1Loss of time
If manual experimentation is used to determine workpiece alignment angle, then the alignment can be determined, but the process is time-consuming and does not achieve maximum time savings
Solution Approach 1:
The patent replaces manual mechanical experimentation with a computer-based simulation system. The control unit simulates different workpiece alignments and evaluates process variables to automatically determine the optimal alignment angle, eliminating time-consuming manual trial-and-error while maintaining ease of operation through automated software execution
Solution Approach 2:
The patent performs preliminary simulation and evaluation of different alignment options before actual machining begins. By pre-calculating the optimal alignment angle through virtual experimentation and storing the results, the system eliminates the need for time-consuming on-site adjustments and ensures maximum processing speed from the start
2Productivity
If multiple alignments are evaluated to find optimal alignment, then machining efficiency is improved, but computational effort and hardware requirements increase
Solution Approach 1:
The patent utilizes the existing control unit of the production machine to perform multiple functions: it not only controls the machining process but also simulates different workpiece alignments and evaluates process variables. This multi-functional approach allows comprehensive alignment optimization without adding specialized hardware, maintaining simplicity while improving productivity
Solution Approach 2:
The patent systematically varies alignment parameters (rotation angles, positioning coordinates) in the simulation to evaluate their impact on process variables. By changing these parameters virtually and identifying the optimal combination that maximizes machining efficiency, the system achieves high productivity without requiring complex hardware modifications
