Tool Path Adjustment for Insufficient Blade Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool path generation methods for machining are inefficient when the effective blade length of a tool is insufficient, leading to time-consuming recalculations and potential interruptions in machining due to overlooked blade length limitations.
Innovation Solution
A method and device that judge the sufficiency of the tool's blade length, estimate insufficient portions, generate moved tool paths to accommodate the effective blade length, and create auxiliary paths to complete machining, ensuring the tool path is adjusted to prevent interruptions and optimize machining efficiency.

Engineering Contradiction Analysis
1Reliability
If a user manually determines excess portions and generates tool paths by repeating calculations, then the tool path can be adjusted for blade length, but the time and effort required increases significantly
Solution Approach 1:
The system automatically judges whether the effective blade length is insufficient and generates moved tool paths without requiring user intervention. The control device performs self-service by autonomously detecting blade length issues and recalculating tool paths, eliminating the need for users to manually determine excess portions and repeat calculations.
Solution Approach 2:
The system implements feedback by automatically judging blade length sufficiency based on the generated tool path and workpiece shape. When insufficiency is detected, the system feeds back this information and automatically generates corrected moved tool paths, creating a closed-loop system that continuously verifies and adjusts tool paths without user input.
2Productivity
If the effective blade length is not checked in advance, then tool path generation is faster, but machining interruptions may occur during operation
Solution Approach 1:
The system performs preliminary action by automatically judging whether the effective blade length is insufficient before machining operations begin. The control device calculates moved tool paths in advance based on the workpiece shape and tool specifications, ensuring that blade length issues are resolved before machining starts, thereby preventing interruptions during operation.
3Manufacturing precision
If multiple recalculations are performed to adjust tool paths for blade length, then machining accuracy is maintained, but the overall machining efficiency decreases
Solution Approach 1:
The system automatically performs the necessary recalculations and generates moved tool paths without requiring multiple user interventions. The control device self-services by continuously monitoring blade length sufficiency and autonomously generating corrected tool paths, maintaining machining accuracy while minimizing the time lost to recalculations.

AI summary
A tool path generating device for generating a machining program is provided with a determining unit which determines whether or not the effective cutting length of a tool would be insufficient if machining were performed using a first tool path, and an estimating unit which estimates a section of insufficiency, being the section in which the effective cutting length of the tool is insufficient. The tool path generating device is provided with a post-move travel path generating unit which generates a post-move tool path in which the path corresponding to the section of insufficiency has been moved relative to the first tool path to a path whereby the section of insufficiency can be machined using the section of the tool within the effective cutting length, and an auxiliary path generating unit which generates an auxiliary tool path for machining the uncut section remaining in the workpiece.
