Panel Dividing System Edge Trimming and Sawing Sequence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for dividing workpieces into strips and then parts are inefficient due to the need for separate trimming processes along multiple cutting lines, leading to increased time and material waste.
Innovation Solution
A method where the workpiece is trimmed along a seam line parallel to the second cutting line before being sawn along the first cutting line, eliminating the need for subsequent trimming processes on individual workpiece strips during the second cutting line operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If trimming processes are carried out together with first and second cutting lines in separate process sections, then each workpiece strip can be trimmed individually, but the total processing time increases significantly
Solution Approach 1:
The invention performs a preliminary trimming action along a seam line parallel to the second cutting lines before the workpiece is sawn into strips. This preliminary trimming creates a straight and clean outer edge on the entire workpiece at once, so that when the workpiece is subsequently divided into strips, all strips automatically inherit this trimmed edge. This eliminates the need for separate trimming operations on each individual strip, thereby resolving the contradiction between achieving good edge quality and maintaining high processing speed.
2Manufacturing precision
If multiple separate trimming processes are performed on each workpiece strip, then clean edges are achieved on all strips, but the number of processing steps increases
Solution Approach 1:
The invention merges multiple separate trimming operations into a single trimming process. Instead of trimming each workpiece strip individually along with the second cutting lines, the method combines all trimming needs into one preliminary trimming operation along a seam line before sawing. This single trimming action produces a clean edge that serves all subsequent strips, thereby reducing the number of trimming operations from multiple to one and simplifying the overall process.
3Manufacturing precision
If trimming is performed after sawing workpiece into strips, then each strip can be precisely trimmed to final dimensions, but material waste increases due to multiple cutting passes
Solution Approach 1:
The invention performs the trimming action in advance before the workpiece is divided into strips. By trimming along a seam line parallel to the second cutting lines before sawing, the method establishes the final edge geometry early in the process. This preliminary action ensures that when strips are cut, they already have the correct dimensions and clean edges, eliminating the need for additional material removal operations that would otherwise be required on each strip, thereby reducing material waste.
