Enable: The lead is formed from the center of the hole.

Disable: The lead is formed according to the Lead in/out for closed curves or Lead in/out for open curves rule.

Off. The Engage and Retract toolpath parts is not generated.

By Vertical Normal. The engage is performed along the tool axis to the first point of the work pass.

By Surface Normal. The engage is performed along the normal to surface at the first point of the work pass

By Horizontal Normal. The engage is performed perpendicular to the tool axis to the first point of the work pass

By Tangent. The engage is performed tangentially to the first machining point.

By Line. The engage is performed by angle to tangent to the first machining point.

By Vertical Arc. The system adds an arc to the first point on the curve using the defined radius. The arc lies in the vertical plane and is tangent with the first toolpath applied to the contour. The angle of the curve is defined by user. The tool plunge is performed at the vertical end of the arc, and then moves along the arc and then onto the work pass.

By Normal Arc. The system adds an arc to the first point on the curve using the defined radius. The arc lies in the vertical plane and is tangent with the first toolpath applied to the contour. The angle of the curve is calculated so that the tangent on the other side of the arc is vertical. The tool plunge is performed at the vertical end of the arc, and then moves along the arc and then onto the work pass.

By Horizontal Arc. Used when constructing a trajectory in the horizontal direction. The system adds a tangent with an angle in the horizontal direction.

Depending on the engage, it becomes possible to control additional parameters:

Length (Radius). Changes the length

Angle. Changes the vertical angle

Plane angle. Changes the horizontal angle

Off. The Engage and Retract toolpath parts is not generated.

By Vertical Normal. The retraction – along the tool axis from the last point of the work pass.

By Surface Normal. The approach is performed along the normal to surface at the first point of the work pass

By Horizontal Normal. The retraction is performed perpendicular to the tool axis from the last point of the work pass.
