Laser Cutting Dividing Line Control for Reliable Scrap Drop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser processing machines fail to effectively remove scraps from between skids due to improper setting of dividing lines, leading to welding or abrasion of skids and reduced scrap falling efficiency.
Innovation Solution
A laser processing machine with a control device that sets dividing lines at specific distances from skids to prevent welding and ensure scrap removal, calculating the gravity center of the scrap and adjusting the dividing line position to maintain a safe distance from interfering skids, thereby optimizing scrap falling and reducing skid abrasion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the dividing line is set without considering skid position, then the opening forming area can be divided into equal parts, but the cut scrap may be welded to the skid and fail to fall off
Solution Approach 1:
The patent applies local quality by making the dividing line position variable rather than uniform. The control device calculates the gravity center of the opening forming area and sets the dividing line at a position that maintains a predetermined distance from the nearest skid, rather than simply dividing the area into equal parts. This localized adjustment ensures that the scrap's gravity center is positioned away from the skid, preventing welding and ensuring reliable scrap removal.
2Device complexity
If the dividing line is set without considering skid position, then the division process is simple, but the skid may be fused and abraded
Solution Approach 1:
The patent applies preliminary action by calculating the gravity center of the opening forming area and determining the optimal dividing line position before the actual cutting process begins. The control device computes the distances from the gravity center to adjacent skids and sets the dividing line at a predetermined distance from the nearest skid, preventing potential welding and abrasion issues before they occur.
3Reliability
If the gravity center of the cut scrap is proximate to the skid, then the scrap may remain on the skid, but increasing the distance requires complex dividing line positioning
Solution Approach 1:
The patent applies self-service by using the gravity center of the opening forming area as the basis for automatically determining the dividing line position. The control device calculates the gravity center coordinates, determines the distance to adjacent skids, and autonomously sets the dividing line at a position that maintains the predetermined distance from the nearest skid. This self-adjusting mechanism ensures reliable scrap removal without requiring complex manual positioning.

AI summary
An NC device controls a processing machine body so as to form an opening by cutting the periphery of an opening forming area in a material. In a case where a skid interferes with the opening forming area and the interfering skid is positioned within a margin from a first gravity center of the opening forming area in an alignment direction of the skid, the NC device controls the processing machine body so as to cut the opening forming area with a dividing line set at a position that is apart by a predetermined distance from the skid in the alignment direction of the skid. The predetermined distance is a distance in which the material is not welded to the skid, and is a distance in which a second gravity center of a scrap interfering with the skid is positioned at a distance longer than the margin from the skid.
