Slant Surface Tool for Fast Machining Tip Shape Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the shape of a machining tool's tip end are tedious and time-consuming, as they require repositioning a plate-shaped object to observe machining marks from different sides.
Innovation Solution
A determining tool with a flat slanting surface inclined at an angle of 30° to 60° is used, allowing the machining tool to cut through the surface while moving relative to the tool. The shape of the machining mark is then checked from the opposite side of the tool, eliminating the need for repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a plate-shaped object is used to determine the shape of the machining tool tip end by observing machining marks, then the shape can be determined, but the process becomes tedious and time-consuming due to the need to reposition the object multiple times
Solution Approach 1:
The invention transitions from observing machining marks on a flat plate surface (2D observation requiring repositioning) to projecting the mark shape onto a slanting surface that is inclined relative to the bottom surface. This dimensional change allows the camera to capture the entire mark shape in a single observation from above, eliminating the need for repositioning and significantly reducing determination time while maintaining measurement accuracy
2Productivity
If the machining tool is used to machine a workpiece, then the workpiece is processed, but the round tip end of the machining tool transfers its shape to the workpiece, making it impossible to machine the desired shape
Solution Approach 1:
The invention implements a preliminary determination step before actual machining operations. By using the determining tool with a slanting surface to check the machining tool tip end shape in advance, the system identifies whether the tip has become rounded before it can adversely affect workpiece machining, allowing for timely tool replacement or maintenance
Solution Approach 2:
The determining tool serves as an intermediary between the machining tool and the workpiece. Instead of directly machining the workpiece with a potentially degraded tool, the determining tool first evaluates the tool condition, providing information that mediates the decision-making process for whether to proceed with workpiece machining
3Duration of action of moving object
If the machining tool operates with a round tip end, then the tool continues to function, but mechanical strength decreases and vibration increases, lowering machining quality
Solution Approach 1:
The invention establishes a feedback mechanism where the shape of the machining tool tip end is continuously monitored using the determining tool. The camera captures images of machining marks on the slanting surface, and the control unit analyzes these images to determine tip shape changes. This feedback loop allows the system to detect rounding early and trigger appropriate responses, maintaining machining stability throughout the tool's service life

AI summary
A determining tool for use in determining the shape of the tip end of a machining tool that machines a workpiece held on a table while the machining tool moves relatively to the table includes a bottom surface adapted to be held on the table and a flat slanting surface inclined to the bottom surface and oriented across a direction in which the machining tool moves relatively to the table, the flat slanting surface being adapted to be cut through by the tip end of the machining tool.
