Precision Machine Tool Imaging for Safe Machining Point Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In precision machining, operators face safety risks due to the need for visual observation of the machining point, which can result in exposure to chips and collisions with the machine.
Innovation Solution
A precision machine tool equipped with imaging devices attached to a moving mechanism, allowing the operator to observe the machining point remotely through captured images without changing the relative position of the imaging device to the tool support, ensuring safety by maintaining a distance from the machining area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator brings their face close to the machining point for visual observation, then the operator can directly observe the machining conditions, but the operator is exposed to safety risks such as chips getting in the eyes, head collisions with the machine, and unexpected contact with the tool
Solution Approach 1:
The patent introduces an imaging device as an intermediary between the operator and the machining point. The imaging device captures images of the machining point and transmits them to a display device, allowing the operator to observe machining conditions remotely without direct exposure to hazards. This mediator eliminates the need for the operator to be in close proximity to the machining point while maintaining full observational capability.
Solution Approach 2:
The imaging device creates a visual copy of the machining point by capturing images and transmitting them to the display device. The operator observes this copied visual information rather than the actual machining point, enabling safe remote monitoring. The copy preserves all necessary visual details for observation while removing the physical danger of being near the machining area.
2Object-affected harmful factors
If imaging devices are fixed to the tool support or moving mechanism to enable remote observation, then operator safety is improved, but the relative position between the imaging device and tool may change during movement
Solution Approach 1:
The imaging device is merged with the tool support or moving mechanism as an integrated unit. By fixing the imaging device to these moving components, the system ensures that the imaging device moves together with the tool, maintaining a stable relative position relationship. This integration allows the imaging device to follow the tool's movement while keeping the relative geometry constant, ensuring consistent image quality and observation angles throughout the machining process.

AI summary
A precision machine tool includes: a tool support for supporting a tool; a tool table serving as a moving mechanism capable of moving the tool support; and one or multiple imaging devices fixed to the tool support, the imaging devices each having an imaging unit configured to capture the image of a machining point on a workpiece machined by the tool.
