Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sizing methods for stiff plates, such as those used in forming worktops, fail to accurately account for varying thicknesses and shape defects, leading to irregularities and discontinuities in the joint areas when plates are placed alongside.
Innovation Solution
A method and machining centre using feeler means, such as mechanical or electronic sensors, to detect points on opposite faces of plates, calculating sizing values based on these detections, and removing material to ensure uniform thickness across the joint area, even with different thicknesses and shape defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional sizing methods are used to machine plates, then the machining process is simple, but the precision of thickness calibration is insufficient when plates have different thicknesses and shape defects
Solution Approach 1:
The patent transitions from single-point thickness detection to multi-point three-dimensional surface detection. By detecting at least four points on each plate (including opposite faces), the system creates a comprehensive 3D model of plate geometry, enabling accurate identification and compensation of shape defects like bending and warping, thereby achieving high precision thickness calibration.
Solution Approach 2:
The patent replaces traditional mechanical contact measurement methods with a dual-face detection system that uses coordinated sensing (mechanical or electronic feelers) to detect points on both upper and lower faces simultaneously. This substitution enables more accurate thickness measurement by directly comparing opposite faces, compensating for plate irregularities and achieving superior calibration precision.
2Manufacturing precision
If plates with different thicknesses and shape defects are placed alongside to form a worktop, then material utilization is improved, but the joint area exhibits irregularities and discontinuities
Solution Approach 1:
The patent performs preliminary detection and calculation of sizing values for all plates before the actual machining operation. By detecting at least four points on each plate and calculating the required material removal in advance, the system prepares a comprehensive machining plan that ensures perfect joint area regularity when plates are assembled, eliminating visible and tactile irregularities.
Solution Approach 2:
The patent applies differential sizing to different regions of plates based on local thickness variations and shape defects. By detecting multiple points across the plate surface and calculating specific sizing values for each plate's unique geometry, the system ensures that each plate is machined to its optimal dimensions, achieving uniform joint areas even when starting with plates of varying thicknesses and defects.
3Measurement precision
If multiple points on opposite faces of plates are detected to calculate sizing values, then the sizing precision is improved, but the detection time and process complexity increase
Solution Approach 1:
The patent implements continuous detection of multiple points on opposite faces of plates in a coordinated sequence. The detection system moves smoothly across the plate surfaces, collecting data at multiple locations without interruption, and the control unit continuously processes this data to calculate sizing values. This continuous operation minimizes detection time while maintaining high measurement precision through comprehensive multi-point sampling.

AI summary
A method and a machining centre are disclosed for machining plates made of marble, granite, ceramics, quartz or the like, in which a point on an upper face of a first plate, a point on the lower face of the first plate, a point on an upper face of a second plate and a point on the lower face of the second plate is detected, and in which, in a portion of the lower face of at least one of the two plates, a thickness of material is removed that is equal to a sizing value calculated on the basis of the aforesaid detection of points, so that, when the two plates are placed alongside to form a worktop, the joint area thereof is regular.
