Turning Tool Layout for In-Process Inner Diameter Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing turning tools face difficulties in imaging the inner diameter surface of a machined hole during machining due to the separate placement of the camera and lack of illumination, making it challenging to check the machined surface effectively.
Innovation Solution
A turning tool design that integrates a camera and illumination device within the tool main body, allowing the camera to image the machined surface from a radial direction orthogonal to the tool axis, with the camera and cutting insert positioned on opposite radial sides to prevent chip interference and enhance imaging accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the camera is disposed outside the cutting device, then the structure is simple, but it cannot image the inner diameter surface of the hole during machining
Solution Approach 1:
The camera is integrated into the tool main body of the cutting device, merging the imaging function with the cutting function. This allows the camera to be positioned inside the hole during machining and image the inner diameter surface, resolving the contradiction between structural simplicity and imaging capability.
2Reliability
If the camera and illumination device are installed separately from the tool main body, then they can function independently, but it requires additional space and increases device complexity
Solution Approach 1:
Both the camera and illumination device are integrated into the tool main body, combining multiple functions within a single structure. This eliminates the need for separate installation spaces while maintaining the independent functionality of each component.
Solution Approach 2:
The tool main body serves multiple functions: it holds the cutting insert, houses the camera, and accommodates the illumination device. This multi-functionality reduces the overall space requirement while maintaining independent operation of each component.
3Device complexity
If the base and camera are disposed on the same radial side, then the structure is compact, but chips generated by cutting can reach and damage the camera
Solution Approach 1:
The base and camera are disposed on opposite radial sides, creating an asymmetric layout that uses the tool axis as a barrier. This positioning prevents chips generated during cutting from reaching the camera while maintaining structural compactness through optimized space utilization.

AI summary
A turning tool according to the present invention includes a tool main body that extends along a tool axis (J) and that has a base at a tip portion on one side in an axial direction (Dj) along the tool axis (J), a cutting insert detachably attached to the base, and a camera provided in the tool main body and configured to image a machined surface of a work material cut by the cutting insert, in which the camera is disposed to image an outer side in a radial direction (Dr) of the tool main body intersecting with the axial direction (Dj).
