Path Optimization

Definition:
Path optimization is a crucial aspect of improving the efficiency of laser cutting. The main goal is to reduce the movement distance and time of the laser head. The primary objectives include meeting the process requirements of laser processing and enhancing processing efficiency.

Key Principles of Path Optimization:

1. Shortest Path Principle:
   Choose the shortest cutting path to minimize unnecessary idle movements. This reduces the overall time spent during the cutting process.

2. Adjacent Cutting:
   For multiple adjacent cutting parts, prioritize cutting adjacent parts to reduce the back-and-forth movement of the laser head, thereby saving time.

3. Grouping:
   Group similar or identical patterns together for cutting, optimizing the cutting sequence, and shortening the overall cutting time.

4. Simulation and Adjustment:
   Use software to simulate the cutting path, check for any inefficiencies, and adjust the design to ensure optimal cutting performance.

1. Layered Processing Order:
   In a single processing cycle, various processes may need to be mixed. Typically, surface or contact-based processes (e.g., laser drawing, engraving, or brush processing) should be performed first, followed by non-contact or through-cut processes. The processing order of layers should be set according to the specific processing scenario.

2. Inside-Out Cutting:
   To avoid the risk of materials falling off after being cut through, which could prevent completing the inner contour, cutting the interior first before cutting the exterior is recommended.

3. Finding the Cutting Starting Point:
   The starting point for cutting can be influenced by factors such as laser power and the material's initial penetration. To minimize defects, choosing an appropriate start point (e.g., concave or convex corners) helps reduce impact on critical surfaces, improving the overall quality of the workpiece.

4. Block Processing Direction:
   The direction in which processing is carried out (e.g., bottom-to-top, top-to-bottom, left-to-right, right-to-left) is designated to ensure an orderly process, avoid large jumps, and enhance safety during the simultaneous processing and material collection.

5. Automatic Determination of Starting Points and Directions:
   Beyond process requirements, increasing efficiency involves minimizing idle movements by starting cutting from the nearest points. This requires adjusting the starting points (for closed shapes) and cutting directions (for non-closed shapes) of the original design.

6. Gap Compensation Optimization:
   For equipment with lower performance or insufficient step precision, appropriate gap compensation is applied to the processing patterns, ensuring better accuracy in the final product.
