Cutting Apparatus Angle Optimization for Single Pattern Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting apparatuses are inefficient in reducing cutting time when processing a single pattern, as they are optimized for cutting multiple patterns with connected cutting lines.
Innovation Solution
A cutting apparatus that calculates and adjusts the cutting time based on various arrangement angles of a pattern relative to the cutting directions, determining the optimal angle to minimize cutting time by simultaneously moving the cutting blade and object in perpendicular directions.

1Productivity
If patterns are arranged to lie next to each other with connected cutting lines, then cutting time is shortened for multiple patterns, but cutting time cannot be reduced when a single pattern is to be cut
Solution Approach 1:
The patent changes the arrangement angle parameter of the pattern to optimize cutting time. By rotating the pattern at predetermined angle intervals (0°, 45°, 90°, 135°) and calculating cutting time for each angle, the system determines the optimal arrangement angle that minimizes cutting time, making the system adaptable to both single and multiple pattern cutting scenarios
Solution Approach 2:
The patent introduces dynamic angle adjustment capability where the pattern arrangement angle is not fixed but can be changed and optimized. The control device dynamically selects the best arrangement angle based on calculated cutting times, enabling adaptive optimization for different cutting scenarios including single pattern cutting
2Productivity
If the cutting blade and object move simultaneously in perpendicular directions, then cutting efficiency is improved, but the complexity of control increases
Solution Approach 1:
The control device is designed to perform multiple functions: it calculates cutting time for different arrangement angles, determines the optimal angle, controls the pattern rotation, and manages the coordinated movement of the cutting blade and object. This multi-functionality reduces the need for separate control systems while maintaining cutting efficiency
Solution Approach 2:
The system automatically calculates and determines the optimal arrangement angle without requiring manual intervention. The control device self-manages the angle selection and coordination of movements based on pre-calculated cutting times, reducing operational complexity while maintaining high cutting efficiency

AI summary
A cutting apparatus includes a moving device configured to move a cutting blade and an object in a first direction and in a second direction differing from the first direction, relative to each other and a control device configured to cause the apparatus to calculate first cutting time lengths required to cut a pattern at a plurality of arrangement angles when an arrangement angle of the pattern relative to the first or second direction is changed by a first unit angle, determine one of the arrangement angles, which is shortest with respect to the first cutting time length or not more than a first threshold, and control the moving device so that the movement of the cutting blade in the first direction and the movement of the object in the second direction are simultaneously executed, with a result that the pattern is cut at the determined arrangement angle.
