Machine Tool Spindle-Mounted Measuring Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool measuring devices on machine tools are prone to damage and soiling due to their fixed location on the machine table, restricting the clamping surface and increasing the risk of collision during processing operations.
Innovation Solution
The measuring device is temporarily positioned at a measuring point using spindle movements, allowing it to be removed after measurements, thus avoiding damage and soiling, and can be stored in a parking station or tool magazine for later use, with a standardization tool used for calibration before measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the measuring device is fixed on the machine table, then the measurement function is always available, but the clamping surface is restricted and the risk of collision and soiling increases
Solution Approach 1:
The measuring device is transformed from a static fixed installation to a dynamic movable component that can be positioned to the measuring point only when needed. The spindle serves as a moving carrier that transports the measuring device to the workpiece area, enabling the system to adapt its configuration based on operational requirements.
Solution Approach 2:
The spindle is assigned a dual function: its primary function for tool holding and processing, and a secondary function for transporting the measuring device. This multi-functionality eliminates the need for separate fixed installations while maintaining measurement capabilities.
2Reliability
If the measuring device is fixed on the machine table, then the measurement function is always available, but the risk of damage and soiling increases
Solution Approach 1:
By making the measuring device movable via the spindle, it can be dynamically positioned away from harmful processing zones when measurement is not required, reducing exposure to collision risks and soiling from machining operations.
Solution Approach 2:
The measuring device is extracted from the fixed machine table environment and relocated to the spindle, separating it from the harmful factors present during machining operations such as chips, coolant spray, and potential collisions.
3Device complexity
If the measuring device is moved by spindle movements, then no additional mechanical positioning units are needed, but the measuring device must be temporarily positioned and removed
Solution Approach 1:
The spindle's existing movement capabilities are utilized for dual purposes: tool processing operations and measuring device positioning. This eliminates the need for separate positioning mechanisms while maintaining measurement functionality through the spindle's inherent degrees of freedom.

AI summary
A method is proposed for measuring tools on a machine tool with a measuring device, wherein by means of a movement of a spindle of the machine tool the measuring device is temporarily positioned at a measuring point on the machine tool in order to carry out one or more measurements, the measuring point differing from a spindle mount. Furthermore, a measuring apparatus is proposed which is embodied in such a way that the measuring device can be positioned at a measuring point on the machine tool for a measuring operation by means of a spindle movement of a machine tool, said measuring point differing from a spindle mount.
