Engineering Contradiction Analysis
1Productivity
If cutting volume calculation is integrated into machining programs to control peripheral devices, then resource utilization and machining efficiency are improved, but device complexity and programming complexity increase
Solution Approach 1:
The cutting volume calculation is performed in advance during the program generation phase, and the results are embedded into the machining program as additional information. This allows the numerical controller to directly use the pre-calculated cutting volume data to control peripheral devices without requiring complex real-time calculations during machining execution.
Solution Approach 2:
The patent introduces an intermediary program generation system that acts as a bridge between the CAD model and the numerical controller. This intermediary calculates cutting volume, generates control commands for peripheral devices, and embeds them in the machining program, thereby decoupling the complexity from the numerical controller itself.
2Measurement precision
If additional cutting information is added to machining programs, then control precision of peripheral devices is improved, but information processing complexity increases
Solution Approach 1:
The machining program is segmented to include distinct additional information fields for cutting volume and peripheral device control commands. This segmentation allows the numerical controller to process different types of information separately and efficiently, reducing overall processing complexity while maintaining high control precision.
Solution Approach 2:
The patent transforms geometric model data into calculated cutting volume parameters, which are then converted into specific control commands for peripheral devices. This parameter transformation chain simplifies the information processing by converting complex geometric relationships into straightforward control parameters.
