Solution Overview

Problem

Computer-numerically-controlled (CNC) machines face challenges in accurately machining complex designs due to limitations in image processing and material recognition, particularly with laser cutters/engravers, which require precise control of electromagnetic radiation and are sensitive to material properties and operational conditions.

Innovation Solution

A method is developed to create an image file from camera-captured images within a CNC machine, generating a preview with overlaid cuts, allowing for digital correction and enhancement, and converting electronic images into machine instructions for precise material processing, utilizing camera systems for real-time image analysis and correction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional manufacturing techniques like moldings and manual assembly are used, then device complexity and operational simplicity are maintained, but manufacturing precision and detail level are insufficient

Engineering Contradiction:
Improvedetail levelVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual assembly and traditional mechanical manufacturing techniques with an automated CNC machine system that uses computer files and runtime interpretation to control machining operations. This substitution enables significantly higher manufacturing precision and detail levels while managing system complexity through software-based control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If CNC machines operate based on detailed computer files and runtime interpretation, then manufacturing precision is improved, but ease of operation and setup time are reduced

Engineering Contradiction:
ImproveprecisionVSAvoidoperational simplicity
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent applies preliminary action by pre-defining machining parameters, cut paths, and operational instructions in computer files before actual machining begins. The system interprets these pre-prepared instructions at runtime, enabling precise control while simplifying operation since users only need to load and execute pre-configured files rather than manually program each operation.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If laser cutters/engravers process materials with precise electromagnetic radiation control, then manufacturing precision is improved, but sensitivity to material properties and operational conditions creates reliability challenges

Engineering Contradiction:
Improvecut accuracyVSAvoidprocess stability
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent implements feedback mechanisms where the CNC machine system monitors and adjusts operational parameters based on material properties and processing conditions. The system uses computer files that contain material-specific parameters and adjusts electromagnetic radiation control in real-time during machining, maintaining precision while compensating for variations in material properties and environmental conditions.

Inventive Principle:
Principle #23Feedback

AI summary

A method may include generating, by a camera having a view of an interior portion of a computer-numerically-controlled machine, an image comprising a pattern. The image can be transformed into a set of machine instructions for controlling the computer-numerically-controlled machine to effect a change in a material. The change can correspond to at least a portion of the pattern. At least one machine instruction from the set of machine instructions can be executed to control the computer-numerically-controlled machine to effect at least a portion of the change. The execution can include operating, in accordance with the at least one machine instruction, a tool coupled with the computer-numerically-controlled machine. The tool can be configured to effect the change on the material. Related systems and articles of manufacture, including computer program products, are also provided.
