Pivot Milling Cutouts in Sheet Workpieces to Reduce Offcuts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machining devices for plate-shaped workpieces result in increased offcuts and additional work steps due to the need for large cutouts for drilling units, especially at greater drilling depths, which complicates the machining process.
Innovation Solution
A method and device that utilize a machining tool, such as a milling tool, to introduce a cutout or groove into the workpiece by performing a pivoting movement within a separating region, allowing for reduced offcuts and work steps by enabling the machining tool to have a longer length than the width of the separating region, and allowing for adjustable angles and shapes of the cutout.

Engineering Contradiction Analysis
1Length of moving object
If large cutouts are introduced into the workpiece for drilling units to accommodate greater drilling depths, then drilling capability is improved, but material waste increases and additional work steps are required
Solution Approach 1:
The invention divides the workpiece into multiple partial workpieces by introducing separating regions before performing horizontal machining. This segmentation allows the drilling unit to access narrow surfaces of individual partial workpieces through smaller cutouts rather than requiring large cutouts in the original large workpiece, thereby reducing material waste while maintaining drilling capability at required depths
Solution Approach 2:
The invention performs preliminary horizontal machining and introduces separating regions into the workpiece before the main drilling operation. By preparing the workpiece structure in advance with separating regions and smaller cutouts, the drilling unit can subsequently access narrow surfaces efficiently without requiring excessive material removal, thus reducing material waste while enabling deep drilling
2Length of moving object
If large cutouts are introduced into the workpiece for drilling units, then drilling capability is improved, but the number of work steps increases
Solution Approach 1:
The workpiece is segmented into partial workpieces with separating regions introduced beforehand. This allows the drilling unit to perform horizontal machining on narrow surfaces of individual partial workpieces through smaller cutouts, consolidating multiple operations into a more streamlined process that reduces the total number of work steps compared to machining the entire large workpiece with large cutouts
3Loss of substance
If the separating region width is reduced to minimize offcuts, then material waste is reduced, but the machining tool must be positioned precisely within the narrow separating region
Solution Approach 1:
The invention employs a pivoting movement mechanism that allows the machining tool to dynamically adjust its position and orientation within the narrow separating region. The tool can pivot between a starting position aligned with the separating region and a machining position where it performs the pivoting movement to introduce the cutout. This dynamic positioning capability enables precise tool placement in narrow separating regions while maintaining the ability to perform effective machining operations
