Flat Workpiece Segmentation via Joint Transverse and Longitudinal Cuts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for dividing plate-shaped workpieces are inefficient, requiring multiple cutting processes and increasing the length of the dividing line, which complicates the process and reduces productivity.
Innovation Solution
The method involves performing a transverse dividing cut and a longitudinal dividing cut of the second order in a joint cutting process, using a circular saw blade on a saw carriage, which reduces the number of cutting processes and allows for efficient separation of waste and product pieces, enabling precise alignment and flexible handling of workpieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional multi-step cutting processes are used to divide workpieces, then complete division into strips and pieces is achieved, but the number of cutting operations increases and productivity decreases
Solution Approach 1:
The patent combines the transverse dividing cut and the second-order longitudinal dividing cut into a single cutting operation. The saw blade performs both cutting actions simultaneously on the workpiece, eliminating the need for separate cutting steps and thereby increasing productivity while maintaining complete workpiece division.
Solution Approach 2:
The cutting process continues uninterrupted by performing multiple division cuts in one operation. The saw blade moves continuously along the workpiece, executing transverse and longitudinal divisions without stopping or repositioning the workpiece between cuts, thus maintaining continuous useful action and improving efficiency.
2Manufacturing precision
If multiple separate cutting processes are performed, then thorough workpiece division is achieved, but the process complexity and time consumption increase
Solution Approach 1:
Multiple division operations are merged into one cutting pass. The saw blade executes both transverse and second-order longitudinal cuts during a single continuous movement, reducing the total time required while preserving the accuracy of each individual cut through proper positioning and guide mechanisms.
Solution Approach 2:
The workpiece is preliminarily positioned and secured on the support table before the cutting operation begins. Stop means are pre-adjusted to the required positions to ensure accurate cut locations. This preliminary preparation enables the saw blade to perform multiple divisions quickly and accurately without time-consuming repositioning during the cutting process.
3Manufacturing precision
If conventional cutting methods are used, then standard workpiece division is achieved, but waste piece handling becomes more difficult
Solution Approach 1:
The combined cutting operation produces waste pieces in a consolidated manner, with all waste sections generated during a single cutting pass being adjacent to each other. This makes waste piece removal easier as they can be cleared together in one operation rather than handling scattered waste from multiple separate cutting steps.
Solution Approach 2:
The multi-cut operation in a single pass converts the potential harm of complex waste handling into a benefit by producing waste pieces that are naturally grouped together. The combined cutting paths ensure that waste sections from different cuts are adjacent, transforming a handling difficulty into a simplified removal process.
