Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the setting values for rapid traverse, cutting feed and acceleration/deceleration are lowered for all machines, then vibrations are reduced and high-precision machining is protected, but overall work efficiency decreases
Solution Approach 1:
The system applies different operational restrictions to different machines based on their individual correlation with vibration generation. Instead of uniformly lowering settings for all machines, the analyzing unit identifies which specific machines have high correlation with vibration that affects precision, and the operation plan making unit creates targeted restrictions only for those machines. This localized approach protects high-precision machining while maintaining efficiency of non-problematic machines.
Solution Approach 2:
The system dynamically adjusts operational parameters (rapid traverse, cutting feed, acceleration/deceleration) based on analyzed correlation data. The operation plan making unit modifies these parameters selectively for specific machines during high-precision machining periods, rather than maintaining fixed low settings for all machines. This allows parameter optimization that balances precision protection with efficiency maintenance.
2Manufacturing precision
If the layout of industrial machines is changed to separate high-precision machines from other machines, then vibration transmission is reduced, but reconfiguration becomes troublesome and machine versatility decreases
Solution Approach 1:
The system replaces the mechanical solution of physical separation with an information-based control system. The analyzing unit collects and analyzes operational data to identify vibration correlations, and the operation plan making unit generates appropriate restrictions. This substitutes the need for physical layout changes with intelligent operational management, maintaining machine versatility while protecting precision machining.
3Manufacturing precision
If the layout of industrial machines is changed to separate high-precision machines from other machines, then vibration transmission is reduced, but machine versatility and overall machining efficiency decrease
Solution Approach 1:
The system implements dynamic operational restrictions that adapt to actual machining conditions. The analyzing unit continuously monitors the operational state of machines, and the operation plan making unit adjusts restrictions in real-time based on whether high-precision machining is actively occurring. This allows machines to operate at full capability when precision machining is not in progress, maintaining versatility while protecting precision work when needed.

AI summary
A managing apparatus includes: a data collecting unit that collects at least quality information on a workpiece having been machined by a first machine tool and operational information on other machine, an analyzing unit that performs an analysis for determining correlation between the quality information on a workpiece having been machined by the first machine tool and the operational information on the other machine, an operation plan making unit that makes an operation plan, based on the correlation determined by the analyzing unit, for imposing a restriction on an operation of the other machine to reduce vibrations to be transmitted to the first machine tool during high-precision machining performed by the first machine tool, and an operation instruction providing unit that provides an operation instruction to the other machine based on the operation plan made by the operation plan making unit.
