Composite Beam Tool Measurement for Rotary Cutting Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring rotating tools in numerical machine tools cannot simultaneously measure different dimensioned structures efficiently, requiring separate measurements for cutting length and radius, which increases measurement time and reduces precision.
Innovation Solution
A device using a composite measuring beam composed of multiple beams with adjustable properties, such as diameter and polarization, allows for simultaneous measurement of tool properties like circumference and cutting lengths by adapting beam characteristics in real-time, minimizing necessary tool movement and measurement time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single measuring beam is used to measure tool properties, then the device complexity is low, but the measurement precision and ability to measure different dimensioned structures simultaneously is insufficient
Solution Approach 1:
The measuring beam is segmented into multiple beams with different diameters (first measuring beam with larger diameter, second measuring beam with smaller diameter). Each beam segment is optimized for measuring specific tool structures - the larger beam measures overall tool circumference while the smaller beam measures cutting edge details, enabling simultaneous precise measurement of different dimensioned structures.
Solution Approach 2:
The measurement system transitions from a single-dimensional (single beam diameter) approach to a multi-dimensional approach by combining measuring beams with different diameters. This dimensional diversification allows the system to capture both large-scale tool geometry and fine cutting edge features simultaneously, resolving the limitation of single-beam measurements.
2Productivity
If separate measurements are performed for cutting length and radius, then the measurement accuracy for each property can be optimized, but the measurement time increases
Solution Approach 1:
Multiple measuring beams with different diameters are merged into a single composite measuring beam system. This combined beam structure enables simultaneous measurement of both tool radius (using the larger diameter beam) and cutting length (using the smaller diameter beam) in one operation, achieving both high productivity and maintained measurement accuracy.
Solution Approach 2:
The composite measuring beam system enables continuous simultaneous measurement of multiple tool properties (radius, cutting length, circumference) during a single tool rotation or positioning event. This eliminates the need for sequential separate measurements, maintaining continuous useful action and significantly reducing total measurement time while preserving accuracy through the multi-beam configuration.
3Adaptability or versatility
If the measuring beam diameter is fixed, then the device complexity is low, but the adaptability to measure different tool structures is limited
Solution Approach 1:
The composite measuring beam system achieves universality by integrating multiple beams with different diameters into a single measurement apparatus. This multi-functional beam configuration can adaptively measure various tool structures (large-diameter tools, small cutting edges, different geometries) simultaneously, providing universal measurement capability without requiring separate specialized devices for each tool type.
