Rotating Body Surface Imaging Across Multiple Revolutions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to capture the surface image of a rapidly rotating body effectively due to limitations in camera frame rate and readout speed, making it difficult to obtain an accurate image of the surface during its use in a machine tool.
Innovation Solution
A machine tool method that distributes multiple images of a rotating body's surface over several revolutions, with each image angularly offset to cover up to 360 degrees, and optionally distributes these images across the camera's image recording surface during a single illumination period using a movable mirror arrangement or other means, allowing for high-speed surface recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a marking device is applied to the surface of a rotating body, then surface recording is achieved, but the marking device is damaged by impact with the rotating body surface
Solution Approach 1:
A transfer member is introduced as an intermediary between the marking device and the rotating body surface. The transfer member receives markings from the marking device and transfers them to the rotating body, preventing direct impact damage to the marking device while maintaining marking functionality
Solution Approach 2:
The marking is first created on the transfer member as a copy, then transferred to the rotating body surface. This indirect copying process protects the original marking device from direct contact and damage with the rotating body
2Productivity
If the rotating body surface is used as the recording medium, then direct surface marking is achieved, but contamination of the rotating body surface occurs
Solution Approach 1:
The transfer member serves as a mediator that carries the marking material to the rotating body surface without directly contaminating it. The marking is transferred through controlled contact, preventing unwanted contamination while maintaining marking efficiency
Solution Approach 2:
The marking process is segmented into two distinct steps: first creating the marking on the transfer member, then transferring it to the rotating body. This separation prevents contamination during the marking creation phase while maintaining efficiency through the transfer mechanism
3Device complexity
If conventional marking devices are used on rotating bodies, then simple marking is achieved, but reliable data recording is not possible due to surface damage and contamination
Solution Approach 1:
The transfer member acts as a reliable intermediary that ensures consistent marking transfer without the reliability issues of direct marking. It protects against surface damage and contamination while maintaining data recording integrity
Solution Approach 2:
The marking is preliminarily created on the transfer member before being applied to the rotating body. This preliminary action ensures the marking is established in a controlled environment, improving reliability before the transfer to the rotating body surface

AI summary
The invention relates to a method for surface recording comprising: rotating a body (1), more particularly a tool or workpiece, about an axis of rotation (2); and, during the rotation of the body (1), recording by means of a camera (3) and e.g. a mirror arrangement, a number of a >1 recordings (6), which are offset at an angle of rotation, wherein each recording (6) represents a different portion of a surface (13) of the body (1), wherein the a recordings (6) together represent an angle of rotation range m of up to 360° of the circumferential surface (13) and wherein the a recordings (6) are distributed over several rotations of the body (1).
