To achieve optimal results in abrasive water jet (AWJ) cutting, it is crucial to fine-tune the abrasive mass flow rate. Based on the study's findings, a flow rate between 250 and 350 g/min is recommended, as this range yielded the most favorable cutting width. Exceeding this range may lead to a decline in cut quality. Proper adjustment of this parameter not only enhances process efficiency but also contributes to cost savings by reducing abrasive material consumption. Similarly, the traverse speed must be carefully regulated to balance the trade-off between cut quality and productivity. Experimental results indicated that speeds between 0.2 m/min and 0.4 m/min were optimal for achieving the desired cutting width. While higher traverse speeds can shorten processing time and increase throughput, they may also compromise cut quality, potentially leading to additional post-processing costs. * _Effect on Cut Quality_  
Maintaining high surface quality in abrasive water jet (AWJ) cutting requires careful monitoring of process parameters to prevent the formation of unwanted scoring or surface irregularities. Key variables such as abrasive mass flow rate and traverse speed must be precisely adjusted to minimize their adverse effects on surface finish. Continuous testing and calibration are essential for ensuring consistent performance. Furthermore, real-time process control and monitoring--enabled by modern sensors and automation technologies--allow for the immediate detection of deviations in cutting parameters. This facilitates prompt adjustments, thereby optimizing cut quality and enhancing overall process reliability. * _Practical Applications_  
For industrial applications of abrasive water jet (AWJ) cutting, the implementation of optimal parameter settings, along with regular equipment maintenance and inspection, is essential for ensuring long service life and consistent system performance. Equally important is the monitoring and minimization of energy consumption. Companies employing AWJ technology should invest in employee training and the practical application of research findings. A thorough understanding of equipment setup and the influence of various process parameters is crucial for achieving high production quality and reducing operational costs. Well-trained personnel contribute to lower error rates and enhanced productivity over time. Additionally, minimizing waste generated during the cutting process--through optimized cutting paths and reduced material wastage--not only lowers raw material expenses but also decreases waste disposal costs. For industrial practice, it would be highly beneficial to develop a practical guide or directive that includes recommended cutting parameters for different wood species and material thicknesses. Such a document could significantly facilitate the implementation of AWJ technology in the woodworking industry and improve its efficiency in processing layered or harder wood materials.
