Stone Slab Layout Mirroring for Upside-Down CNC Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to accurately position and cut stone slabs upside down, as software programs like Slabsmith are designed for the top polished face and fail to effectively align the slab when the polished face is inverted, making precise cutting challenging.
Innovation Solution
A system involving an imaging device, controller, and CNC slab processing machine that uses adhered reference markers and laser projection to mirror-image the slab layout, allowing for accurate alignment and cutting of stone slabs when the polished face is down, utilizing a CNC machine with vacuum pods for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the slab is positioned upside down for cutting, then the cutting process can be performed, but accurate alignment and positioning become difficult or impossible using traditional software-based methods
Solution Approach 1:
The patent applies inversion by creating a mirror image of the slab layout when the slab is positioned upside down. The controller generates a mirror image of the digital slab layout file, allowing the cutting machine to accurately position and cut the slab in the inverted position by referencing the mirrored pattern rather than the original upright orientation.
Solution Approach 2:
The patent uses copying by creating a digital mirror image copy of the slab layout. This mirrored digital representation serves as a reference pattern that is projected onto the work surface, enabling accurate positioning and alignment of the upside-down slab without requiring direct visual reference to the original upright layout.
2Ease of operation
If traditional software programs are used for positioning, then the slab cut layout can be generated, but they fail to effectively align the slab when the polished face is inverted
Solution Approach 1:
The controller automatically generates a mirror image of the digital slab layout file when the slab is positioned upside down. This inversion of the layout pattern allows traditional software to effectively support upside-down positioning by adapting the reference pattern to match the inverted orientation, thereby maintaining positioning accuracy.
Solution Approach 2:
The system dynamically adapts the slab layout representation based on the slab's orientation. When the slab is positioned upside down, the controller automatically switches from displaying the original layout to displaying the mirror-imaged layout, making the positioning system flexible and adaptable to different slab orientations rather than being fixed to upright positioning only.
3Measurement precision
If the slab is cut in the normal position with polished face up, then positioning is accurate, but the cutting process cannot be performed when the polished face must be down
Solution Approach 1:
The patent enables cutting in both normal and inverted positions by implementing mirror imaging functionality. The controller generates a mirror image of the digital slab layout file specifically for upside-down positioning, allowing the system to maintain positioning accuracy regardless of whether the slab is cut with the polished face up or down, thereby providing cutting position flexibility.
Solution Approach 2:
The positioning system becomes universal by accommodating both upright and inverted slab positions. The controller can switch between displaying the original layout for normal positioning and the mirror-imaged layout for upside-down positioning, making the system versatile enough to handle different cutting requirements and slab orientations within a single workflow.

AI summary
A system processes a stone slab having a top polished face and bottom surface. An imaging device receives and displays a digital image of the top polished face of the slab. A controller overlays a slab cut layout on the digital image of the top polished face, generates a digital slab layout file containing digital data representative of the top polished face and its slab cut layout referenced to the top end of adhered reference markers, mirror images the digital slab layout file, and projects the mirror imaged locations of the reference markers to facilitate alignment of the bottom ends of the adhered laser markers with the respective projected reference marker locations when the slab is upside down for cutting in a slab cutting position.
