Abstract Veneer cutting is a specific machining process, where the chip is the final product. The objective of this article is to investigate on the optimal tool edge geometry, using particle swarm optimization (PSO) algorithm, to obtain the desired veneer thickness. The challenge is to maintain the best quality of veneer product with the control of pre-splitting condition and thickness variation. Numerical results obtained from PSO algorithm are compared and verified with the experimental ones. The proposed model allows us to predict the characteristic tool angles for different chip thicknesses and friction coefficients. For chip thickness range greater than 2 mm, the presplitting condition is no longer satisfied, as in the case of rotary peeling veneer, the need of using pressure bar becomes primordial.

用于单板切割过程的最佳刀具边缘几何形状的预测模型

摘要 单板切割是一种特定的加工过程，其中切屑是最终产品。本文的目的是研究最佳刀具边缘几何形状，使用粒子群优化 (PSO) 算法，以获得所需的单板厚度。面临的挑战是通过控制预裂条件和厚度变化来保持单板产品的最佳质量。将PSO算法得到的数值结果与实验结果进行了比较和验证。所提出的模型使我们能够预测不同切屑厚度和摩擦系数的特征刀具角度。对于大于2mm的切屑厚度范围，不再满足预分裂条件，如在旋切单板的情况下，使用压力棒的需求变得原始。
