Cutting Apparatus Controller Adjusts Pressure for Thick Workpieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting apparatuses may perform incomplete cuts due to improper input of the number of cuts required for thick workpieces, leading to suboptimal cutting conditions.
Innovation Solution
A cutting apparatus equipped with a platen, attaching portion, moving mechanisms, pressure changer, and sensor, controlled by a controller that determines the appropriate cutting conditions based on the workpiece's thickness and pressure thresholds to ensure accurate and complete cuts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the number of cuts is manually input for thick workpieces, then the cutting process can be performed, but incomplete cuts may occur due to improper input
Solution Approach 1:
The cutting apparatus automatically determines the number of cuts required by detecting the workpiece thickness and calculating the appropriate cut count based on predetermined thickness ranges. This eliminates the need for manual input while ensuring accurate and complete cuts through self-determination of cutting parameters.
2Measurement precision
If the attaching portion moves to the target position, then precise cutting position is achieved, but the workpiece thickness may not be adequately considered
Solution Approach 1:
The system performs preliminary detection of workpiece thickness before the attaching portion moves to the target position. Based on the detected thickness, the controller predetermined the number of cuts and adjusts cutting parameters in advance, ensuring that both positioning accuracy and cutting quality are optimized for the specific workpiece thickness.
3Force
If pressure is increased to ensure complete cuts through thick workpieces, then cutting effectiveness improves, but the risk of improper pressure application increases
Solution Approach 1:
The controller dynamically adjusts cutting parameters including pressure magnitude and number of cuts based on the detected workpiece thickness. For thicker workpieces, the system increases pressure and/or the number of cutting passes, while for thinner workpieces, it reduces these parameters. This adaptive parameter adjustment ensures optimal cutting conditions for each specific workpiece, preventing both insufficient and excessive pressure application.

AI summary
A controller of a cutting apparatus specifies a target position of an attaching portion in a fifth direction and controls a second moving mechanism to move the attaching portion in a third direction. If the controller determines that the attaching portion has reached the target position, the controller executes cutting processing based on the obtained cutting data by controlling the second moving mechanism based on a pressure corresponding value achieved when the attaching portion is located at the target portion. If the controller determines that the pressure corresponding value has reached a pressure threshold, the controller executes the cutting processing by controlling the second moving mechanism based on the pressure corresponding value achieved when the attaching portion is located at a first particular position where the pressure corresponding value is equal to or lower than the pressure threshold value. The controller restarts controlling the second moving mechanism.
