The following Entry/Exit tab is displayed for the 2½ Axis Hole Pocketing operation. Entry and Exit determines the way in which tool enters and leaves the part geometry. MILL Module allows you to specify how the cutter approaches, engages, retracts and departs when starting and stopping a cut.
|
The maximum helix diameter that can be set would be equal to difference of hole and tool diameter. When this condition is met, there would be no spiral motions.
 Dialog Box: Entry/Exit tab, 2½ Axis Hole Pocketing Operations |
The cutter approaches and engages and the type of transfer motions during the cutting cycle can be specified here. The engage can be a helical engage, which is achieved by specifying the Helix Diameter (Hd) and the Helix Pitch, specified as an Angle (A) or Height (H). The helix diameter must be less than the difference of the hole diameter to the tool diameter. The Approach Distance (Ad) can also be adjusted. |
Selecting this option converts a partial helix to a full helix. When checked you can also optionally check Output each helix individually. This will split the helixes into individual helix of 360 degrees each in the posted code. |
