Features & Cutting Process:

The lead-in is placed on the tube surface and pierces through the scrap area. The actual cutting action maintains a fixed height and follows the tube surface for cutting.

Features & Cutting Process:

The lead-in is placed outside the tube body. The laser starts from outside the tube and cuts into it without piercing through the tube. The actual cutting action maintains a fixed height for cutting.

Features & Cutting Process:

Same as the lead-in.

Scenario (Standard Lead-out):

When processing tubes, due to gravity, the part might fall before the cutting path finishes. This may cause the laser to hit the part before cutting is complete, leaving burn marks and affecting its appearance. Setting a lead-out line can prevent such burn damage.

Note: Do not place a lead-out line on the left cutting path of a part to avoid cutting air (missing the intended cut).

Features & Cutting Process:

Same as the lead-in.

Scenario (External Lead-out):

If there is a mismatch between the sheet material and the part drawing dimensions, a lead-out line can be added to ensure the part is fully cut.

Before importing parts, turn on [Leads] in 【Auto Technique】.

When importing parts, set the length of the off-board leads in 【Import Parameters】.

Note: Once set here, the lead length of the part drawn in the software will be this value.

Note: If the end face of your part is rounded, you can set the angle of the off-board lead in 【Corrected Y-axis angle】.

After importing the part, click [Lead] in the toolbar.

After importing the part, set the length of the off-board lead in [Profile Toolpath].

Parameter

Interpretation.

There are three types available. The effect of using a Straight + Arc lead-in is shown in the figure below.

Continuous Cutting

When processing tubes, due to gravity, the part may fall before the cutting path is complete. This can cause the laser to hit the part directly before finishing the cut, resulting in burn marks and affecting the part’s appearance.

Setting a lead-out line helps prevent such thermal damage.

Checked: Changes the start point on the cutting face while setting the lead-in.

Unchecked: The lead-in is added to the original start point of the cutting line.

Determines the direction of the lead-in start point on the cutting face.

From the front view of the tube (as shown in the illustration):

• The red circle’s starting point forms a 90° angle with the X-axis.

• The yellow circle’s starting point forms a 180° angle.

Checked: Changes the start point of the hole while setting the lead-in.

Unchecked: Adds the lead-in at the hole’s original start point.

Defined by the Y-axis:

• The far end refers to the side near the end of the tube (e.g., the white point in the red circle).

• The near end refers to the side near the tube head (e.g., the yellow circle).

Defined by relative position:

• For example, the blue circle in the diagram shows a vertex of a square hole.
