Solution Overview
Problem
Existing methods for machining grooves in the underside of floor panels are inefficient and lack precision, particularly when cutting multiple parallel grooves with inclined inner walls, which affects the adhesive capacity and ventilation of the underfloor space.
Innovation Solution
The method employs a device with rotary machining units using axially separated profile disc milling cutters with varying diameters and an inclined spindle axis to cut parallel grooves, stabilized by lamellar transport assemblies and pressing transport assemblies, ensuring accurate and efficient machining of dovetail, half dovetail, or parallelogram grooves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional rotary cutting tools or planing tools are used to machine grooves in the underside of floor panels, then the machining process is simpler, but the efficiency is low and precision is poor when cutting multiple parallel grooves with inclined inner walls
Solution Approach 1:
The cutting head is divided into multiple axially separated disc milling cutters, each with a specific diameter and positioning. This segmentation allows simultaneous cutting of multiple parallel grooves with different depths and inclined inner walls in a single pass, dramatically improving productivity while maintaining precise geometric control through the structured arrangement of individual cutter elements
Solution Approach 2:
The invention transitions from conventional single-plane cutting to multi-dimensional cutting by arranging disc milling cutters at different axial positions and diameters. This dimensional arrangement enables the creation of grooves with inclined inner walls and varying depths simultaneously, achieving complex geometries that would require multiple sequential operations with simpler tools
2Manufacturing precision
If the floor panel is not secured during machining, then the setup is simpler, but the panel experiences uncontrolled position changes affecting machining precision
Solution Approach 1:
The retaining and pressing transport assemblies secure the floor panel in a fixed position before the cutting operation begins. This preliminary securing action prevents any uncontrolled position changes during machining, ensuring that the multiple parallel grooves are cut with precise positioning and dimensions relative to each other and to the panel edges
Solution Approach 2:
The retaining and pressing transport assemblies act as intermediary elements between the floor panel and the machining system. These assemblies provide stable support and positioning, mediating the interaction between the panel and cutting tools to maintain precise geometric relationships throughout the machining process
3Manufacturing precision
If conventional cutting methods are used, then the equipment is simpler, but vibrations occur reducing machining quality and causing surface damage
Solution Approach 1:
The retaining and pressing transport assemblies provide counterbalancing support that stabilizes the floor panel during the cutting operation. This counter-support system counteracts the forces and vibrations generated by the rotating disc milling cutters, preventing excessive panel movement and maintaining high surface finish quality on the groove walls and bottoms
Solution Approach 2:
The system incorporates dynamic stabilization through the coordinated operation of retaining and pressing transport assemblies that can adapt to the forces generated during cutting. This dynamic support system maintains optimal contact and positioning throughout the machining process, reducing vibrations and ensuring consistent machining quality
