Water Jet Cutting Nozzle Control for Corner Quality

The patent applies dynamics by making the cutting speed variable rather than constant. The control device dynamically adjusts cutting speed based on the geometric characteristics of the workpiece - using higher speeds for linear portions and lower speeds for corner portions. This dynamic speed adjustment allows the system to maintain high overall productivity while ensuring precise cutting quality at critical locations like corners.

The patent implements local quality by applying different cutting speeds to different portions of the workpiece. Linear portions are cut at higher speeds for efficiency, while corner portions are cut at lower speeds for precision. This localized differentiation of cutting parameters ensures that each area receives the appropriate speed for its specific geometric requirements, resolving the contradiction between overall productivity and local cutting quality.

The patent applies self-service by enabling the control device to automatically calculate and determine the optimal nozzle angle based on the workpiece geometry and cutting conditions. Instead of requiring manual operator intervention, the system autonomously computes the necessary angle adjustments and implements them, thereby eliminating inclination of the cutting surface while avoiding the complexity of manual control procedures.

The patent implements feedback by using the control device to continuously monitor cutting progress and automatically adjust nozzle angle in response to detected conditions. The system receives information about workpiece geometry and cutting state, processes this data, and automatically modifies the nozzle angle to maintain optimal cutting quality, reducing the need for manual intervention and simplifying the overall control process.

The patent applies universality by creating a single cutting program that can adapt to various cutting conditions through automatic parameter adjustment. Rather than requiring separate programs for different cutting speeds and angles, the control device universally handles diverse cutting scenarios by dynamically modifying speed and angle parameters based on real-time workpiece geometry, thereby maintaining cutting quality while simplifying program management.

The patent implements parameter changes by automatically modifying cutting parameters (speed, angle, flow rate) during the cutting process based on detected workpiece characteristics. This dynamic parameter adjustment allows a single cutting program to effectively handle multiple cutting scenarios, eliminating the need to create and manage multiple separate programs while maintaining consistent cutting quality across different conditions.
