3D Model Optimization for Machine Interference Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current machine interference check technologies require unnecessary processing and increased costs due to the inclusion of all structures in interference checks, even though not all structures interfere, and creating three-dimensional model data specifically for interference checks is cumbersome and redundant.
Innovation Solution
An information processing device that optimizes three-dimensional model data for machine interference checks by selecting only relevant structures for interference check processing, using a check object selection unit and a model creating unit to generate data specifically for interference checks, thereby reducing processing load and eliminating unnecessary processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all structures are included in interference check objects, then interference check completeness is improved, but processing load and calculation amount increase
Solution Approach 1:
The patent extracts only the necessary structures (workpiece, tool, table, and clamps) from the complete machine tool structure for interference check. The check object selection unit identifies and selects only those structures that can actually interfere with each other during machining, excluding unnecessary components. This extraction principle reduces the number of check objects while maintaining interference detection completeness.
Solution Approach 2:
The patent segments the interference check process into two main functions: a check object selection unit that identifies relevant structures, and a model creating unit that generates three-dimensional models only for selected objects. This segmentation allows the system to focus computational resources on essential structures rather than processing all machine components uniformly.
2Measurement precision
If three-dimensional model data is created specifically for interference check, then interference check accuracy is improved, but data management complexity and cost increase
Solution Approach 1:
The patent makes the three-dimensional model data serve multiple functions: it is used both for interference checking and for generating machining instructions. The model creating unit generates models that are optimized for interference detection while reusing the same data for machining operations, eliminating the need for separate data management systems and reducing overall complexity.
Solution Approach 2:
The patent creates simplified three-dimensional models that are copies of the actual machine structures but optimized specifically for interference detection purposes. These copied models retain the essential geometric features needed for interference checking while being computationally more efficient, and they can be generated on-demand without duplicating the entire design data management system.

AI summary
An information processing device controls operation trouble or a calculation amount related to a machine interference check by automatically creating a three-dimensional model optimal for the machine interference check. The information processing device optimizes, for the interference check, three-dimensional model data of a machine including a plurality of structures. The information processing device includes a check object selection unit that performs selection among the structures, and a model creating unit that creates three-dimensional model data for an interference check which data includes the selected structure. Since the information processing device can generate three-dimensional model data optimized for an interference check, there is no trouble for a user to create new three-dimensional model data by himself/herself, and a simple and effective interference check can be realized.
