Technics

This section introduces technics you can set in Double-tool CNC System.

If there is no special instruction, please set technics in Operator page.

Add a Chamfer

It is used to add chamfers to objects whose angles are less than 180°, so as to improve cutting effect on corners of thick material.

To add a chamfer, select the target object, and do the following:

  1. To open Chamfer dialog box, right click on the function window, and select Chamfer:

  2. Set parameter Angle and Radius.

  3. Optional: To automatically add chamfers for closed objects according to the attribute of fill/unfill, check Create Chamfer by Fill or Unfill.

The system automatically adds a chamfer at the angle that meets the demand.

Taking setting parameter Angle to 45°~90° and checking Create Chamfer by Fill or Unfill as an example, the result is as follows:

Set Unfill or Fill

It is used to reserve a certain part of closed objects. For objects with Unfill attribute, the system reserves the outer part; for objects with Fill attribute, the system reserves the inner part.

To set unfill or fill, select closed objects, and do the following:

  1. Right click on the function window, and click Unfill/Fill.

  2. Select one of the following:

    • To manually set the selected objects as unfill/fill, select Unfill / Fill.

    • To set the selected objects as unfill by default, select Auto Setting.

Set a Lead Line

It is used to avoid machining errors or damage to the workpiece caused by laser staying above the start position for a long time, so as to improve machining accuracy.

The type of lead line differs in the leading direction:

  • Lead-in line: consisting of line lead line, arc lead line and hook lead line.

  • Lead-out line: consisting of line lead line and arc lead line.

To set a lead line, select the target object, and do the following:

  1. To open Set dialog box, right click on the function window, select Lead Line → Set.

  2. Select a type for the lead line according to the cutting technics.

  3. Set related parameters of the lead line.

    See Parameters for details.

  4. Optional: If the target object is a closed object, in Seal area, select one of the following:

    • Gap: The lead line is unclosed and the cutting head will not cut through at the sealing position.

    • Over: The lead line is closed and the cutting head will cut at the sealing position.

  5. Set the position of the lead line:

    • If you check Automatic Lead Position, do one of the following:

      • To automatically set the lead line at the position with a larger angle in the object, check Corner first.

      • To automatically set the lead line at the longest edge of the object, check Edge first.

    • If you check Set by Universal (0~100) param. The position of the lead line is the set ratio times the total length.

    • If you check Set by Mouse, click on the edge of the object after the cursor turns into to specify the position of the lead line.

  6. In Options Area, select one of the following:

    • Retain Position, Change Leads Type

    • Retain Leads Type, Change Position

  7. Optional: Manually modify the lead line:

    1. To call Start Point command, Right click on the function window, select Lead Line → Set Start Point.

    2. Do one of the following:

      • To modify the position of the lead-in line, left click on the edge of the object.

      • To draw a line-type lead-in line from outside to the edge on the object, left click on the outside and the edge of the object.

The result is as follows:

Parameters

  • Angle: For a line-type lead line, it refers to the angle between the lead line and the tangent line of the intersection; for an arc-type lead line, it refers to the central angle.

  • Length: For a line-type/arc-type lead line, it refers to the length of the line/arc; for a hook-type lead line, it refers to the sum of the radius of the arc and the length of the line.

  • Radius: For a hook-type lead line, it refers to the radius of the arc.

  • Add Tiny Circle in Start Point: Add a tiny circle at the start point of the lead-in line, so as to solve the problem that the accumulation of slag influences cutting effect during piercing a thick tube.

  • Circle Radius: The radius of the hole at the start point of the lead line.

Set Kerf Compensation

There exists deviation between the sizes of actual cutting parts and theoretical ones, which is caused by the kerf during cutting. The deviation leads to a smaller size in the outer contour and a larger size in the inner contour. This operation is used to compensate the deviation.

The type of kerf compensation includes the following:

  • All shrink: shrink the cutting area for all selected parts.

  • All expand: expand the cutting area for all selected parts.

  • Unfill: shrink; fill: expand: shrink the cutting area for parts with unfill attribute, and expand the cutting area for parts with fill attribute.

To compensate the kerf, select the closed objects, and do the following:

  1. To open Kerf Compensation dialog box, right click on the function window, and select Kerf Compensation:

  2. Select a compensation type.

  3. Set the inner width and outer width.

  4. Optional: To save the commonly used inner width and outer width for later use, do the following:

    1. In the drop-down box of Configuration, select Edit. Configuration dialog box pops up:

    2. Click Add, set a name in Description column, set the inner width in Inner Width column, and set the outer width in Outer Width column.

    3. For later use, in the drop-down box of Configuration, select the set name. The system automatically fills in the inner width and outer width.
