Pocket Lead out options
The Lead out option controls the movement of the tool when it leaves the pocket contour on the finishing cut.
None
From the last point of the contour, the tool exits vertically in rapid move.
This option causes the tool to exit while in contact with the pocket wall, which might cause gouging and result in visible marks on the workpiece.
Normal
With a movement normal to the pocket contour, the tool retreats from the last point of the profile.
The length of the normal can be set in the Length field by entering:
– a direct length value.
– a percentage of the
tool diameter used to calculate the length value.
The tool then rapidly travels vertically to the Clearance level.
Arc
With a circular motion tangent to the last entity of the pocket contour, the tool retreats from the profile.
The arc radius can be set in the Radius field by entering:
- – a direct radius value.
- – a percentage of the
tool diameter used to calculate the radius value.
The tool then rapidly travels vertically to the Clearance level.
Arc angle
This parameter defines the angle of the retreat arc segment. The default angle value is 90°; in this case, SolidCAM generates a retreat path of quarter arc.
With the Arc Lead out option, the tool moves normal to the retreat arc at the arc start point.
The following options are available:
Distance
The tool starts at the specified distance from the arc start point. When you select Distance the Normal to arc option is enabled by default. Select Tangent to arc option for the tool to start Milling tangentially to the Lead In/Out moves.
Center
The tool starts at the retreat arc center.
Tangent
The tool retreats from the pocket wall in a movement tangent to the last profile entity.
The length of the tangent line can be set in the Length field by entering:
- – a direct length value.
- – a percentage of the
tool diameter used to calculate the length value.
SolidCAM does not check the Lead out movements against the pocket contour. Check the tool path simulation to make sure that the tool does not gouge the pocket walls or islands.
Same as Lead in
When this check box is selected, the strategy and parameters defined for Lead in are used for Lead out.
