Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CNC machining processes are complex and time-consuming, requiring skilled operators to adjust numerous parameters, leading to inefficiencies and material waste, as they struggle to achieve precise cuts for three-dimensional shapes without duplicating workshop functionality.
Innovation Solution
A method and system using visual indicia or glyphs on a guide to direct a cutting tool, where the guide's glyphs are used to orient the tool for precise cutting based on a specific three-dimensional model, allowing for the cutting of workpieces without the guide's presence after initial alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional CNC machining processes are used with multiple parameters and work coordinate offsets, then manufacturing precision can be achieved, but device complexity and ease of operation deteriorate due to the large number of parameters requiring adjustment
Solution Approach 1:
The patent uses a two-dimensional representation (copy) of the three-dimensional model displayed on the worktable to define the cutting path. Instead of programming complex 3D toolpaths with multiple parameters, the system projects a 2D image that directly guides the cutting tool, simplifying the control system while maintaining precision.
Solution Approach 2:
The patent replaces the traditional mechanical parameter-adjustment system with an optical/visual system. The 2D representation displayed on the worktable serves as a visual guide for the cutting tool, substituting complex mechanical coordinate systems and offset adjustments with a straightforward visual tracking approach.
2Manufacturing precision
If traditional CNC machining processes are used with work coordinate offsets and material positioning, then manufacturing precision can be achieved, but ease of operation deteriorates due to time-consuming alignment and fixturing steps
Solution Approach 1:
The system performs preliminary action by displaying the complete 2D representation of the cutting path on the worktable before cutting begins. This allows the operator to visualize the entire cutting process in advance and position the material correctly without iterative alignment adjustments, saving time while ensuring precision.
Solution Approach 2:
The 2D representation displayed on the worktable serves as an intermediary between the digital model and the physical cutting process. It provides a visual bridge that guides the cutting tool's movement without requiring complex coordinate transformations or offset calculations, simplifying the operator's task while maintaining accuracy.
3Manufacturing precision
If traditional CNC machining processes are used with test passes and parameter adjustments, then manufacturing precision can be achieved, but loss of time and loss of substance increase due to multiple test runs and material waste
Solution Approach 1:
The system uses feedback by continuously monitoring the cutting tool's position relative to the displayed 2D representation on the worktable. This real-time visual feedback ensures the tool follows the correct path without requiring test passes, reducing setup time while maintaining precision through automated position verification.
4Manufacturing precision
If traditional CNC machining processes are used with work coordinate offsets and material positioning, then manufacturing precision can be achieved, but ease of operation deteriorates due to skilled operator time requirements
Solution Approach 1:
The system performs self-service by automatically displaying the correct 2D representation on the worktable and guiding the cutting tool's movement. This eliminates the need for operators to manually calculate and adjust work coordinate offsets, making the process accessible to less skilled operators while maintaining precision through automated visual guidance.

AI summary
Cutting a workpiece using a cutting tool associated with a system, whereby the system includes a guide having a first glyph and second glyph. The first and second glyphs are both visible on a single side of the guide. The guide is associated with a specific three-dimensional model of a plurality of three-dimensional models. The system further includes an input mechanism, configured to receive a location of the first glyph and of the second glyph, relative to the cutting tool. The system further includes a control system, functionally associated with the input mechanism and with the cutting tool. The control system is configured to direct the cutting tool to cut a version of the specific three-dimensional model into the workpiece at a location, such as at least partially between the locations of the first glyph and the second glyph, which locations were received by said input mechanism.
