Approach

This section enables you to select between the Feed and Rapid type of movement when the tool is approaching the start level of the thread path.

The passes through options are related to link movements within a single thread (Links between rough and finish passes, etc. ).

The separate areas through options are related to link movements between multiple threads.

Lead In / Lead Out

You can choose from following types of Lead In/Out movements and customize them with the following parameters:

Normal

The tool approaches the profile and retreats away from/to a point normal to the profile.

The Length (value) field sets the length of normal line.

Start from Center of circle geometry

The Start from Center of Circle geometry parameter is available only for the Internal thread type. When selected, the lead-in path will start from the center of the thread geometry. The Length parameter is disabled and will be not taken into account.

Radius (value) - This field sets the radius of the lead-in/out arc.

Arc Angle - This field defines the angle of the lead-in/out arc segment.

Distance - The tool starts milling at the specified distance from the arc start point.

Center - The tool starts milling at the lead in the arc center.

Start from Center of Circle geometry

The Start from Center of Circle geometry parameter is available only for the Internal thread type. When selected, the lead-in path will start from the center of the thread geometry. The Distance and Center options are disabled and will be not taken into account.

Flatten - When this option is selected, the lead-in arc will be created only in plane XY. If this option is not selected, the lead-in arc should copy the pitch of the thread path in Z axis.

Tangent

The tool approaches the profile and retreats away on a line tangent to the profile.

This option is enabled when External is selected in the Technology page- Thread data Cut from section.

Length (value) - This field sets the length of the tangent line.

Angle - The lead-in/out tangent line can be modified in this field.

Normal - This field defines the length of the normal line.

Flatten - When this option is selected, the lead-in arc will be created only in plane XY. If this option is not selected, the lead-in arc should copy the pitch of the thread path in Z axis.
