Machine Tool Control Method Diagonal Motion Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machining methods are inefficient due to suboptimal motion paths of machine tools, leading to increased machining time for plate-shaped workpieces.
Innovation Solution
A control method for a machine tool that optimizes the motion path by determining a raised height and maneuvering height, allowing simultaneous horizontal and vertical movement of the tool, with the computer controlling the tool to move vertically and horizontally to reduce travel distance and improve efficiency.

Engineering Contradiction Analysis
1Productivity
If the tool moves horizontally or vertically in sequence using conventional machining method, then the machining operation can be completed, but the overall time required for machining operation is increased
Solution Approach 1:
The patent applies dimensional change by enabling the tool to move diagonally in three-dimensional space rather than strictly horizontally or vertically. The tool moves from current machining position to next machining position along a diagonal path that combines horizontal displacement and vertical height adjustment simultaneously, reducing the number of separate movement steps and total machining time
Solution Approach 2:
The patent merges horizontal positioning and vertical height adjustment into a single coordinated motion. Instead of completing horizontal movement first then vertical movement (or vice versa), both movements are combined into one simultaneous diagonal trajectory, consolidating multiple operations into a single efficient motion sequence
2Reliability
If the tool moves vertically to stand-by height before horizontal movement, then proper positioning is achieved, but the motion path is suboptimal and time-consuming
Solution Approach 1:
The patent implements preliminary action by pre-calculating the optimal diagonal path between machining positions before execution. The system determines the raised height and maneuvering height in advance, and plans the combined horizontal-vertical trajectory beforehand, allowing the tool to execute the optimized path without intermediate停顿 or sequential adjustments
Solution Approach 2:
The patent applies dynamics by making the tool's motion path adaptive and flexible rather than fixed and rigid. The control system dynamically adjusts the combination of horizontal and vertical movements based on the specific geometry of the workpiece and the relative positions of machining points, optimizing the trajectory for each specific machining scenario

AI summary
A control method of a machine tool includes the steps of: determining a raised height, and determining a maneuvering height; causing the tool to move horizontally to a machining position; causing the tool to move vertically to a machining height to machine the workpiece; causing the tool to move vertically to the raised height, and when the tool is at the maneuvering height, causing the tool to move horizontally to a next machining position while the tool is moving vertically; causing the tool to move vertically to the maneuvering height while the tool is moving horizontally to the next machining position; and causing the tool to move vertically to the machining height to machine the workpiece.
