Machining Path Editing for Suction Cup Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In machining processes, especially with large parts in industries like aerospace and marine, the use of fixed molds leads to high machining costs and insufficient production line flexibility due to cumbersome mold disassembly and assembly, and there is a risk of interference and collision between machining equipment and support units if the machining path is not properly planned to account for the space of the support equipment.
Innovation Solution
A method and system for editing the machining path to avoid interference by setting suction cup ranges for support units, inserting flags at specific intervals, and editing coordinates and instructions for descend and ascend actions to ensure the machining equipment dodges the support units, implemented through two-way communication between the machining and support equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the machining path is planned without considering the space of the support equipment, then the machining path planning is simple and fast, but the knife of the machining equipment may interfere and collide with the support unit during machining
Solution Approach 1:
The machining path is edited in advance to include dodge instructions before machining begins. The control device pre-processes the machining path to identify sections where the knife may collide with support units and inserts corresponding dodge instructions, allowing the support units to adjust their positions proactively rather than reactively during machining.
Solution Approach 2:
A control device acts as an intermediary between the machining equipment and support equipment. This control device processes the machining path, identifies potential collision zones, and generates dodge instructions that coordinate the movements of both machining and support equipment, enabling them to operate harmoniously without direct interference.
2Adaptability or versatility
If fixed molds are used in the machining process, then the machining process is simple, but the mold disassembly and assembly is cumbersome and requires huge storage space
Solution Approach 1:
The support equipment is divided into multiple independent support units that can be individually adjusted and positioned. Each support unit can be independently controlled to provide localized support, replacing the need for large fixed molds while maintaining the necessary support functions during machining.
Solution Approach 2:
The support units are designed to be dynamically adjustable during the machining process. Their positions and configurations can be changed based on the specific machining requirements, allowing the same support equipment to adapt to different workpieces and machining operations, thereby improving production line flexibility.

AI summary
A dodge method of machining path and a machining system is provided. By inserting a flag into an original machining path, an interference between the flag and a suction cup of a support unit is determined. A coding instruction is inserted at the interference to edit the original machining path, thereby generating an edited machining path. Therefore, when a machining equipment executes the edited machining path, the support unit may smoothly dodge a knife of the machining equipment.
