Numerical Control Device Multi-Axis Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional numerical control devices face challenges in simultaneously controlling five or more axes, leading to increased machining time and difficulties in creating machining programs that maintain the correct position and orientation of tools with respect to workpieces.
Innovation Solution
A numerical control device that reads machining programs and divides the operation of five or more axes into sets of four or less, allowing for precise control without increasing machining time by prioritizing axis operations and interpolating positions accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tool is separated from the workpiece to change orientation, then the orientation of the tool can be changed, but the machining time is increased
Solution Approach 1:
The patent segments the five or more axes into multiple groups of four or fewer axes. Each group is controlled independently through separate control units, allowing the system to process complex multi-axis operations by dividing them into manageable subsets that can be executed without separating the tool from the workpiece.
2Manufacturing precision
If five or more axes are simultaneously operated, then the position and orientation can be precisely controlled, but the control system becomes too complex to handle
Solution Approach 1:
The control system is segmented into multiple control units, each responsible for a specific group of four or fewer axes. This segmentation reduces the complexity of each individual control unit while maintaining the overall precision of the system through coordinated operation of multiple units.
Solution Approach 2:
The patent introduces a control program that acts as an intermediary, coordinating the operations of multiple control units. This control program manages the division and coordination of axis groups, enabling precise position and orientation control without requiring a single complex control system.
3Manufacturing precision
If the machining program is created after tentative execution, then the correct position and orientation can be achieved, but the program creation becomes difficult and time-consuming
Solution Approach 1:
The patent performs preliminary segmentation of the machining program into multiple control programs corresponding to different axis groups. This preliminary action allows the system to prepare the control strategy in advance, making program creation more systematic and less time-consuming while ensuring correct tool position and orientation.
