Inspection Master With Oblique References for Five-Axis Accuracy Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current inspection masters are inadequate for performing accuracy inspections on five-axis processing machines and contact type three-dimensional measuring machines, as they cannot measure axes obliquely, limiting their ability to assess the rotation and turning axes effectively.
Innovation Solution
The development of an inspection master with upper-surface and peripheral-surface oblique reference portions, featuring obliquely opened reference holes and a reference ball, allows for axis measurements of rotation and turning axes, enabling accurate inspections of five-axis processing machines by allowing contact elements to interact with these features while the master is rotated or turned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If reference holes are opened only vertically or laterally on the inspection master, then measurement of three-axis directions is enabled, but measurement in oblique directions (rotation and turning axes) cannot be performed
Solution Approach 1:
The patent introduces oblique reference portions with reference holes opened in oblique directions (not only vertically or laterally). This adds a new dimensional aspect to the measurement capabilities, enabling the inspection master to measure rotation and turning axes of five-axis processing machines while maintaining compatibility with three-axis measurements
2Adaptability or versatility
If the inspection master is designed with only vertical and lateral reference holes, then the structure remains simple, but it cannot perform accuracy inspection for five-axis processing machines
Solution Approach 1:
The inspection master is designed with both traditional vertical/lateral reference portions and new oblique reference portions. This multi-functional design allows a single inspection master to perform measurements for both three-axis and five-axis processing machines, achieving universality without compromising measurement accuracy

AI summary
In an inspection master, an upper-surface oblique reference portion opened obliquely upward is provided on an upper surface of a master main body including the upper surface and a peripheral surface. In an inspection master, a peripheral-surface oblique reference portion opened obliquely upward is provided on a peripheral surface of a master main body including an upper surface and the peripheral surface. In either of those cases, an upper-surface vertical reference portion opened vertically can be provided on the upper surface, and a peripheral-surface lateral reference portion opened laterally can be provided on the peripheral surface. Further, a reference ball for use in obtaining an inclination angle of the master main body inclined during accuracy inspection for a five-axis processing machine is provided at a center portion of the upper surface.
