Cutting Apparatus Boundary Frame for Waste Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting apparatuses generate significant waste and are cumbersome when cutting patterns from larger sheets, as they require manual removal of unnecessary parts, leading to inefficiencies and increased material waste.
Innovation Solution
A cutting apparatus with an arranging unit that sets a minimum boundary frame around patterns, a cutting data generating unit that creates outer line cutting data to separate the pattern from unnecessary regions, and a control program that automates the cutting process to minimize waste and streamline the removal of unwanted material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual removal of unnecessary sheet parts is performed, then pattern can be removed clearly without damage, but waste of sheet increases and operation becomes troublesome
Solution Approach 1:
The cutting process is segmented into two distinct phases: first cutting only the outer line boundary frame that encloses the pattern, then separately removing the pattern. This segmentation allows the unnecessary sheet parts outside the boundary frame to be easily separated and discarded without affecting the pattern integrity, thereby reducing sheet waste while maintaining clear pattern removal.
Solution Approach 2:
The outer line boundary frame is cut in advance before pattern removal. This preliminary cutting action creates a clear separation boundary between the pattern area and unnecessary sheet parts, making subsequent pattern removal easier and more precise while allowing efficient disposal of excess sheet material.
2Ease of operation
If entire unnecessary part of sheet is removed, then pattern can be easily accessed, but amount of waste sheet increases
Solution Approach 1:
The cutting operation is applied locally only to the boundary frame surrounding the pattern rather than removing all unnecessary sheet parts. This localized approach creates just enough separation to make the pattern accessible while preserving the maximum amount of usable sheet material, thereby reducing waste without compromising pattern accessibility.
3Device complexity
If conventional cutting method is used, then simple apparatus structure is maintained, but productivity decreases due to manual work
Solution Approach 1:
The system generates cutting data automatically by calculating the outer line boundary frame from pattern coordinates, eliminating the need for manual intervention in determining cut paths. This self-service approach maintains simple apparatus structure while significantly improving productivity by automating the data generation process.

AI summary
A cutting apparatus is disclosed in which a cutting blade and an object to be cut are moved relative to each other so that a desired pattern is cutout of the object. The cutting apparatus includes an arranging unit arranging the pattern in a cut-allowable region of the object, a frame setting unit setting a minimum boundary frame which is polygonal or curved in shape and includes a contour of the pattern arranged by the arranging unit, and a cutting data generating unit generating outer line cutting data for cutting an outer line dividing a first region near the pattern within the cut-allowable region and a second region other than the first region, outside the boundary frame, based on the boundary frame. The pattern and the outer line are cut out of the object based on pattern cutting data for cutting the pattern and the outer line cutting data.
