Machine Tool Coolant Control Around Discharge-Inhibited Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In machine tools, there is a portion known as the discharge inhibited portion that may fail due to coolant adhesion, and existing techniques do not effectively prevent coolant adhesion to this portion.
Innovation Solution
A machine tool system is developed with a first discharge unit for coolant, a portion to which coolant should not be discharged, a first drive unit for adjusting the relative position between the discharge unit and the portion, and a control unit that recognizes the position of the portion and controls the coolant discharge to prevent it from reaching the portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If coolant is discharged to remove chips, then chip removal efficiency is improved, but coolant may adhere to discharge inhibited portion causing machine tool failure
Solution Approach 1:
The discharge port is made movable rather than fixed, allowing it to dynamically adjust its position and discharge direction based on the real-time location of the discharge inhibited portion. The second drive unit enables the discharge port to move to different angular positions, transforming a static cooling system into a dynamic one that can adapt to prevent coolant adhesion to sensitive components while maintaining effective chip removal.
Solution Approach 2:
The system changes the discharge parameters (direction and position) of the coolant based on the recognized position of the discharge inhibited portion. By adjusting the discharge port's angular position through the second drive unit, the system modifies the coolant flow parameters to avoid the inhibited portion while maintaining effective chip removal capability.
2Device complexity
If discharge port position is fixed, then device complexity is reduced, but ability to prevent coolant adhesion to discharge inhibited portion is insufficient
Solution Approach 1:
The discharge port is made movable rather than fixed, allowing it to dynamically adjust its position and discharge direction based on the real-time location of the discharge inhibited portion. The second drive unit enables the discharge port to move to different angular positions, transforming a static cooling system into a dynamic one that can adapt to prevent coolant adhesion to sensitive components while maintaining effective chip removal.
Solution Approach 2:
The system uses a camera to recognize the position of the discharge inhibited portion and provides feedback to the control unit. Based on this feedback, the control unit adjusts the discharge port's position through the second drive unit, creating a closed-loop control system that continuously monitors and adjusts coolant discharge to prevent adhesion to the inhibited portion.

AI summary
A technique for preventing a coolant from adhering to a discharge inhibited portion is provided. A machine tool capable of machining a workpiece includes: a first discharge unit that discharges the coolant removing a chip of the workpiece; a portion inside the machine tool and to which the coolant should not be discharged; a first drive unit that changes a relative position between the first discharge unit and the portion; and a control unit that controls the machine tool. The control unit performs processing for recognizing a position in the machine tool of a moving object by the first drive unit between the first discharge unit and the portion, and processing for controlling the discharge of the coolant by the first discharge unit such that the coolant is not discharged to the portion based on the position recognized in the recognition processing.
