Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wire electrode performs approach operation and escape operation according to the conventional machining program, then the wire electrode can complete the machining path, but the machining time is prolonged due to frequent non-machining periods
Solution Approach 1:
The invention extracts and eliminates the unnecessary approach and escape operations from the machining path. When multiple machining paths share common approach and escape routes, the system removes these redundant movements, allowing the wire electrode to transition directly from the end of one machining path to the start of the next path without returning to the original start point, thereby reducing non-machining time and improving productivity
Solution Approach 2:
The invention merges consecutive machining paths by eliminating the escape operation of the first path and the approach operation of the second path when they share the same route. This combining of operations allows the wire electrode to continuously machine along adjacent paths without idle movement, effectively reducing the total machining time while maintaining the完整性 of the machining process
2Manufacturing precision
If the wire electrode follows the complete machining program including all approach and escape paths, then the machining path is completed accurately, but the overall machining time increases
Solution Approach 1:
The invention selectively removes redundant approach and escape operations from the machining program while preserving the essential machining paths. By extracting only the necessary path information and eliminating repeated movements, the system maintains machining accuracy for the actual cutting paths while significantly reducing the time spent on non-machining movements

AI summary
A wire electrical discharge machine includes: a determination unit that determines whether or not a first route and a second route, each including an approach path, a machining path and an escape path in this order, are set in this order as a movement route of a wire electrode; and a wire movement control unit that, when the first route and the second route are determined to be set in a machining program in this order as the movement route of the wire electrode, causes the wire electrode to transition from the machining path of the first route to the machining path of the second route without moving the wire electrode along the escape path of the first route and the approach path of the second route.
