Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate analysis methods are used for computationally-machined surface profiles and actual machined surface profiles, then comprehensive error analysis can be performed, but identification time for defective surfaces and contour errors increases significantly
Solution Approach 1:
The patent merges the separate analysis processes for computationally-machined surface profiles and actual machined surface profiles into a single integrated display system. The display unit overlays both profile types on the same coordinate system, allowing simultaneous visualization and comparison. This combining of previously separate analysis methods enables comprehensive error analysis while dramatically reducing identification time, as users can now compare theoretical vs. actual machining results in one unified view rather than switching between separate analysis tools.
2Manufacturing precision
If detailed simulation and measurement processes are performed separately, then accurate machining error determination is achieved, but the overall process complexity increases
Solution Approach 1:
The display unit serves multiple functions within a single system: it displays computationally-machined surface profiles, displays actual machined surface profiles, performs overlay comparison, and provides error analysis. By making the display system universal and multi-functional, the patent maintains accurate machining error determination while reducing process complexity. Users interact with a single unified interface rather than multiple separate tools, simplifying the overall workflow while preserving analytical accuracy.

AI summary
The present disclosure is intended to provide a technique which enables a direct visual comparison between a computationally-machined surface profile determined based on motor position information and a machined surface profile obtained by actual measurement of a machined surface. A display unit includes: a motor position information acquirer that acquires motor position information including at least one of a command position or a real position of a motor; a machine information acquirer that acquires machine information including a drive shaft configuration, a tool geometry, and a shape of an unmachined workpiece; a machined surface profile simulator that performs a simulation of machining a workpiece based on a machining program, and determines a computationally-machined surface profile of the workpiece simulated to be machined, based on the motor position information and the machine information; a machined surface profile measurer that measures a machined surface profile of a machined workpiece that has actually been machined based on the machining program; and a machined surface profile display that displays the computationally-machined surface profile determined by the machined surface profile simulator, in parallel with the machined surface profile measured by the machined surface profile measurer.
