Machine Tool Window Coolant Protection Based on Operator Presence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In machine tool systems, the apparatus for clearing droplets of cutting fluid from the window is constantly operating, leading to unnecessary energy consumption as the frequency of operator visual checks decreases with automation.
Innovation Solution
A machine tool control system that includes a coolant protection unit, an operator sensor, and a visibility control unit, which switches the coolant protection unit's state based on the presence of the operator, thereby reducing energy consumption by only activating the unit when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the coolant protection unit operates constantly to clear cutting fluid droplets from the window, then visibility is maintained, but energy consumption increases
Solution Approach 1:
The coolant protection unit operates periodically rather than continuously. The control unit activates the coolant protection unit based on detection signals from the operator detection unit, creating an on-demand periodic operation pattern that maintains visibility only when operators are present to observe through the window.
Solution Approach 2:
The system uses the operator detection unit to automatically determine when cooling protection is needed, eliminating the need for constant operation. The control unit self-regulates the coolant protection unit based on detected operator presence, making the system adaptive to actual usage conditions.
2Object-affected harmful factors
If the coolant protection unit operates constantly, then cutting fluid droplets are cleared from the window, but energy is wasted when operators are not present
Solution Approach 1:
The operator detection unit provides feedback signals to the control unit about operator presence. The control unit uses this feedback to determine whether to activate the coolant protection unit, creating a closed-loop control system that prevents energy waste by operating only when operators are present.
Solution Approach 2:
The operation state of the coolant protection unit changes dynamically based on operator presence. The system transitions between active and inactive states according to real-time detection results, making the energy consumption adaptive rather than static.

AI summary
Disclosed is a machine tool including: a cover that encloses a processing space in which a workpiece is processed and has a window portion for visual inspection of the processing space from outside; a machining processing unit provided in the processing space; an operation panel for inputting instructions to the machining processing unit, the operation panel being provided outside of the cover; and a cooling system for cooling the machining processing unit, wherein the cooling system includes: a coolant supply unit for supplying a coolant into the processing space; a coolant protection unit that operates to limit adhesion of the coolant to the window portion; and a control unit that switches a state of the coolant protection unit based on a result of detection performed by a sensor for detecting an operator present around the cover. With this machine tool, waste of energy can be suppressed.
