected a 3D Pencil finishing operation and used a smaller tool to clean out the fine corners.

The calculated toolpath is shown below.	The Simulated toolpath is shown below.

The toolpath is shown with a red arrow start, yellow rapid move, green lead in/out move, blue cutting moves and a green arrow at the end.
