Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing numerical control systems face challenges in managing the increased number of control axes when integrating robot control, leading to higher costs and computational load, which can deteriorate machining performance.
Innovation Solution
A numerical control system that manages coordinate information in a designated format, allowing the robot control device to transmit coordinate values only when the format is set or switched, thereby reducing the number of axes managed by the numerical control device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of control axes is increased to manage both machine tool and robot control, then the robot control function can be added, but the cost and computational load increase
Solution Approach 1:
The patent makes the existing machine tool control system perform dual functions by enabling it to control both machine tool operations and robot operations through a unified coordinate system. The control device manages a common coordinate system that represents positions for both the machine tool workspace and robot workspace, allowing one control system to handle multiple functions without requiring separate robot control axes
Solution Approach 2:
The patent merges the machine tool control and robot control into a single integrated control system. By establishing a correspondence between machine tool coordinates and robot coordinates through a unified coordinate system, the control device combines both control functions into one system, eliminating the need for separate robot control axes
2Adaptability or versatility
If the number of control axes is increased to manage robot control, then the robot can be controlled, but the machining performance deteriorates due to increased computational load
Solution Approach 1:
The control device achieves multi-functionality by using a single coordinate system for both machine tool and robot control, eliminating the need for separate robot control calculations and maintaining high machining performance
3Adaptability or versatility
If the number of control axes is increased beyond the limit, then more functions can be added, but the numerical control device cannot accommodate additional functions
Solution Approach 1:
The patent enables the numerical control device to perform robot control functions by making the existing machine tool control system universal. Through coordinate system correspondence and a unified control approach, the device accommodates both machine tool and robot control within its existing control axes capacity
