Numerical Control Apparatus Compatibility Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing numerical control apparatuses for machine tools lack an efficient method to determine compatibility between machine tools and machining programs, leading to potential interference and inaccurate machining results.
Innovation Solution
A numerical control apparatus that stores unique information about the machine tool, operator, and tools, and checks this information against incidental information in the machining program, only executing the program if it matches, and generates an alarm if it does not, ensuring compatibility and preventing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If unique information checking is implemented to ensure machine tool and program compatibility, then machining accuracy and safety are improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by checking compatibility information before the machining program is executed. The determination part verifies whether the incidental information in the received program matches the unique information stored in the machine tool or control apparatus, preventing incompatible programs from running and thus ensuring machining accuracy without requiring complex real-time monitoring systems
Solution Approach 2:
The patent implements feedback through the alarm generation part that notifies operators when compatibility checks fail. This feedback mechanism ensures that incompatible programs are identified and corrected before execution, maintaining machining accuracy while using a relatively simple system architecture
2Reliability
If comprehensive unique information is stored and checked for every program, then reliability is improved, but storage capacity requirements increase
Solution Approach 1:
The patent extracts only the essential compatibility information needed for verification and stores it as compact unique information (such as identification numbers or codes) rather than storing complete program details or extensive machine specifications. This extraction approach maintains reliability by preserving the critical matching elements while significantly reducing storage capacity requirements
Solution Approach 2:
The patent transforms complex compatibility verification requirements into simplified parameter comparisons by converting machine tool characteristics and program requirements into comparable unique information parameters. This parameter transformation enables reliable compatibility checking using minimal storage space, as only the essential identifying parameters need to be stored and compared

AI summary
A numerical control apparatus which enables a numerical control apparatus for a machine tool suitable for executing a particular machining program to selectively execute the machining program. The numerical control apparatus includes a storage that stores unique information; a receiving part that receives a machining program including incidental information; a determination part that checks the incidental information included in the machining program received by the receiving part with the unique information stored in the storage, and determines whether information matching the unique information is included in the incidental information; and a machine controller that executes the machining program received by the receiving part to control the machine tool only when it is determined that information matching the unique information is included in the incidental information.
