In the Defining a New Drilling Method example you did not define any tools. PowerMill determines the required drills given the hole size and the radial thickness specified. If you look at the tools defined, they are:
- A drill with diameter of 4.5 inches.
- A drill with diameter of 4.46 inches, created because of the Radial thickness of 0.02 used when Deep drilling.
- A tap with diameter of 4.5 inches.
- A drill with diameter of 1.5 inches.
- A drill with diameter of 1.46 inches, created because of the Radial thickness of 0.02 used when Deep Drilling.
- A tap with diameter of 1.5 inches.
You can specify a tool in any of the following ways:
- Define a tool from the
Create tool list in the Drilling dialog. - Select a tool from the
Tool list in the Drilling dialog. - Define a drill or tap with a specified Diameter in the Drilling dialog. PowerMill determines whether to create a Tap (if the Strategy is Tapping) or a Drill (for any other Drilling strategy) in the Drilling dialog.
- Define a drilling tool with a diameter specified by the hole size less the Radial thickness
in the Drilling dialog. In this case you do not specify any tool and let PowerMill determine the tool automatically. - Define a drilling tool with a diameter specified by the hole size. In this case, you do not specify any tool and let PowerMill determine the tool automatically.
