Segmented Vibration Amplitude Setting for Machine Tool Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tools lack the ability to freely set the amplitude of reciprocating vibration along a predetermined movement path, limiting the flexibility and efficiency of the cutting process.
Innovation Solution
The machine tool divides the cutting path into multiple segments at predetermined coordinate positions, allowing individual setting of vibration amplitude for each segment, enabling precise control of the cutting tool's movement and vibration amplitude.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the amplitude of reciprocating vibration is controlled uniformly along the entire movement path, then the control system is simple, but the flexibility to adapt to different machining requirements is limited
Solution Approach 1:
The movement path is divided into multiple divided paths at predetermined coordinate positions, allowing the amplitude to be individually set for each segment. This segmentation enables flexible adaptation to different machining requirements while keeping the control system manageable through modular structure.
Solution Approach 2:
The amplitude control is made dynamic by allowing different amplitude values to be assigned to different segments of the movement path. The system can adjust the vibration amplitude according to the specific requirements of each path segment, providing adaptability without requiring complete system redesign.
2Manufacturing precision
If the movement path is divided into multiple segments with individual amplitude settings, then the flexibility and precision of vibration control is improved, but the control system complexity increases
Solution Approach 1:
By dividing the movement path into multiple divided paths at predetermined coordinate positions, the system achieves precise control of vibration amplitude for each segment. This segmentation allows high precision control while maintaining system clarity through modular organization of control parameters.
Solution Approach 2:
Different amplitude values are assigned to different divided paths based on local machining requirements. This local quality approach enables precise control where needed while avoiding unnecessary complexity in segments where standard amplitude settings suffice.
3Productivity
If a single amplitude value is used for the entire cutting path, then the control system is simple, but the ability to optimize cutting performance for different path sections is reduced
Solution Approach 1:
The cutting path is segmented into multiple divided paths, each with optimizable amplitude settings. This enables machining efficiency to be optimized for different path sections (such as varying feed rates, material hardness, or tool engagement conditions) while keeping the control architecture relatively simple through the use of predetermined coordinate positions for segmentation.

AI summary
A machine tool includes: a cutting tool for cutting a workpiece; rotating means for rotating the cutting tool and the workpiece relative to each another; feeding means for feeding the cutting tool and the workpiece in a predetermined machining feeding direction; vibrating means for reciprocatingly vibrating the cutting tool and the workpiece relative to each another; and amplitude control means for controlling the amplitude of the reciprocating vibration by the vibrating means. The cutting process is carried out by rotation of the workpiece and the cutting tool relative to each other and feeding of the cutting tool accompanied by the reciprocating vibration with said amplitude in the machining feeding direction of the cutting tool, to thereby move the cutting tool along a predetermined movement path relative to the workpiece. The movement path comprises a plurality of divisional paths divided at predetermined coordinate positions on the movement path. The amplitude control means is adapted to set the amplitude individually for each of the divisional paths.
