This is the fourth recording in a Getting Started series on the iMachining of a Bracket. There are standard 2.5D tool paths (Drilling & Profile) and 3D tool paths (HSR & HSS) to aid in the complete CNC program. These iMachining operations are defined to perform the machining of the three semi-open pockets and the seven closed pockets. A bull nose mill of Ø10 mm (0.375 in) with a corner radius of 1.6 mm (0.0625 in) is used. Since all ten pockets have the same depth, they can all be machined in one operation. The tool enters the semi-open pockets through the open edges. The tool enters the remaining pockets using helical ramping and the defined entry geometry. iRough has a 0.25 mm (0.01 in) allowance on the walls, which is then removed by the iFinish operation.
